The mean The Kleihauer-Betke test (KB) is among the earliest volume of FMH in the remaining 18 (22.5%) cases by KB was 8.3 ± 1.7 mL. Fifteen (83.3%) of these 18 cases had FMH of at least methods developed for FMH quantification and is still widely 0.4 percent (approximately 8 mL) by gel technology.
Blood was taken from 100 consecutive asymptomatic women at 17 to 18 weeks of pregnancy for Kleihauer testing. When a proportion of these slides were assessed at a different hospital there was agreement in only 46%. When the number of fetal cells were
The Kleihauer–Betke (KB) test is a time‑consuming test with a lot of variables which affect the calculation of the extent of fetomaternal hemorrhage (FMH). There have been several formulae proposed by various authors to calculate FMH using KB test. In this article
Background This study aimed to assess fetomaternal hemorrhage (FMH) among RhD negative pregnant mothers using two techniques, Kleihauer-Betke (KBT) and Flow cytometry (FCM). To determine if patient-specific doses of prophylactic anti-D warrant further investigation in Ethiopia and wider Africa. Methods Hospital- based cross-sectional study was conducted among 75 RhD negative pregnant …

Subsequent Kleihauer-Betke testing showed 3.6% of fetal RBCs, indicating approximately 180 mL of fetal-maternal bleeding. By calculation, this requires a total of seven vials of Rh immune globulin (RhIG) to prevent Rh(D)-antigen alloimmunization. The patient
· PDF 檔案According to Oski and Naiman (8) the Kleihauer-Betke staining procedure is capable of detecting as little as 0.1 ml of fetal blood in maternal circulation. 7 2 7 CALCULATION AND RESULTS
The Kleihauer Betke test relies on the principle that red cells containing fetal hemoglobin (HbF) are less susceptible to acid elution than cells containing HbA. A thin smear of maternal blood is exposed to citric acid phosphate buffer (pH 3.2), which elutes hemoglobin from …
Calculation of dose:- by Kleihauer Betke test/Acid Elution Test • Performed on maternal blood to assess amount of fetomaternal bleed • Principle- HbF is more resistant to acid elution than HbA • No. of fetal red cells in 50 low power fields is assessed • 80 cells in

Kleihauer-Betke test: The Kleihauer-Betke test is used to determine the amount of feto-maternal hemorrhage (FMH), the amount of fetal blood that has crossed into the mother. The test uses an acid elution method that removes adult hemoglobin but not fetal hemoglobin.
