The use of saliva as a practical and feasible alternative to urine in large-scale screening for congenital cytomegalovirus infection increasesinclusion and detection rates

Authorship SCIMAGO INSTITUTIONS RANKINGS

INTRODUCTION:

Although urine is considered the gold-standard material for the detection of congenital cytomegalovirus (CMV) infection, it can be difficult to obtain in newborns. The aim of this study was to compare the efficiency of detection of congenital CMV infection in saliva and urine samples.

METHODS:

One thousand newborns were included in the study. Congenital cytomegalovirus deoxyribonucleic acid (DNA) was detected by polymerase chain reaction (PCR).

RESULTS:

Saliva samples were obtained from all the newborns, whereas urine collection was successful in only 333 cases. There was no statistically significant difference between the use of saliva alone or saliva and urine collected simultaneously for the detection of CMV infection.

CONCLUSIONS:

Saliva samples can be used in large-scale neonatal screening for CMV infection.
