Interpretive Data:
Over 50% of healthy adults have a relatively high background of
specific M. pneumoniae IgG antibodies in their sera, probably because
of past M. pneumoniae infections. Therefore, paired sera obtained with
a time interval of 1 to 3 weeks are highly recommended in adults to
confirm reinfection by M. pneumoniae, which is 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.
Methodology:
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
