WebJan 10, 2011 · Traditionally, the Kleihauer-Betke (K-B) assay has been the method of choice for quantifying fetomaternal hemorrhage (FMH). 1 In recent years, flow cytometric methods gradually replaced the K-B method because the K-B method has some inherent inaccuracies and drawbacks, which can largely be eliminated by flow cytometry. The … WebScreening for FMH by flow cytometry is well-correlated with the reference cytochemical technique, but it is more precise and more reproducible. The use of flow cytometry enables the systematic overestimation observed with the Kleihauer test, which could lead to excessive injection of anti-D gammaglobulins, to be avoided. This is because the ...

WebThis approach makes flow cytometry a powerful tool for detailed analysis of complex populations in a short period of time. This review covers the general principles and selected applications of flow cytometry such as immunophenotyping of peripheral blood cells, analysis of apoptosis and detection of cytokines. WebConclusions: In conclusion, flow cytometry is a useful tool for determining oxidative damage in RBCs. The RBCs of uremic patients are more susceptible to oxidative damage induced by H2O2, likely caused by diminished antioxidant defense in the RBC membrane. Successful renal transplantation leads to a normal autofluorescence response in the …

WebFetomaternal hemorrhage quantitation is usually performed by acid elution test (Kleihauer-Betke test) or hemoglobin F quantitation by flow cytometry, although other methods are available. The test is performed to determine either the appropriate dosage of RhIG in an RhD-negative mother or to diagnose and quantitate a fetomaternal hemorrhage. WebFMH QuikQuant™ is a flow cytometric method for Fetomaternal Hemorrhage (FMH) detection and quantitation. ... Flow cytometry versus Kleihauer Betke .
