9030. Mycoplasma pneumoniae, IgG antibodies

This test detects IgG antibodies to Mycoplasma pneumoniae, a bacterium that causes atypical respiratory infections. The presence of IgG indicates a prolonged or past infection. It has diagnostic value in adults and children with a persistent cough without significant intoxication.

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, 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, neurological damage).

IgG antibodies appear 2-3 weeks after the onset of infection; their levels peak around 4-6 weeks and can persist in the blood for months or years, indicating a long-term or past infection. In the case of reinfection, IgG levels may rise again, even in the absence of IgM. Determination of IgG has diagnostic value in combination with other classes of antibodies (IgM, IgA) and for assessing titer dynamics.

• Children and adults with prolonged or recurrent respiratory symptoms, especially those unresponsive to standard antibiotic therapy.
• As part of a comprehensive diagnostic assessment, along with IgM and IgA, to determine the disease phase.
• Children and adults with unexplained extrapulmonary manifestations that may be associated with M. pneumoniae.

• Venous blood
