Apo A1/B Ratio
Lipids & Cardiovascular
Ratio of protective vs atherogenic lipoproteins. Key cardiovascular risk indicator.

The Apolipoprotein A1 to Apolipoprotein B ratio is widely regarded by researchers as one of the most accurate ways to evaluate cardiovascular disease risk. Unlike standard cholesterol panels, this ratio captures the balance between protective and harmful lipoprotein particles. Wellth offers this test through accredited Swedish laboratories, giving you laboratory-grade insight into your heart health.
Testing the Apo A/Apo B ratio is valuable because it predicts heart attack risk independently of total cholesterol and triglyceride levels. If you have a family history of cardiovascular disease, chronic inflammation, elevated triglycerides, or high blood sugar, this ratio can reveal risks that standard lipid panels may miss. It is also an excellent way to track the effectiveness of dietary changes, exercise, or medication over time.
What a high value can mean
A high Apo A/Apo B ratio is generally favourable. It suggests that you have more protective HDL-associated protein relative to atherogenic LDL-associated protein. Factors such as regular physical activity, moderate alcohol intake, statin use, weight loss, and healthy estrogen levels can contribute to a higher ratio. A high ratio is associated with a lower risk of cardiovascular disease.
What a low value can mean
A low Apo A/Apo B ratio indicates that atherogenic particles outweigh protective ones, increasing cardiovascular risk. Common causes include chronic kidney disease, untreated diabetes, obesity, smoking, a diet high in saturated and trans fats, and certain medications such as beta-blockers and diuretics. Genetic factors can also play a role. A low ratio warrants further evaluation and lifestyle intervention.
Avoid fatty foods and alcohol the day before the test. Bring valid identification.

Your values appear in your account with reference ranges and an explanation of each marker.
A higher ratio is better. Values above 1.0 are generally considered protective. Your healthcare provider can interpret your specific result in context with your overall lipid profile.
Many researchers consider it a more reliable predictor of cardiovascular disease than total cholesterol or LDL alone, because it directly reflects the balance of protective versus harmful lipoprotein particles.
If you are at increased cardiovascular risk or making lifestyle changes, retesting every 3 to 6 months is common. Otherwise, annual testing is typically sufficient.
Fasting is not strictly required, but you should avoid fatty foods and alcohol the day before. Follow the preparation instructions provided when you order your test.
