EDTA Peripheral blood or plasma

Minimum volume:
0.5 mL

Storage and stability information:
Peripheral blood (Refrigerated, 1 week), Plasma (Refrigerated or frozen at -20°C, 1 week)

Test performed:
Once per week

CMV DNA not detected

Clinical significance:
Infection with cytomegalovirus (CMV) is a significant cause of morbidity and mortality in transplant recipients and other immunocompromised hosts, as well as neonates. Infection may involve multiple organs including the brain, lung, liver, and gastrointestinal tract. In plasma, the detection of CMV is more indicative of an active CMV infection. Assays performed on whole blood can potentially detect latent virus.
