RSV DETECTION TEST
Becton Dickinson Microbiology Systems announces Directigen® RSV1 the first "stat" test for the qualitative detection of antigen to respiratory syncytial virus (RSV). An in vitro enzyme immunoassay membrane test, Directigen RSV is performed directly on nasopharyngeal specimens. Cumulative results of independent studies of 281 specimens have demonstrated that Directigen RSV achieves 97% sensitivity and 98% specificity when compared with tissue cultures. All components of Directigen RSV are stored at room temperature, thus making the test available immediately without waiting for warm reagents.
The test takes less than 15 minutes to perform and read, allowing for quick confirmation of antiviral therapy recommendations. Antigen from infected cells is extracted from the specimen using the DispensTube™; color development takes place in the ColorPAC™ triangular testing device. When RSV antigen is present, the familiar CoíorPAC triangle is seen. When negative, a solid dot appears. The clear triangle and dot minimize subjective interpretation.
To assure reliability every ColorPAC test device includes built-in procedural quality controls, indicating that reagents are active and the test was performed correctly.
