Chlamydia IgA

The test relates to the serological diagnosis of genital infections. The test material is blood, in which antibodies to the pathogen are detected (chlamydia infection). Antibodies are components of the body's immune system that are produced to destroy a particular foreign protein-antigen. In this case, the antigen is Chlamydia (Chlamydia trachomatis).

There are several types of antibodies: IgA, IgD, IgE, IgG and IgM.

However, the immune system cannot cope with chlamydia even with very high concentrations of antibodies. Each of these antibodies has its own function and its own period of occurrence. IgA is produced 10-15 days after infection. The main location of IgA is the mucous membranes. To diagnose the acute stage of primary infection, it is more advisable to prescribe IgM, however, for exacerbation of the chronic course, IgA will be the best indicator.

Chlamydia infection can cause not only inflammation of the genitourinary organs but also joints, rectum, lungs, and even eyes. Methods are also used to diagnose chlamydia infection: PCR, DIF.
