UCH Clinical Laboratory - Molecular Diagnostics
One 6.0 mL pink-top (EDTA - whole blood) filled to at least 80% capacity.
Specimen SOURCE must be included on requisition.
NOTE: If testing desired on PLASMA, order LAB3244 and specify SOURCE = plasma.
At least 0.5 mL of whole blood collected in a 1.0 mL pink top microtainer (EDTA) or other blood tube with EDTA anticoagulant.
Sample not properly identified; insufficient sample volume; contaminated specimen; clotted sample; tubes not filled to 80-100% capacity; improper storage conditions; gross hemolysis; samples stored in fixatives.
Internal: Deliver to lab immediately at ambient temperature.
Offsite: Do not centrifuge. Send at 2-8 degrees C if tested within 72 hours. If delivery is not expected within 72 hours, freeze whole blood at -70 degrees C and ship on dry ice.
Ambient, 12 hours; Refrigerated, 72 hours, Frozen (-70 degrees C), 6 months.
DNA amplification by polymerase chain reaction (PCR) using a CMV-specific DNA probe detected by real-time PCR.
0 = Not Detected
<1000 = Positive. Virus detected below 1000 IU/mL
1000-1,000,000 IU/mL = Quantitative positive range
>1,000,000 IU/mL = Greater than maximum quantitative range.
