How to Interpret Cholesterol Test Results

By Mark Sisson
260 Comments

Before we get into the big job of interpreting cholesterol numbers, let’s review what cholesterol actually is.

Cholesterol is cholesterol: a waxy steroid of fat that serves as an essential structural component of cellular membranes and in the production of steroid hormones, vitamin D, and bile acids. Contrary to what the terminology indicates, there’s actually only one “type” of cholesterol in the human body, and it’s called, quite simply, cholesterol. What we think of when we use the word “cholesterol” is actually a lipoprotein – a fatty conglomerate of protein and lipids that delivers cholesterol and fat and fat-soluble nutrients to different parts of the body. It’s not just free cholesterol floating around in your blood; it’s cholesterol bound up by lipoproteins.

So LDL, HDL, VLDL, all those (in)famous measurements we get at the doctor’s office are just different types of lipoproteins. They’re not actually cholesterol. I discussed this briefly a couple years back, and there’s always Griff’s big primer in the forum, so take the time to go check out both. And also take a peak at The Definitive Guide to Cholesterol for review.

Okay, let’s talk about the most commonly bandied-about cholesterol numbers: LDL-C and HDL-C. What do they really mean? What are they actually measuring?

To understand what these numbers mean, let’s play the freeway analogy game. Both LDL-C and HDL-C, the standard, basic readings you get from the lab, do not reflect the number of LDL or HDL particles – the number of lipoproteins – in your serum. Instead, they reflect the total amount of cholesterol contained in your LDL and HDL particles. Hence, the “C” in LDL/HDL-C, which stands for “cholesterol.” Measuring the LDL/HDL-C  and then making potentially life-changing health decisions based on the number is like counting the number of people riding in vehicles on a freeway to determine the severity of traffic. It’s data, and it might give you a rough approximation of the situation, but it’s not as useful as actually counting the number of vehicles. A reading of 100 could mean you’re dealing with a hundred compact cars, each carrying a single driver, or it could mean you’ve got four buses carrying 25 passengers each. Or it could be a couple buses and the rest cars. You simply don’t know how bad (or good) traffic is until you get a direct measurement of LDL and HDL particle number.

Say you go ahead and get those particle numbers directly measured. You’re still limited, because that is just a single datapoint from a specific time in your life/day/week. Analogies are fun and helpful, I think, so let’s take this traffic and freeway stuff further. To get an accurate idea of traffic, you need constant updates, right? Imagine you counted the number of cars on the freeway at 12:05 on a Saturday afternoon four weeks ago. That’s great, but what does it tell you about traffic at 5 PM on a Thursday? Even though it’s the same stretch of asphalt/artery, we can’t divine much at all from that single measurement. You need more data points. That traffic fluctuates wildly is entirely uncontroversial. Any southern Californian could tell you that. But did you know that LDL, HDL, and total cholesterol readings in the same person can fluctuate just as wildly, oftentimes enough to move that person from “desirable” to “high risk” and back to “desirable” lipid status without any nutritional or lifestyle changes in the span of a few mere weeks?

In biology, a single snapshot rarely, if ever, tells the whole story. Who woulda known?

But just because the standard cholesterol test is but a snapshot of a dynamic system in flux doesn’t negate the potential usefulness of getting your cholesterol checked. As much as Conventional Wisdom has gotten things wrong when it comes to cholesterol and heart disease, the two do have a relationship together. There is a connection; contrary to what the AHA might think, we just don’t have it ironed out yet. In my opinion, the most persuasive hypothesis about the real causes of atherosclerosis and heart disease comes from Chris Masterjohn and is highlighted in his recent AHS talk, “Heart Disease and Molecular Degeneration,” and on his blog. It’s a synthesis of the two prevailing notions regarding cholesterol and heart disease – the one which says elevated blood cholesterol plays no causal role in heart disease and the one which says elevated blood cholesterol is the primary cause of heart disease – and it goes something like this:

LDL receptors normally “receive” LDL particles and remove them from circulation so that they can deliver nutrients and cholesterol to cells, and fulfill their normal roles in the body.

If LDL receptor activity is downregulated, LDL particles clear more slowly from and spend more time in the blood. Particles accumulate.

When LDL particles hang out in the blood for longer stretches of time, their fragile polyunsaturated fatty membranes are exposed to more oxidative forces, like inflammation, and their limited store of protective antioxidants can deplete.

When this happens, the LDL particles oxidize.

Once oxidized, LDL particles are taken up by the endothelium – a layer of cells that lines the inside of blood vessels – to form atherosclerotic plaque so they don’t damage the blood vessel. This sounds bad (and is), but it’s preferable to acutely damaging the blood vessels right away.

