Expected Value for lipid
The National Heart, Lung and Blood Institute issued the Third Report of the National C
holesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatm
ent of High Blood Cholesterol in Adults (Adult Treatment Panel III) in May 2011. The A
TP III report presented the NCEP’s updated clinical guidelines for cholesterol testing an
d management and described the following classifications for cholesterol and triglycerid
e testing:

Non-HDL
ATP III identifies non-HDL (total cholesterol minus HDL) as a secondary target of therapy in
persons with high triglycerides (≥200mg/dL). The goal for non-HDL in persons with high
serum triglycerides can be set at 30mg/dL higher than that for LDL cholesterol, on the
premise that a VLDL level ≤30mg/dL is normal.
1
Non-HDL can be calculated using the
equation below.
non-HDL (calculated) = Total Cholesterol - HDL
LDL
LDL can be calculated using the equation below. Calculated LDL is an estimation of LDL and
is valid only if the triglyceride level is 400mg/dL (4.55mmol/L) or below.
3
LDL (calculated) = Total Cholesterol - HDL - (Triglycerides/5) (mg/dL)
LDL (calculated) = Total Cholesterol - HDL - (Triglycerides/2.17) (mmol/L)
