Mycoplasma pneumoniae IgM Test Cassette (Colloidal Gold) is used for qualitatively detection of Mycoplasma pneumoniae IgM antibodies in human serum, plasma (EDTA, heparin, sodium citrate) or whole blood (EDTA, heparin, sodium citrate). The test is to be used as an aid in the diagnosis of Mycoplasma pneumonia, which is caused by Mycoplasma pneumoniae. The test provides preliminary test results. Negative results do not preclude Mycoplasma pneumoniae infection and should not be used as the sole basis for patient management decisions.
