    I'm pretty sure total cholesterol was measured correctly, whereas LDL was just wrong due to the calculation error.
    It's not circular. What I'm saying is when trigs are low (<100), the Friedewald equation is usually off on calculating LDL by around 20%. I'm assuming if you're giving a direct LDL measurement, you'll be about 20% lower. I'm simply taking 80% of her LDL number and plugging it back into the equation. It's not perfect, but it's probably more accurate than what it is now.

    Yes.

    I'm saying get your LDL, HDL and trigs directly measured. Then, calculate your TC. Basing your LDL's and totals off a standard cholesterol test is kind of silly. IMO, it's only valid to see your HDL:trig ratio. In this case, it is EXCELLENT.

    This whole conversation is very interesting and makes a lot of sense. I really appreciate all of you taking the time to comment.

    No no no choco....

    LDL is calculated.

    TC, HDL and Trigs are measured.

    With that formula, my LDL level is 111. I guess that's better?

    Your total cholesterol number isn't correct, anyway. Your trigs are too low, so your LDL cholesterol isn't calculated correctly. It's not a direct LDL measurement, it's almost certainly an estimate based on the Friedewald formula for LDL calculation. As you can see, when trigs are low, the number is wildly inaccurate. This guy's calculation (posted above) was off by over 45 points!

    In short, you do not know your total cholesterol. Your LDL is a calculation, likely off by about 20-30%, which will skew your totals horribly. It's all wrong.

    Get a direct LDL measurement, an LDL particle test and a C-reactive protein test. Add this info to your HDL and trig numbers and you'll have a better feel for your health.
    What rubbish. The TC is a direct measurement. It is only the LDL that is calculated by an approximation. You really shouldn't display your ignorance so confidently

    I'm pretty sure you can get your LDL measured with the deeper bloodwork analysis.

    Of course you can....but then the formula would be HDL+LDL= TC. Pretty freaking easy then . In fact you don't even need that formula cause you always have the TC and HDL measured anyhow! Choco just made a mistake in the beginning of this whole thing starting with his first post. No big deal. But these are the facts.

    Point is the LDL is usually calculated on standard cholesterol tests via the formulas we have been discussing. If you directly measure the LDL there is no reason to bother with such extrapolations right?
