Mycoplasma infection of the genitourinary system. Antibodies to Mycoplasma hominis in blood serum
Using ELISA, it is possible to determine IgM and IgG antibodies to Mycoplasma hominis. This method is more sensitive and specific (92% and 95%, respectively) than others. IgM and IgG antibody titers should be determined during the acute period of the disease and after 2-4 weeks. IgM antibodies appear during the first week of the disease and disappear after recovery, but in some cases they can remain in the blood for up to 1 year. The content of IgG antibodies begins to increase somewhat later than IgM, but remains elevated longer. An IgG titer higher than 1:10 and/or a 4-fold increase in the IgG-AT titer in paired sera indicate a current infection.
