The detection of IgM antibodies is used in the early diagnosis of infectious diseases. Indirect ELISA is generally only suitable for detecting total antibodies or IgG antibodies. If the indirect method of antigen coating is used to directly determine the IgM antibody, there is generally a higher concentration of IgG antibody in the specimen, which will compete for binding to the solid phase antigen, so that a part of the IgM antibody cannot bind to the solid phase. Therefore, if anti-human IgM is used as the secondary antibody to indirectly determine the IgM antibody, the specimen must be treated with protein A or anti-IgG antibody to remove IgG interference. The capture coating method is often used in the determination of antibody IgM in clinical tests. The solid phase was first coated with anti-human IgM antibody to capture IgM in serum samples (including specific IgM antibodies against antigens and non-specific IgM). Then an antigen is added, which only binds to specific IgM. Enzymes are then added to label specific antibodies against the antigen. When interacting with the substrate, the color is positively correlated with the IgM in the specimen. This method is often used for early diagnosis of viral infections. Hepatitis A virus (HAV) antibody detection mode. Rheumatoid factor (RF) can also interfere with the capture coating method to determine IgM antibodies, resulting in false positive reactions. Therefore, the indirect method of neutralizing IgG has been favored recently, and detection of anti-CMV IgGM and anti-Toxoplasma IgM antibodies with such reagents has been successful.
