| Description: | Chlamydia trachomatis and Chlamydia pneumoniae: ELISA-VIDITEST anti-Chlamydia trachomatis kits are intended for the diagnosis of acute and chronic infections caused by Chlamydia trachomatis, i.e. inflammatory diseases of genitourinary tract in women and men, including their complications (arthritis, conjunctivitis). Anti-C.trachomatis antibody testing contributes to differential diagnosis of sexually transmitted diseases and eye infections in infants. ELISA-VIDITEST anti-Chlamydia pneumoniae kits are intended for diagnosis of infections in lower respiratory tract and eye. Primary chlamydial infection is characterized by the predominant IgM response within 2 to 4 weeks and the delayed IgG and IgA response within 6 to 8 weeks. After the acute C. pneumoniae / C. trachomatis infection IgM antibodies usually decrease and become undetectable in 2 to 6 months. IgG antibody titers decrease slowly and may persist for years. IgA antibodies tend to disappear in several weeks, but in some cases they can persist for months or years. When primary chlamydia infection is suspected, the detection of IgM is highly diagnostic. However, in recurrent or chronic infections the prevalence of IgM is low and therefore the absence of IgM does not necessarily exclude an on-going infection. For diagnosis of reinfection IgG and IgA levels rise in paired serum samples is indicative. The long time persistence of the elevated IgA antibody titers may indicate chronic infection.
