APO A1

You should get an Apo A1 test if you have low HDL cholesterol, a family history of early heart disease, or risk factors like diabetes, obesity, high blood pressure, or smoking. It is also recommended when routine lipid results don't explain your heart risk, and for monitoring lipid-lowering treatment alongside Apo B.

Fasting for 10–12 hours is usually recommended before an Apo A1 test, especially if it is done with a lipid profile. You may drink water during this time. Avoid alcohol and fatty foods for 24 hours beforehand, and inform your doctor about any cholesterol-lowering medicines, hormone therapy, or oral contraceptives.
