Immunoassays & ELISA: Principles, Validation & Troubleshooting

Immunoassays sit behind hormone and cardiac tests, blood screening, allergen and mycotoxin checks in food, and drug measurements in biopharma. This SkillCert Practitioner course explains how antibody binding becomes a number, why each bench step matters, and how to tell a reliable result from a misleading one. You will learn the main assay formats and detection systems, good ELISA practice, standard curves and run acceptance, the difference between validating a method and verifying a kit, and how to spot faults and interference such as the hook effect, heterophile antibodies and biotin. Each module includes practical toolkit documents you can use at work.

Immunoassays are among the most widely used tests in clinical, food, veterinary, research and biopharma labs, and employers look for analysts who can run them correctly, judge whether a run is acceptable and spot misleading results. The course suits graduates preparing for QC and lab roles and junior staff who want to move from following a kit insert to understanding it.
