Test Details
Methodology
Real-time polymerase chain reaction (PCR)
Result Turnaround Time
3 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
This test is intended to be used to quantitatively detect CMV DNA in urine specimens as an aid to diagnosis and management of CMV infections.
Limitations
Quantitative range is 250−1,000,000 copies/mL.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
