MYCOPLASMA PNEUMONIAE ANTIBODY IgM
Specimen Collection Requirements
One 4 mL serum separator tube.
Separate serum from cells ASAP. Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Please mark specimen plainly as "acute" or "convalescent."
Refrigerate serum at 2-8°C. Submit specimen in Tube.
Severely lipemic, contaminated, heat-inactivated, icteric or hemolyzed specimens.
After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
0.76 U/L or less: Negative - No clinically significant amount of M. pneumoniae IgM antibody detected.
0.77-0.95 U/L: Low Positive - M. pneumoniae-specific IgM presumptively detected. Collection of a follow-up sample in one to two weeks is recommended to assure reactivity.
0.96 U/L or greater: Positive - Highly significant amount of M. pneumoniae-specific IgM antibody detected. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
