Question by Kumari: What is the difference between cholesterol and total cholesterol values?
Is there a cholesterol value independent of total cholesterol? If so, is it used as part of the formula for total cholesterol. And how do HDL and LDL fit into the measurement of cholesterol vs total cholesterol. Any references would be appreciated. Thank you.

Answer by Stephen
Most labs measure total cholesterol & HDL cholesterol and use mathmatic formular to calculate LDL cholesterol. This works unless the triglycerides are high

Answer #1
Total cholesterol = LDL + HDL + (1/5 triglycerides)
For example, if one has HDL of 40, LDL of 100 and triglycerides of 100, then the total cholesterol = 100 + 40 + (1/5 of 100=20) = 160.
The LDL/HDL ratio is as important or more so than the total, and 2.5 or less is good. 100/40 = 2.5
