IDWeek Commentary | Dr. Hongmei Xu: CMV PCR Agreement between Blood and Dried Blood Spots in Infants with Congenital Cytomegalovirus Infection
Infants can be infected with congenital cytomegalovirus (CMV) through vertical mother-to-child transmission, and CMV infection screening is required for some newborns with specific indications. Polymerase chain reaction (PCR) is a commonly used clinical method for qualitative or quantitative diagnosis of CMV, and it can test specimens such as urine, plasma, and dried blood spots, each with its own advantages and disadvantages. A recent study evaluating the consistency of plasma PCR and dried blood spot PCR for CMV infection diagnosis was presented at the 2023 IDWeek. Dr. Hongmei Xu from Children's Hospital of Chongqing Medical University introduces and comments on this study.
