Methodology
This test utilizes a reverse transcriptase real-time PCR procedure to detect type-specific areas within the HN gene of human parainfluenza. The analytical sensitivity of this assay is 200 copies/mL. A "Not detected" result does not rule out infection.
This test uses commercial reagents that have not been approved or cleared by the FDA. The FDA has determined that such clearance or approval is not necessary. The performance characteristics of this procedure were determined by Warde Medical Laboratory. This test is performed pursuant to a license agreement with Roche Molecular Systems, Inc.