So it’s the oxidized LDL that gets taken up into the endothelium and precipitates the formation of atherosclerotic plaque, rather than regular LDL. OxLDL, poor receptor activity, and inflammation are the problems. But since measuring oxidized LDL in serum is difficult (oxidized LDL gets taken up out of serum and into the endothelium rather quickly) and expensive, we need other, more realistic, more obtainable methods. We need to work with what we’ve got. It would be great if a doctor could quickly order up an “LDL receptor activity” test, but I don’t see that happening anytime soon.

Enter the various lipid panels.

First up is your basic lipid panel, the standard test the average doctor is going to order for a patient. If you go this route, you’ll typically get four measurements: total cholesterol (TC); high density lipoprotein cholesterol (HDL-C); low density lipoprotein cholesterol (LDL-C); and triglycerides.

Total cholesterol

What they say: Get that TC below 200, or else (you’ll have a heart attack or you’ll have to pay a higher health insurance premium, if we take you on at all).

My take: Mostly meaningless. Even though the epidemiological evidence suggests a TC between 200 and 240 mg/dl is best for all-cause mortality, we can’t hang our hats on it. First off, total cholesterol is limited because it’s only telling us the amount of cholesterol contained in all our lipoproteins without saying anything about what kind of lipoproteins we have or how many there are. Second, total cholesterol is limited because it’s determined by a bizarre formula – HDL-C+LDL-C+(Triglycerides/5) – that reduces various types of blood lipids, each with a different role in the body and a unique impact on our risk for illness, to mere numbers. Someone with low HDL and high triglycerides could easily have the same TC as someone with high HDL and low triglycerides, so long as the numbers work out. Whether it’s being used to predict wellness or disease, total cholesterol by itself is mostly meaningless.

HDL-C

What they say: “Good” cholesterol. It’s the “garbage truck” that cleans up “excessive” cholesterol and fat from tissues, so the higher the better! Though men and women should strive for levels exceeding 60 mg/dl, above 40 is acceptable for the former and above 50 is acceptable for the latter.

My take: Higher HDL-Cs correlate strongly with better cardiovascular health. No real argument here. Higher HDLs are desirable. Just remember, it’s only a snapshot of a glimpse into the cholesterol content of your HDL particles. Among most groups tested, the TC:HDL ratio is actually a strong indicator of heart disease risk, with higher ratios corresponding to higher risks. Note, though, that no Primal Blueprint adherents were among the groups analyzed, ever.

LDL-C

What they say: Get it as low as humanly possible! I want that low density lipoprotein so low as to be nearly nonexistent. Your body obviously hates you; otherwise, it wouldn’t be producing a potently toxic substance and sending it directly into your endothelial cells to form atherosclerotic plaque! Of course, we’re not actually measuring the number of low density lipoproteins, just the amount of cholesterol contained in them, but still!

My take: While a high LDL-C may indicate a problem, remember that LDL-C only indicates the total amount of cholesterol in your LDL particles. You could easily have a few large particles (good) or a bunch of smaller, denser ones (bad, might indicate poor LDL receptor activity and an LDL that likes to hang out in the blood), but LDL-C alone isn’t enough to know. It’s also just a moment in time, whereas what you’re interested in is the trend. If the trend indicates a steady rise in LDL-C, however, that could hint at poorer LDL clearance and lower LDL receptor activity (and greater susceptibility to oxidation).

Triglycerides

What they say: Lower would be better, sure, but you really gotta do something about that LDL! Anything less than 150 mg/dl is fine.

My take: High triglycerides correlate strongly with low HDL and smaller, denser LDL. High triglycerides, then, could indicate more oxidized (or oxidizable) LDL. The triglycerides of most Primal eaters, especially those on the lower carb side of things, usually hover well below 100 mg/dl. Triglycerides come packaged in VLDL, or very low density lipoproteins (which are calculated by dividing your triglyceride count by 5).

So, what can we learn from a standard lipid test? Not much, actually. We can learn from standard lipid tests, however. If we take a series of regular ol’ lipid measurements, preferably one pre- and several peri-Primal, we can get an idea of our metabolic health. Look for:

  1. Trends – Are your triglycerides going down over time? That’s great. Is your HDL trending up? Also good.
  2. Normal fluctuations – Your numbers can jump around 20-30 points in either direction between readings without it necessarily meaning anything.
  3. TC:HDL-C ratioLower is better and indicates fewer LDL particles.
  4. Triglyceride:HDL-C ratioLower is better and indicates larger LDL (and, usually, fewer) particles. Ideally, this will be close to 1 or lower; one study (PDF) found that 1.33 was the cut off.

