Polymerase Chain Reaction (PCR)
Detection of Cytomegalovirus DNA in BAL, bronchial washings or tracheal aspirate specimens.
Cytomegalovirus DNA not detected.
A single assay result should not be used as the only criteria to form a clinical conclusion. Results should be correlated with serologic test results, patient symptoms and clinical presentation.
- CMV DNA by PCR, Qualitative
Collect bronchial alveolar lavage (BAL), bronchial washings, or tracheal aspirate specimen in a sterile container. Refrigerate for up to 5 days or freeze for longer storage. Do not allow frozen specimens to thaw at any time during storage or transport, due to possible degradation of the DNA. Specimens submitted in polystyrene tubes are not acceptable. Specimens sent for Microbiology molecular testing require a dedicated sample and cannot be shared with other laboratories.
