The cost of an APOE genetic test varies widely depending on provider, scope, and country. In Germany, a standalone APOE test (ε2/ε3/ε4 alleles) typically ranges from €50 to €150 when offered as a self-pay service (IGeL). More comprehensive panels that include APOE alongside other risk genes can cost €200–€500 or more. Importantly, statutory health insurance rarely covers the cost unless there is a documented familial lipid disorder; for Alzheimer's risk assessment, reimbursement is generally denied because no proven preventive or therapeutic benefit exists. Additionally, APOE ε4 is only a risk factor, not a diagnostic test. Its predictive value is limited, and the psychosocial impact of a positive result can be significant. Experts recommend pre-test genetic counseling. The evidence for clinical utility of APOE testing for risk prediction is moderate (association studies) but insufficient for a general recommendation. Without specific cost data from the provided context, this estimate is based on common practice.
