Test Code CCMVS Congenital Cytomegalovirus (cCMV), Molecular Detection, PCR, Saliva


Ordering Guidance


This test should be ordered to test saliva specimens from patients 21 days old or younger. To test saliva from patients older than 21 days, order CMVPV / Cytomegalovirus (CMV) Molecular Detection, PCR, Varies.

 

To test urine specimens from patients 21 days or younger, order CCMVU / Congenital Cytomegalovirus (cCMV), Molecular Detection, PCR, Urine. To test urine from patients older than 21 days, order CMVPV / Cytomegalovirus (CMV) Molecular Detection, PCR, Varies.

 

For CMV testing on plasma specimens, order CMVQN / Cytomegalovirus (CMV) DNA Detection and Quantification by Real-Time PCR, Plasma.
