Apolipoprotein A-1

Order Code
11007
CPT
82172
Test Details
Synonyms

Apo A-1, Apolipoprotein A, Apo A

TAT

Stat-1 hour, Routine-4 hours

Methodology

Immunoturbidimetry

Reference Interval

Males: 1.04 - 2.02 g/L Females: 1.08 - 2.25 g/L

Remarks

In addition to the classical HDL/LDL‐cholesterol determination, a high level of Apo A‑1 (HDL) and a low level of Apo B (LDL) correlate best with a low risk for diseases such as atherosclerosis, coronary heart disease, and stroke. Apo A‑1 is also reported to be an early marker of coronary artery disease (CAD) and may be helpful in the screening of younger patients. Apo A‑1 levels can also be altered in other clinical conditions such as liver disease, inherited hypo‑α‑lipoproteinemia (e.g. Tangier disease), sepsis, pregnancy and as a result of estrogen administration (e.g. oral contraceptives).

Results are reported in SI units (g/L).
