Used to detect and quantify immunoglobulin M (IgM) antibodies in human biological samples such as serum or plasma. Commonly applied in clinical diagnostics and research settings to assess recent or acute infections, as IgM is typically the first antibody produced in response to pathogens. Helps in studying immune responses in diseases like hepatitis, HIV, dengue, and more recently, in viral infections such as COVID-19. Also used in autoimmune disease research and vaccine development to monitor early antibody production. The kit enables high-throughput analysis with high sensitivity and specificity, making it valuable in both laboratory and medical environments.
