Cholesterol, Serum or Plasma
Also known as: CHOL
Use
This test is used to evaluate cardiovascular risk. Serum cholesterol levels are used in the assessment of the risk of developing atherosclerotic cardiovascular disease. A desirable serum cholesterol concentration in adults is less than 200 mg/dL and less than 170 mg/dL in children.
Special Instructions
The test uses cholesterol serum or plasma collected in a plasma separator tube or serum separator tube. Ensure the serum tube clots completely at room temperature before separating serum or plasma from cells within 2 hours of collection.
Limitations
Assay interference (negative) may be observed when high concentrations of N-acetylcysteine (NAC) are present. Negative interference has also been reported with NAPQI (an acetaminophen metabolite), but only when concentrations are at or above those expected during acetaminophen overdose.
