Cytomegalovirus DNA, Qualitative

Overview

  • EPIC Code:
  • LAB2948
  • Soft Test Code:
  • CMVQL
  • Send Out Test Code:
  • 10601
Alternate Names
  • CMV DNA, Qualitative
  • CMV Qual PCR-Newborn
  • Cytomegalovirus DNA, Qualitative Real-Time PCR
Clinical Significance

CMV infections are common and usually asymptomatic. In patients who are immunocompromised, CMV may cause
disseminated, severe disease. CMV may cause birth defects in a minority of infected newborns. DNA methods provide the highest sensitivity and specificity of any method.
