Parvovirus B19 Quantitative Real-time PCR
Some specimen types for this assay are reported as qualitative results; please see our Specimen Information section below for more information.
Parvovirus B19 manifests itself as an acute or chronic hematological disorder in immunocompromised patients. It can cause persistent anemia, sometimes associated with leukopenia and thrombocytopenia. Pediatric transplant patients are at risk for chronic infections, which can be associated with lung and/or renal disorders. Quantitative DNA PCR can be used to detect the presence of the virus, track the course of infection, and monitor response to treatment.
Extraction of parvovirus B19 viral DNA from specimen followed by amplification and detection using real-time, quantitative PCR. An internal control is added to ensure the extraction was performed correctly and the PCR reaction was not inhibited. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
The primers and probes used in this assay are specific for parvovirus B19 based on similarity search algorithms. Additionally, no cross reactivity was detected when tested against adenoviruses, BKV, CMV, EBV, HSV-1, HSV-2, HHV-6 variant A, HHV-6 variant B, HHV-7, HHV-8, JCV, SV-40, and VZV.
Same day (within 8 - 12 hours from receipt of specimen), Monday through Saturday.
