Apolipoprotein E Genotyping, B
Test Summary
Determining the specific apolipoprotein E (APOE) genotypes in individuals with type III hyperlipoproteinemia. Determining the specific apolipoprotein E (APOE) genotypes that may increase risk for amyloid related imaging abnormalities in individuals being treated for Alzheimer disease with B-amyloid-targeting antibodies. APOE genotyping has been used to assess susceptibility for Alzheimer disease. However, the use of APOE analysis for predictive testing for Alzheimer disease is not currently recommended by the American College of Medical Genetics due to limited clinical utility and poor predictive value.
