ApoE genotyping
ApoE genotyping is a lab test that identifies variations in the APOE gene, which provides instructions for producing apolipoprotein E, a protein involved in cholesterol transport and brain health. This test helps determine your genetic risk for developing conditions like Alzheimer’s disease. There are different versions, or alleles, of the APOE gene—mainly ε2, ε3, and ε4—that can influence your risk. By understanding your APOE genotype, healthcare providers can better assess potential risks and tailor prevention or management strategies accordingly.
