This invention relates to the field of
gene detection technology, and in particular to a primer-probe combination, product, and application for detecting Alzheimer's
disease. The primer-probe combination and kit provided by this invention can simultaneously detect Alzheimer's
gene mutations and
methylation, effectively distinguishing between Alzheimer's patients and non-Alzheimer's subjects. It achieves low-invasiveness, low cost, high sensitivity, and high specificity in Alzheimer's
disease detection. The overall sensitivity for detecting Alzheimer's blood samples reaches 88.89%, and the specificity for detecting non-Alzheimer's blood samples reaches 95.74%, reducing the probability of false negatives and demonstrating high accuracy.
