Reference Interval

< 0.10 U/L: Negative
0.10-0.32 U/L: Equivocal
> 0.32 U/L: Positive

Interpretive Data

Over 50 percent 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 specimen is above 0.32 U/L and the other is below 0.20 U/L.
