WebFoetal-maternal haemorrhage (FMH) is defined as the passage of foetal red blood cells into the mother’s circulatory system, either during pregnancy or at the time of delivery. Notable risk factors for FMH include abdominal injury, obstetric intervention, abortion, delivery and foetal death in utero.

WebBackground: Fetomaternal haemorrhage (FMH) assessment by the Kleihauer-Betke test (KBT) is rapid but semi-quantitative and liable to false positive results. Objectives: To compare FMH estimated by KBT with flow cytometry (FC) quantitation for 37 patients with massive FMH, obstetric risk factors or technical problems. Methods: Maternal blood was … WebThus, a reliable method to quantitatively assess FMH is necessary. Study design and methods: Serial dilutions of artificial FMH were quantitatively measured by three different methods: flow cytometry, fluorescence microscopy (each after anti-D staining), and by the Kleihauer-Betke test.
WebHemoglobin F quantitation by flow cytometry has been found to be simple, reliable, and more precise than the Kleihauer-Betke test. 82, 87 In the 2001 CAP survey, samples representing a 20-mL and a 40-mL bleed were sent as external proficiency testing. Beyond a 30-mL fetomaternal hemorrhage, a single 300-μg dose of RhIG would be insufficient to ...
