CMV by PCR
Use
This test employs real-time PCR amplification of a Cytomegalovirus-specific conserved genetic target. It is used to detect Cytomegalovirus DNA in amniotic fluid. A positive result should be coupled with clinical indicators for diagnosis. It's crucial in managing patients suspected of having a Cytomegalovirus infection, particularly in prenatal screening to assess potential risk to the fetus.
Special Instructions
The test requires exactly 1 mL of amniotic fluid which must be shipped frozen. Non-sterile or leaking containers, improperly identified specimens, insufficient sample volume, or contaminated specimens will be rejected.
Limitations
A "Not detected" result for this assay does not exclude Cytomegalovirus involvement in a disease process. The results should be interpreted alongside clinical findings, patient history, and other diagnostic information. The test detects DNA, which may not correlate with the presence of live virus.
