9031. Mycoplasma pneumoniae, IgM antibodies

The test detects IgM antibodies to Mycoplasma pneumoniae, the causative agent of atypical respiratory infections. IgM antibodies are the first to appear in response to infection, typically appearing within 5-7 days of illness. Their presence indicates an acute phase of infection or a recent infection.

Mycoplasma pneumoniae is a bacterium that causes respiratory infections, primarily atypical pneumonia, pharyngitis, and bronchitis. It is transmitted by airborne droplets and spreads easily in organized groups (schools, families, and dormitories). School-age children, adolescents, and young adults are at risk.

The infection has a gradual onset: moderate fever, sore throat, headache, and a persistent dry cough that can persist for several weeks. Possible complications include otitis, pneumonia, sinusitis, and, in some cases, extrapulmonary manifestations (rash, arthralgia, and neurological damage).

IgM testing is most informative in cases of primary infection; in cases of recurrent infection, IgM may be absent or detectable in low concentrations.

• Adults and children with suspected atypical pneumonia, pharyngitis, or bronchitis of unknown etiology.
• For differential diagnosis between mycoplasma infection and other respiratory pathogens:
  • children and adults with unexplained extrapulmonary manifestations that may be associated with M. pneumoniae;
  • no monitor treatment effectiveness.

• Venous blood

In order to exclude factors that may affect the test results, we recommend to follow the preparation rules:
