If the patient is Rh (-) a Fetal Screen Test should be initially ordered. A Kleihauer-Betke will automatically be reflexed and run on all positive fetal screens.
The Kleihauer-Betke (KB) test is designed to quantitate fetal red blood cells, but the results have been shown to be imprecise with a large coefficient of variation (CV). It is often utilized to quantitate large fetomaternal hemorrhages at the time of delivery in Rh (-) women for appropriate dosing of RhIG to prevent Rh alloimmunization. Although it can be used during pregnancy in both Rh (-) and Rh (+) women to detect fetomaternal hemorrhage, the evidence to support its utility are limited and results should be interpreted with caution.
