Introduction
Apolipoprotein A (apoA) reference ranges typically vary by sex. In females, the normal range is generally 0.94–2.63 g/L, whereas in males, serum apoA levels usually fall within 0.8–2.3 g/L. Values exceeding these reference ranges upon testing often indicate hyperlipidemia.
Apolipoprotein A (apoA) is a key structural component of lipoproteins and plays a critical role in lipid metabolism. Some patients present with abnormal physical findings, and to rule out hyperlipidemia, this test may be required. However, many individuals are unfamiliar with the normal reference range for apolipoprotein A. So, what is the normal range for apolipoprotein A1?
What is the normal range for apolipoprotein A1?
The normal range for apolipoprotein A1 varies by sex. In females, the typical reference range is 0.94–2.63 g/L; in males, it is generally 0.8–2.3 g/L. Values exceeding these upper limits may suggest hyperlipidemia; however, elevated levels can also occur in conditions such as alcoholic hepatitis.
Conversely, values below the lower limit of the normal range may indicate acute hepatitis, cirrhosis, malnutrition, or atherosclerosis. Any deviation—whether above or below the normal reference range—is considered abnormal. Patients should cooperate closely with their physicians to undergo further diagnostic testing for accurate diagnosis and timely treatment, which facilitates better disease management and recovery.
When apolipoprotein A1 testing is clinically indicated, it is generally recommended to perform the test in the morning after an overnight fast. Fasting helps ensure result accuracy and reduces the risk of misdiagnosis. We hope this information is helpful to you.
