CMV infections are common and usually asymptomatic. In patients who are immunocompromised, CMV may casuse disseminated, severe disease. CMV may cause birth defects in a minority of newborns. Rapid culture provides results quickly in order to initiate therapy but may be negative in certain circumstances. Conventional culture may take more than 3 weeks.
To maintain optimun viability, place swab or fluid into VCM (equal
volume or fluid and VCM) or equivalent and transport the specimen to
the laboratory as soon as possible. Best recovery is obtained when the
specimens are refrigerated at 2-8 degrees C or kept on wet ice
following collection and while in transit. If there will be
a long delay before processing, specimens, in VCM or equivalent
should be frozen at -70 degrees C or colder and transported
on dry ice. Storage or transport at -20 degrees C is not acceptable.
Raw (unpreserved) samples should only be refrigerated
and not frozen.
Tissue must be kept moist.
PCR is preferred test for CSF and whole blood (preferred specimen:
1mL CSF submitted in a sterile, leak proof container without
transport media), 1 mL whole blood in EDTA)
