What is the formula for figuring out LDL cholesterol?
October 24, 2008

I have my Total Cholesterol, HDL and Triglcerides levels. I know that there is a formula to figure out my LDL using these, but I don't know what the formula is. Can anyone help?

The formula you’re talking about is this one:

Total Cholesterol = HDL + LDL + (Triglycerides x .20)

In your case, since you have the other numbers, you would rearrange the equation. Take your total cholesterol level, subtract the HDL, and subtract the triglycerides (that have been multiplied by .20). Here’s the written equation:

LDL = Total cholesterol - HDL - (Triglycerides x .20)

I hope that helps, and I hope that you get a number that pleases you. If you’d like some information on how to lower your LDL, you might try reading this article on simple steps you can take to lower your LDL levels.

These other articles may also help you understand the relationship between the numbers you’ve been given.

The Western Journal of Medicine has a different formula: LDL = cholesterol - (HDL + triglycerides/5). This and the one listed here give different results.

Never mind. Stupid math mistake on my part. I don't know how to delete my previous comment, but I would if I could.

LDL = Total cholersterol - HDL - Triglicerides/5

That is, total cholesterol minus HDL cholesterol minus one-fifth of the trigliceride level

The 'Total Cholesterol - HDL - (Triglycerides/5)' equation is not valid if the triglycerides are greater than 400.

hdl = 35, Total cholesterol = 148 and Triglicerides = 65
