Atherogenic Index
The Atherogenic Index is a calculated ratio (typically total cholesterol minus HDL, divided by HDL) that estimates the risk of developing atherosclerosis and cardiovascular disease.
Category: Lipid Panel
Also known as: atherogenic index, index ateroskleroze, ai, indeks ateroskleroze
Reference range: 0–3 ratio (Source: ABIM)
Standard unit: ratio
High values may indicate
A high atherogenic index indicates increased risk of atherosclerosis, coronary artery disease, and cardiovascular events.
Low values may indicate
A low atherogenic index indicates a favorable lipid profile and lower risk of cardiovascular disease.
Frequently asked questions
- What is a normal Atherogenic Index level?
- A typical reference range for Atherogenic Index is 0–3 ratio (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Atherogenic Index measured in?
- Atherogenic Index is most commonly reported in ratio. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Atherogenic Index reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Atherogenic Index over time?
- Yes. Upload results from any lab and BloodId charts your Atherogenic Index over time against its reference range, so you can see whether the trend is rising, falling, or stable.
