Screens for ApoE4 gene variant — the strongest known genetic risk factor for late-onset Alzheimer's disease. The ApoE4 variant is the most significant known genetic risk factor for late-onset Alzheimer's disease. Carrying one copy of E4 increases risk 3–4x, while two copies increase risk 8–12x compared to the most common E3/E3 genotype. This test identifies your specific ApoE genotype and its associated Alzheimer's risk. It is important to understand that ApoE4 is a risk factor, not a diagnosis — many E4 carriers never develop Alzheimer's, and many Alzheimer's patients do not carry E4. Results should be discussed with a healthcare provider and may inform lifestyle interventions that reduce risk. **Clinical use:** General health testing provides a baseline snapshot of organ function, metabolism, and key biomarkers — useful for annual checkups, preventive care, and tracking changes over time. ## Who should order it? Adults wanting a routine wellness baseline, anyone re-engaging with healthcare after a gap, and people tracking the impact of lifestyle or medication changes. ## Biomarkers measured - ApoE Genotype (Alzheimer's) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Labcorp | $184.99 | $190.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
