Apolipoprotein B
Also known as: APO B-100
Use
The Apolipoprotein B test measures the amount of Apo B-100 in the blood, which is found in low density lipoprotein (LDL) and is used to evaluate the risk of atherosclerotic cardiovascular disease. A desirable fasting serum Apo B concentration for the prevention of cardiovascular diseases is less than 90 mg/dL. A fasting serum Apo B concentration of 130 mg/dL or greater corresponds to an LDL cholesterol concentration greater than 160 mg/dL and constitutes a risk-enhancing factor for cardiovascular disease.
Special Instructions
A fasting specimen is required for this test. The test is performed daily from Sunday to Saturday and reported within 24 hours.
Limitations
The test results can be affected if the specimen is not separated from cells within 2 hours of collection. Improper specimen handling could lead to inaccurate results.
