Mycoplasma pneumoniae is a unique bacterium that does not always receive the attention it merits considering the number of illnesses it causes and the degree of morbidity associated with it in both children and adults. Two types of antibodies produced in response to an M. pneumoniae infection may be measured in the blood, IgM and IgG. The Mycoplasma testing is also known as Mycoplasma by PCR, Mycoplasma culture and Ureaplasma culture. The formal name of the test includes Mycoplasma pneumoniae IgG and IgM Antibodies, Mycoplasma pneumoniae Culture and Mycoplasma DNA Testing. In order to diagnose pneumoniae combination of IgG and IgM test is ordered so that the change in the amount of IgG can be evaluated and because some people, especially infants and those with compromised immune systems, may not produce expected amounts of IgG or IgM.
