M.pneumoniae IgM


Mycoplasma pneumoniae is a contagious bacteria that causes mild infections of the respiratory system and spreads easily and quickly in crowded areas through coughing and sneezing. Mycoplasma testing is used to find out whether someone currently has or recently had a mycoplasma infection. Mycoplasma pneumoniae IgM antibodies are involved in the very early stages of the immune response and first to be made by the body when fighting a new Mycoplasma pneumoniae infection, providing short-term protection.

What might a low result mean?

Negative results do not rule out the presence of an early Mycoplasma pneumoniae infection. The blood sample may have been drawn before the appearance of detectable antibodies. If symptoms are present and persist, a repeat test is recommended in 10 to 14 days.

What might a high result mean?

A positive IgM result indicates a current Mycoplasma pneumoniae infection.
