ADA Assay

Meaning

The Anti-Drug Antibody (ADA) Assay is a critical laboratory procedure used to detect and quantify antibodies developed by the immune system against a therapeutic protein, such as a recombinant hormone or peptide. These anti-drug antibodies can potentially neutralize the therapeutic agent, altering its effectiveness or leading to adverse immune reactions in a clinical setting. Monitoring ADA levels is a standard practice in the pharmacovigilance and development phases of biologic therapies, ensuring patient safety and treatment efficacy. Understanding a patient’s immunogenic response is paramount for tailoring hormonal replacement or peptide therapy protocols.
