The Apolipoprotein – A1 Test is a quantitative test to help identify if there is an adequate amount of Apolipoprotein – A1, which determines the risk of cardiovascular disease.
What is Apolipoprotein – A1 Test
Apolipoproteins are the major components of HDL- High-Density Lipoprotein. Lipids are not soluble by themselves in blood and apolipoproteins help dissolve the lipids and transport them through the bloodstream. Deficiencies in Apo A-1 leads to cardiovascular diseases. The decrease in Apo- A1 may also be due to chronic kidney disease, obesity, uncontrolled diabetes etc.
Why is Apolipoprotein – A1 Test suggested?
The Apolipoprotein – A1 Test is suggested in the following cases:
- A low value of HDL-C.
- High cholesterol and triglycerides.
- During assessment for Cardiovascular Disease.
- In cases of family history of cardiovascular disease.
How is an Apolipoprotein – A1 Test performed?
The Apolipoprotein – A1 Test is a short procedure.
- A vein is located, often inner arm and the area is cleaned.
- A needle is used to draw blood from the vein.
- An adhesive is placed after the sample is drawn.
- The sample is sent to the laboratory for testing.
What are the parameters measured in the Apolipoprotein – A1 Test?
The Apolipoprotein – A1 Test tests for an adequate quantity of Apolipoprotein -A1, as it the major component of HDL – High-Density Lipoprotein which determine the amount of cholesterol in the body.
Preparation before performing Apolipoprotein – A1 Test
The Apolipoprotein – A1 Test does not require any fasting, but it is usually performed alongside a lipid profile which requires 12 hours of fasting.
Post-care after Apolipoprotein – A1 Test
The Apolipoprotein – A1 Test does not have any side effects that require treatment or attention.
Sample types in Apolipoprotein – A1 Test
The reference range of Apo-A1 varies by sex and is as follows:
- Greater than 120 mg/dL (1.2 g/L): Negative.
- Lesser than 120 mg/dL (1.2 g/L): Likely to have cardiovascular disease
- Greater than 140 mg/dL (1.4 g/L): Negative.
- Lesser than 140 mg/dL (1.4 g/L): Likely to have cardiovascular disease.
Side Effects of Apolipoprotein – A1 Test
The drawing of blood might make a few people feel dizzy.
