Apolipoprotein A1 is the main protein of HDL particles. It is a measure of how many HDL particles are present.

What Apolipoprotein A1 measures

Apolipoprotein A1 is the main protein of HDL particles. It is a measure of how many HDL particles are present.

If your Apolipoprotein A1 is low

Apolipoprotein A1 below the range means fewer HDL particles, commonly associated with insulin resistance, smoking, high triglycerides or genetics.

Commonly associated with

• Insulin resistance
• Smoking
• High triglycerides
• Genetics

If your Apolipoprotein A1 is high

Apolipoprotein A1 above the range means more HDL particles, commonly associated with regular exercise, estrogen or moderate alcohol intake, and is generally read as favorable.

Commonly associated with

• Regular exercise
• Estrogen
• Moderate alcohol intake
• Genetics

Typical reference range

Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.

If it is within range

Your apolipoprotein A1 is within the range printed by your lab.