If you’re going to get your cholesterol tested, and the basic labs just aren’t cutting it, you might as well go for one of the premium lab tests: the NMR LipoProfile or maybe the VAP. Rather than rely on indirect estimates and formulas, NMR and VAP directly measure the  size of your lipoproteins. I find NMR to be far more useful, because in addition to measuring particle size, it measures particle count (whereas VAP only estimates the count).

But you probably have holiday shopping to do, and I don’t want to drone on for too long, so I’ll leave it at that for now. Next week, I’ll pick up where I left off and get into what you can expect from NMR and VAP testing, including the downsides and the advantages. After that, I’ll go into some strategies for improving your numbers – or, rather, improving your health which in turn should improve your numbers.

Thank you, Mark, for spelling this stuff out so well. Seems like an overarching theme is inflammation aiding the process of oxidation which turns those dense LDLs into plaque-forming foam cells. Seems like fructose and grains and too much PUFA significantly increase inflammation. Not to mention, fructose increases triglycerides packaged in VLDL (from Dr. Lustig’s “Sugar: The Bitter Truth”), and high VLDL correlates with low HDL and smaller, denser LDL. Seems like removing or significantly reducing fructose, grains and PUFA would significantly reduce the ability of LDLs to “catch fire.” I’d like to find more info about the role of… Read more »

As an RN, I’ve seen plenty of people prescribed statins based on the results of a single lipid panel. “Surely you jest”, I’ve screamed in my head! Thank you for not only presenting this complex subject in terms we can understand, but for pointing out that fluctuations exist and trends need to be studied in order to get a better picture of one’s metabolic health.

I was told with a Total of 198 and HDL of 59, LDL 133 (bit high yes) and Trigly of 30 I would probably need to go on statins if it wasn’t down by my next visit. Guess what, I didn’t go back! I was GF at the time but not primal, this spring I might see what my numbers are but I decided I didn’t want to worry about it. Being 33 or so at the time I think the risk of the meds was higher than the benefits! So YES they do do that!

A couple of months ago I began an effort to raise my cholesterol. For a few years, my doctor and I have been trying to treat my hypothyroidism and raise my hormone levels (progesterone, DHEA, good estrogen) with little luck. Then one day I read something about a stong correlation between high cholesterol and hypothyroidism. That threw me because every time I have my cholesterol checked, my LDL doesn’t even register. Plus, my blood pressure has always been extremely low. Then I read and article on Mom on a Mission about the importance of cholesterol in making hormones and a… Read more »

Can you talk more about the gold rings turning your finger black? I haven’t heard of that as a symptom of a hormone imbalance before- do you have any links? Or know of the mechanism via which it happens?

Unfortunately, I can’t find anything online on the subject. Years ago, a doctor told me it meant low iron. My current doctor had tested all my mineral and vitamin levels and when she had made a long grocery list of supplements, I noticed iron wasn’t on it. I asked why not when I obviously had low iron and showed her my ring finger which was black from hand to knuckle. She immediately stated that it wasn’t low iron but low progesterone and then we tested all my hormone levels. Sure enough, they were in the basement. I have since noticed… Read more »

If you’re having issues with hypothyroidism (Hashimoto’s), read this book.

It’s basically about “quieting” the autoimmune response. Mineral supplements + primal eating have eliminated the majority of my symptoms — some I didn’t even realize were thyroid-related. The number one thing is that wheat is a total no-no. It exacerbates the immune response brought on by Hashimotos.

Make sure your mineral levels are correct. If Iron, Copper, Magnesium, etc are out of whack it can drive bad cholesterol up. I have found out the hard way that when you make dramatic changes to your diet it’s easy to screw up your minerals and electrolytes. If you are having muscle cramps and your blood tests show either too high or too low Iron these are all symptomatic of poor mineral intake or balance.

additionally, the “your fine, no problem” response is the common one doctors everywhere give to people who come into their office looking to find out what’s going on with their body when something has CHANGED. If it CHANGED, then it’s not normal is it? There is such a thing as subclinical illness. When it becomes clinical is only when it’s time to purchase some medications. I think most people would like to get their problems sorted before that point…

You can buy a test kit for home. The reviews say to let the blood come out on its own instead of squeezing the finger and you will get a more accurate number. I haven’t purchased one myself.

