These use the highly specific binding between antibodies and antigens. The ELISA (Enzyme-Linked Immunosorbent Assay) is a classic example, used to detect everything from food allergens to HIV antibodies.
Genomic assays can determine if a patient has a specific mutation (e.g., HER2 in breast cancer), ensuring they receive a drug tailored to their unique biology. diagnostic assay
