This article explores emerging strategies for cost-effective universal screening of congenital cytomegalovirus (cCMV), a leading non-genetic cause of childhood hearing loss and neurodevelopmental disability. Readers will review early-life detection within the critical 21-day window, recommended specimen types—including saliva, urine, and dried blood spots—and the strengths and limitations of each. The article highlights the clinical advantages of PCR-based molecular testing and examines how sample pooling can expand access while reducing costs. Legislative momentum and evolving laboratory workflows are also discussed, underscoring practical pathways to broader, high-confidence newborn cCMV screening and earlier intervention.
LEARNING OBJECTIVES
Upon completion of this article, the reader will be able to:
- Discuss cCMV sequale and how to detect the virus in the early stages of life.
- List the various sample types for for cCMV identification and specimen of choice for screening and confirmatory testing.
- Describe the benefits of using PCR testing and sample pooling in the detection of cCMV.
- List testing methods to identify cCMV and discuss the limitations of each.
