Özet
Aims: The rapid antigen detection test and throat culture can be used for the diagnosis of group A beta hemolytic streptococcus (GABHS) infections. The aim of this study was to determine the sensitivity and specificity ratios of the rapid antigen test for GABHS in the laboratory setting. Materials and methods: In this study, the throat culture and rapid antigen test results were evaluated for 5120 patients between the ages of 0-18 years, who were admitted between January and June 2014 to the pediatric outpatient clinic with a diagnosis of clinical exudative tonsillopharyngitis. The tests of these patients were performed at the microbiology laboratory of Turgut Ozal University Hospital. Patients with only a throat culture or a rapid antigen test result were excluded from the study. Thus, 1243 patients were included in the current study, in which both tests had been performed. Two throat swab samples were collected from these patients. Culture tests and rapid antigen tests were both performed for the patient samples. The Strep A Abon kit [Hangzhou, China] was used as the rapid antigen test. Results: Nine hundred thirty-six patients had no bacterial growth in their throat cultures, while 307 throat cultures were positive for GABHS. The sensitivity and specificity of the rapid antigen test were 73% and 96.8%, respectively. The positive and negative predictive values for the rapid. antigen test were 88.2% and 91.6%, respectively. Conclusion: Although the specificity of the rapid antigen test used in this study Was high (96.8%), its sensitivity was determined to be lower (73%). Therefore, for patients in whom negative test results are obtained, it would be appropriate to confirm the test results with throat cultures.
