Overview
Apolipoprotein A1 (ApoA1) is important for assessing the risk of atherosclerotic cardiovascular disease and diagnosing Tangier disease. It plays a key role in reverse cholesterol transport, with higher ApoA1 levels more strongly associated with reduced risk of a first myocardial infarction than HDL-C concentrations. Additionally, low ApoA1 levels can predict preclinical atherosclerosis based on coronary artery calcium scoring.
What is the Apolipoprotein A1 Test ?
Apolipoprotein B (ApoB) is the primary protein component of low-density lipoprotein (LDL). Apolipoprotein A1 (ApoA1) is the primary protein component of high-density lipoprotein (HDL). Elevated ApoB and decreased ApoA1 are associated with increased risk of cardiovascular disease.
What is the Purpose of the Apolipoprotein A1 Test ?
This Test is advised for following assessments:
- Evaluate the Risk of Heart Diseases: Low levels of ApoA1 are associated with an increased risk of Cardiovascular diseases (CVD), such as Atherosclerosis and Coronary Artery Disease.
- Insight to HDL Functioning: It provides more detailed information about the quality and functionality of HDL Cholesterol compared to standard Lipid Panels.
- Diagnose and Monitor Lipid Disorders: Helps in diagnosing rare lipid metabolism disorders like Tangier disease and familial HDL deficiency.
- Monitor Effectiveness of Heart Treatments: Used to assess the effectiveness of lipid-lowering treatments, such as statins or lifestyle changes, in improving Cardiovascular health.
- Diagnosing the Inflammatory Conditions: ApoA1 levels may decrease in inflammatory states, providing additional clues in broader diagnostic contexts.
When is an Apolipoprotein A1 Test Recommended ?
The following are a few signs or conditions that could indicate the need for a Apolipoprotein A1 Test:
- Family History of Heart Disease
- Personal History of Early Heart Disease
- High Cholesterol Levels That Don’t Improve
- Atherosclerosis
- Unexplained Stroke or Heart Attack
- High Blood Pressure
- Chronic Kidney Disease
Preparation for Apolipoprotein A1 Test
- Unless otherwise directed by your doctor, there is no need for you to make any special preparations before the Apolipoprotein A1 Test.
- Other blood tests can be carried out in addition to a Apolipoprotein A1 Test. If your doctor advises you to have multiple tests at once, they may ask you to fast for a specific period of time prior to a blood test.
- Drink adequate water before sample collection.
- Avoid vigorous physical activity before the sample collection.
- Follow the preparatory instructions as guided by your doctor.
What is the Cost of the Apolipoprotein A1 Test ?
