Performing and interpreting the bleeding time in the neonatal intensive care unit

In summary, the bleeding time is a helpful clinical tool to detect and investigate certain hemostatic defects in neonates and to evaluate the adequacy of treatments. A prolonged bleeding time alone is sometimes not sufficient to diagnose specific conditions requiring further investigations. Platelet hyporeactivity in the first days of life, gestational age, platelet dysfunction secondary to various neonatal or maternal pathologic conditions, neonatal or maternal drug administration, and hematocrit must be considered for the correct interpretation of the bleeding time test in neonates. In addition, reliable test results can be ensured only by the scrupulous execution of the procedure.
