Q: What is the formula for figuring LDL?

I have my Total Cholesterol, HDL and Triglcerides levels. I know that there is a formula to figure LDL using these.  What is that formula?

Hi Shelley,

 

Formula to calculate total cholesterol:

 

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

 

So, to calculate your LDL means rearranging the formula:

 

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

 

All the best,

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

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

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