APO B/APO A1(Ratio)

You should get an Apo B/Apo A1 ratio test if you have a family history of early heart disease, low HDL or high triglycerides, or risk factors like diabetes, obesity, metabolic syndrome, smoking, or high blood pressure. It is especially useful when routine cholesterol results seem normal but heart risk is high, and for monitoring lipid-lowering treatment.

Fasting for 10–12 hours is usually recommended before an Apo B/Apo A1 ratio 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.
