While you need some cholesterol to be healthy, having too much can build up in your arteries and may cause a heart attack or stroke.
There are different types of cholesterol to be mindful of-LDL (the "bad" cholesterol) and HDL (the "good" cholesterol), and it is importance to understand the difference between both.
To better understand goal levels for both cholesterol types based on your risk level, see our total LDL cholesterol and non-HDL cholesterol calculator below, or download the accompanying PDF.
How Do You Calculate LDL and Non-HDL Cholesterol?
The sum of Very Low Density Lipoprotein (VLDL) +LDL cholesterol is called non-HDL cholesterol. It is calculated routinely as total cholesterol minus HDL cholesterol. In persons with elevated triglycerides (TG), 200 - 499 mg/dL, most cholesterol occurring in the VLDL fraction is contained in the remnant VLDL, which is thought to be very atherogenic. The non-HDL-C level includes cholesterol carried in several atherogenic lipoproteins, such as LDL, very low-density lipoprotein (VLDL), intermediate density lipoprotein (IDL), and lipoprotein(a) (Lp(a)).
Therefore, in patients with elevated TG levels (200-499 mg/dL), treatment of the non-HDL-C level is a secondary target after the LDL-C target has been reached.
When triglycerides are ≥ 200 mg/dL, after LDL goal is reached, set secondary goal for non-HDL cholesterol for 30 mg/dL higher than LDL goal.
Comparison of LDL Cholesterol and Non-HDL Cholesterol Goals for Three Risk Categories
|Risk Category||LDL Goal (mg/dL)||Non-HDL Goal (mg/dL)|
|CHD and CHD Risk Equivalents (10-year risk for CHD > 20%)||Optional < 70 < 100||< 100 < 130|
|Multiple (2+) Risk Factors and 10-year risk ≤ 20%||< 130||< 160|
|0-1 Risk Factor||< 160||< 190|
