Why Get Tested?

To determine whether or not you have adequate levels of apo A-I, to diagnose people with specific apo A deficiency and to help determine your risk of developing coronary heart disease (CHD)

When to Get Tested?

This is a not a routinely performed test and is currently limited to hospital specialists, and specialist testing laboratories. It can be measured when you have hyperlipidaemia and/or a family history of CHD or peripheral vascular disease; when your doctor is trying to assess your risk of developing heart disease; when apo A deficiency is suspected and when you are monitoring the effectiveness of lipid treatment and/or lifestyle changes.

Sample Required?

Usually, a blood sample taken from a vein in your arm

Test Preparation Needed?

None; however, this test is often requested at the same time as other tests that require fasting, so you may be instructed to fast for 12 hours prior to having this test.
