FMH Estimation — HaemBase

WebJan 5, 2002 · Flow cytometry for the estimation of FMH is an evolving technique and offers the advantage that if an anti-D reagent is used to relabel the fetal cells, RhD-positive cells are detected. It is recognized that not all laboratories have access to a flow cytometer and that in many laboratories only the acid elution technique is available. 8. WebThe precision of the method is mediocre (CV: 30–40%), and a systematic overestimation of the extent of the FMH has been shown with this technique (reference 2). Screening for FMH by flow cytometry is well-correlated with the reference cytochemical technique, but it is more precise and more reproducible. how does avast make money