Note that most modern lab tests typically measure total cholesterol, HDL-C, and triglyceride levels, using the above formula to calculate LDL-C levels. Unfortunately, said formula assumes triglycerides are 150 or higher, so for primal / low-carb eaters will overestimate LDL-C levels. Dr. Eades wrote a blog post on this awhile back if you are interested in the details. As a side note, my total cholesterol is around 220 (up to 245 at one point) and my doctor has been trying to get me to take statins or aspirin for years.

TG 103? TG as in triglycerides?
Sorry to say this but that’s high for eating primally.
TG above 70 could mean either fluffy, billowy LDL or small, dense LDL.
Up to 140 it’s a 50/50 chance the LDL isn’t the good kind.
If TG is under 70 then LDL are always fluffy and no particle size tests are needed.
Good Luck!

Note that the Triglyceride:HDL-C ratio, which should be less than 1.33, is actually calculated using mmol units. You can convert your mg/dL units by multiplying triglyceride readings by 0.01129 and you can convert your HDL-C readings by multiplying by 0.02586.

So your (tg X 0.01129) divided by (HDL-C x 0.02586) should be less than 1.33

(Or you can just divide your US TG/ US HDL-C and make sure it’s less than 3.05, which is the same as 1.33*0.02586/0.01129)

THANKS!! I live in Australia so mmol is the scale. I crapped myself over the tg/HDL-C ratio until I read your comment here. I’ve been Primal 4 months and my TC, HDL, LDL and (most disappointingly) my tg all increased substantially, with some entering CHD risk zone. On USA scale my numbers were TC 301, HDL 58, LDL 208, tg 177. I would not worry about TC or LDL if tg was low. Bummer. But at least I know my tg/HDL is 1.33 not 3 !

In short, tube gel electrophoresis, gradient electrophoresis, VAP and NMR give wildly different results. If the larger medical community can’t even agree on a the proper way to measure certain profiles, we cannot yet determine whether these profile offer valuable clues into heart health.

Tube gel electro and gradient electro aren’t even used by cardiologist that much unless they have a patient that has several risk factors as well as past cardiac events. The VAP and NMR do not give “wildly” different results. They give very consistent results if both are ran on one patient. Each just have a few other subcomponents compared to the other. Both are very good at detecting risk.

Waterlilly (there was no reply button by your post.), In the podcast, Chris Masterjohn’s only example of wildly different results was between tube gel electro and VAP. Nonetheless he used that to illustrate his larger point that “There’s a lot of disagreement between these different tests. …Until we…get the science to the point where we can actually agree on the particle size, you know, on what tests we use, on what standards we use to classify someone as having this or that particle size or this or that distribution, I really don’t think we’re at the point yet where we… Read more »

I have genetically high-cholesterol but my LDL are almost exclusively the “large and fluffy” kind. This is encouraging as I attempt to figure out how to live life without statins. I have done too much reading to subject my body to them!

My take for heart health (thus far) is to have an anti-inflammatory lifestyle similar to what Chris Masterjohn’s research suggests. Thankfully I have found a doctor willing to work with me. 🙂

Hi, Im confused about the last part about the ratios: TC:HDL-C ratio – Lower is better and indicates fewer LDL particles.
Triglyceride:HDL-C ratio – Lower is better and indicates larger LDL (and, usually, fewer) particles. Ideally, this will be close to 1 or lower; one study (PDF) found that 1.33 was the cut off.

Can someone please help me understand this? I want to find out if I have big LDL (good) or small. My HDL=89, my Tri=55..
Thank you

Your triglyceride:HDL ratio is .62, which is well below what it should be (which is actually 3.05 if you’re American, as they use different measurements than in the linked study).

since your Triglyceride to HDL ratio is .62 that is lower than 1. So that is good. Lower indicates Larger LDL

I didn’t see you mention it, Mark, but I think it’s widely accepted that eating animal foods contribute to cholesterol. Having said that and using your highway analogy, wouldn’t it be better to reduce traffic on the artery highways by cutting the total number of passengers (limiting animal foods/ cholesterol), rather than worry more about traffic accidents (oxidized LDL)?

Rob

Karen, if you want to get your TC and LDL down fast, you may be able to do it with psyllium. I experimented on myself and both TC and LDL went down about 35% in 3 weeks. I took 2 Tbsp in a big glass of water twice a day (morning and night), and was amazed at the results. I recommend pure psyllium (no sugar) which you can get at Trader Joe’s or Whole Foods. Good luck!

