Parvovirus B19 by Quantitative PCR
Also known as: PARV QNT
Use
This test is used to diagnose and monitor human parvovirus infection in patients with a suppressed or delayed immune response. It quantitatively measures the viral load of Parvovirus B19 using PCR to assist in clinical management and evaluation of the viral infection.
Special Instructions
Specimen source is required for processing. The test is performed on specific days (Mon, Wed, Fri), and it is important to ensure specimens are collected and processed according to guidelines.
Limitations
The test has a quantitative range of 2.0-8.0 log IU/mL (100-100,000,000 IU/mL). A negative result does not rule out the presence of PCR inhibitors or Parvovirus DNA concentrations below the detectable level. Inhibition may lead to underestimation of viral quantitation.
