Yang, Han, Kim, Lee, and Choi: Evaluation of a Rapid Diagnostic Antigen Test Kit Ribotest Mycoplasma® for the Detection of Mycoplasma pneumoniae

Abstract

Purpose

Early detection of Mycoplasma pneumoniae is important for appropriate antimicrobial therapy in children with pneumonia. This study aimed to evaluate the diagnostic value of a rapid antigen test kit in detecting M. pneumoniae from respiratory specimens in children with lower respiratory tract infection (LRTI).

Methods

A total of 215 nasopharyngeal aspirates (NPAs) were selected from a pool of NPAs that had been obtained from children admitted for LRTI from August 2010 to August 2018. The specimens had been tested for M. pneumoniae by culture and stored at −70°C until use. Tests with Ribotest Mycoplasma® were performed and interpreted independently by two investigators who were blinded to the culture results.

Results

Among the 215 NPAs, 119 were culture positive for M. pneumoniae and 96 were culture negative. Of the culture-positive specimens, 74 (62.2%) were positive for M. pneumoniae by Ribotest Mycoplasma®, and 92 of the 96 (95.8%) culture-negative specimens were negative for M. pneumoniae by Ribotest Mycoplasma®. When culture was used as the standard test, the sensitivity and specificity of Ribotest Mycoplasma® were 62.2% and 95.8%, respectively. Additionally, the positive predictive value, negative predictive value, and overall agreement rates with Ribotest Mycoplasma® were 94.9%, 67.2%, and 77.2%, respectively.

Conclusions

A positive test result of Ribotest Mycoplasma® suggests a high likelihood of culture-positive M. pneumoniae infection. However, a negative test result should be interpreted with caution because nearly one-third of negative test results reveal culture-positive M. pneumoniae infections.
