# ApoE Genotype

> ApoE Genotype is measured with a standard blood draw; no fasting is needed. At TestWell it's $133.99 all-in as ApoE Genotype (Cardiovascular Risk), results in 5–7 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

Also known as: apoe genotype, apo e genotype, apo e genotyping result, apoe genotyping result, apolipoprotein e genotype, cardio iq apoe genotype.

## What does ApoE Genotype measure?

Which two copies of the APOE gene you inherited (ε2, ε3 or ε4). The ε4 variant is associated with higher LDL cholesterol and a higher lifetime risk of late-onset Alzheimer's disease; ε2 with lower LDL and lower Alzheimer's risk. A genotype is a risk factor, not a diagnosis.