You can just eat oats, without the bad side effects of your chicken feed. Problem is, the grains are what supress the liver in making cholesterol to repair cells, fight invaders and produce bile and hormones for proper digestion of fat and fat soluble vitamins for healthy bone and teeth. This is why the older ppl get, the less bone density they have. It’s why ppl suffer from hair loss, blindness, colon cancer and high triglycerides. Psyllium falls under the category of grains, it isnt healthy. To raise HDL = wine, dark chocolate To lower LDL = anti-oxident supplements and… Read more »

Good article. Especially on how meaningless one test is. I’ve got my own cautionary tale on that: My dad, whose cholesterol was always on the higher end of normal typical to our family history, was actually put on Statins because of a single really high cholesterol test result. Doctor scared the crap out of him. He was following a high fat/protein/vegetable diet per my recommendation, though not really primal as he does eat grains (white rice and whole wheat stuff). He’s a college professor, and less than a year later, he started having memory problems. He’d be in class and… Read more »

Happened to my grandmother, as well, and I also was the one who recommended seeing if the memory loss and dementia-type symptoms were statin-related. Statins can wreak havoc on some people, and physicians just are not looking out for those side effects being caused by them.

Okay folks, listen up! I stopped eating wheat…and my cholesterol dropped by 40 points! Don’t ask me ‘which one’…I don’t have the results in front of me. My doc was incredulous when I told him I still eat butter, eggs, bacon, chicken, turkey, steak, berries, and of course…veggies…but none of the ‘whole grains’ that he suggested I put back into my lifeplan. Now…stay tuned for the Dexascan results….I have a bet with him on that one!!!

I think that when it comes to figuring out if you’re in danger of heart disease and/or a stroke, the C-Reactive Protein Test is much more meaningful and reliable than any kind of cholesterol number.

The CPR is very unreliable as it may has the tendency to detect other inflammatory markers not related to cardiac tissue. It has the ability to detect inflammation else where in the body and give a falsely elevated reading. The LDL Particle number is what you really need to know in order to assess your risk.

The single best article I’ve ever read about cholesterol was written by Dr. Natasha Campbell-McBride, who some of you might know from the GAPS protocol.

Her explanations are so simple, yet so stunningly LOGICAL and SENSIBLE. This should be, without question, required reading for all medical students, nurses, nutritionists, and anyone else who likes to think they know anything about health.

This is simply untrue. The standard lipid panel doesn’t give the full picture or detect residual risk. The NIH recommend using an expanded lipid panel to at least know your LDL particle number. New guidelines for using the expanded lipid panel such as the NMR will be out in no time. Please do your research and know your underlying risk factors.

Don’t you think eating tons of animal fat will give you high LDL and Triglycerides? It’s why I don’t eat primal, besides the fact a life without grains is extremely depriving. I would get the facts about dietary cholesterol affecting one’s cholesterol before I blindly follow this Primal ideology. I really don’t know, but I am hesitant to eat loads of animal fat without monitoring it. I wonder the relation between insulin release from grains and it’s impact on absorbing fat and cholesterol. But still, is eating brown rice, skinless chicken breast and broccoli, really a bad thing?

Dear Jeremy,

Allow me to direct you to the button at the top navigation bar in red called “Start Here”.

No, eating animal fat does not give you high LDL and tris.

Skinless chicken breast? I guess, but I can think of many tastier, more nutritious options.

Broccoli? We Primals eat plenty of it.

Brown rice? Ugh. Why are even talking about this? Gut irritant, micro RNA, blood glucose spiker, oy vey!

The Primal diet does not advocate eating “tons” of animal fat. You need to read Mark’s book, or search his website for info on a proper primal diet. As for going with grain and low-fat options, wait and see in 20 or so years when your dementia kocks in. I’m not trying to be a wise-ass, but our brains absolutely require cholesterol to thrive. Limit cholesterol and you are essentially causing your brain to atrophy.

I’ve read extensively about all of this (including Gary Taubes and others). The weight of evidence seems to support the hypthesis embraced by the Primal community that: – Excess carbohydrates are more likely to be the cause of various health problems and poor blood lipid profiles than dietary cholesterol or saturated fat; – Elevated cholesterol (even LDL) is not a significant CHD risk factor UNLESS triglycerides are elevated. While I was already slim, fit and healthy, that research convinced me to pursue a restricted carbohydrate (primal) diet for the last 4 months. Of all the blood lipid numbers, I’m most… Read more »

What did you eat prior to the test, the night before?

Some people get inflammed eating fibrous plants with indigestible cellulose…others drink ultra-heated milk and get severe inflammation for 3 days or more… My Triglycerides were 140 on an ‘organic’ whole grain (mostly sesame bread and soy spread) diet combined with periods of starvation to keep weight off.
