Mycoplasma pneumoniae Antibodies, IgG & IgM
Also known as: MYCO PAN
Use
The test aids in the diagnosis of Mycoplasma pneumoniae infection in patients with persistent pneumonia, particularly when it is outside of the expected acute phase. It measures the levels of IgG and IgM antibodies against Mycoplasma pneumoniae, providing insight into both acute and past infections. Elevated levels of these antibodies can indicate an active or recent infection.
Special Instructions
Parallel testing is preferred, and convalescent specimens must be received within 30 days of receipt of the acute specimens. Mark the specimens clearly as 'acute' or 'convalescent' to ensure appropriate test processing.
Limitations
The test may not detect all infected patients as low levels of IgM antibodies can persist for over 12 months post-infection. In adults, paired sera obtained with a time interval of 1 to 3 weeks are highly recommended to confirm reinfection, demonstrated by a significant change in IgG antibodies. A significant change is indicated if one sample is above 0.32 U/L and the other is below 0.20 U/L.
