Computing your real LDL from the numbers you got from your doctor's office. This example shows that mistakes are made. Especially if your Trigs are below 100. This post is now in the header for reference.

TYP CONTRIBUTOR:

Dr Eades posted the formula in the comments to calculate LDL when TG is below 100. That formula was taken from this study.

The impact of low serum triglyceride on LDL-cholesterol estimation. ncbi.nlm.nih.gov

"For readings in mg/dl (units used in the US) use this equation:-

LDL = (total cholesterol/1.19 + triglycerides/1.9 - HDL/1.1) - 38

For readings in mmol/L (units used in Europe and the rest of the world)

LDL =(total cholesterol/1.19 + Triglycerides/0.81 - HDL/1.1) - 0.98"

Using the formula, ******** LDL calculates out to 150. His actual LDL was 153.
Pretty close. Compare to the Freidewald amount of 206.

My wife just came from the doctor where her test showed TC of 211, HDL of 72, TG of 46 and LDL was 130.

Her LDL calculates out to be 98. She knew about the Freidewald formula problem and told him about it. He blew her off and expressed real concern about her high LDL number.

I am now debating whether to send the formula to him or not.
