Chlamydia IgA Antibody

Chlamydia IgA Antibody test is conducted to detect the IgA specific antibodies produced in response to the active Chlamydia infection – a common sexually transmitted diseases caused by bacteria Chlamydia Trachomatis. This test also aids in the identification of infertility or other disorders caused by chronic chlamydia infection. Chlamydia IgA Antibody test is an important marker to identify the active infection because the IgA antibodies exist as long as there is stimulation from Chlamydia antigens.

The reference value for the Chlamydia IgA Antibody test is <1:16. Every person with Chlamydia infection will not develop IgA Antibodies; hence, a negative result might not always indicate an absence of infection. In addition to IgA, Chlamydia IgG antibody test could be ordered by the doctor to confirm the presence of Chlamydia infection.
