Interpretive Data:


Reference Range: < 0.10 U/L: Negative 0.10-0.32 U/L: Equivocal > 0.32 U/L: Positive Interpretation: Over 50% of healthy adults have a relatively high background of specific M.pneumoniae IgG antibodies in their sera, probably due to past infections. Therefore, paired sera obtained with a time interval of 1-3 weeks are highly recommended to confirm reinfection in adults, which is demonstrated by a signficant 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.
