Ask your doctor to test your LDL cholesterol directly. For most lab tests, because it's inexpensive, the LDL number is indirectly calculated using the Freidewald equation (LDL = TC - HDL - [TG/5]...I get 145, in your case), but it seems to break down when your TGs get down to your level. See this post from Dr. Michael Eades:
The moral of this story is that if you have been following a low-carb diet and your triglycerides are low (or if your triglycerides are just low) and your LDL reading comes out a little high – or even a lot high, don’t let anyone mule you into going on a statin or undergoing any therapy for an elevated LDL. Demand to have a direct measurement of your LDL done.
