Parvovirus B19 by Qualitative PCR
Also known as: PARVPCR
Use
The Parvovirus B19 by Qualitative PCR test is a nucleic acid amplification test used to detect the presence of Parvovirus B19 DNA in patient samples. It is primarily employed to assist in the diagnosis of Parvovirus B19 infections, especially in cases where it is crucial to differentiate between low-level viral persistence and active infection. This test is particularly useful for monitoring the response to treatment and predicting relapse in immunocompromised patients.
Special Instructions
Not provided.
Limitations
This test is designed to qualitatively detect the presence of Parvovirus B19; it is not suitable for determining viral load. A negative result does not rule out the presence of PCR inhibitors or the presence of Parvovirus B19 in concentrations below the detection level of the assay. It has not been cleared or approved by the FDA, but is developed and its performance characteristics determined by ARUP Laboratories under a CLIA certification for clinical use.
