The apolipoprotein E (APOE) test detects the presence of the APOE E4 allele, which is the strongest genetic risk factor associated with late-onset (after the age of 65) Alzheimer's disease.
Each person inherits two APOE alleles—one from each biological parent—and the combination determines their genotype.
Your results will show if you have:
- one copy of the E4 variant, which indicates 3x risk for Alzheimer's
-
two copies of the E4 variant, which indicates 8-12x risk for Alzheimer's
