Human Metapneumovirus by PCR
Also known as: HMPVPCR
Use
This test is used to detect human metapneumovirus (hMPV) in children and immunocompromised adults. It is particularly useful when there is a suspicion of hMPV infection despite a negative result from a direct fluorescent antibody (DFA) test. The test helps in confirming or excluding hMPV as the causative agent of respiratory illness in these populations.
Special Instructions
Not provided.
Limitations
A negative result does not completely rule out the presence of hMPV infection, as PCR inhibitors in the sample or insufficient nucleic acid concentrations could lead to a falsely negative result. The test is qualitative, and assay performance can vary depending on the source specimen and methodological conditions.
