Cellular mimicry in kleihauer–betke assay

Abstract

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, we propose a simple mathematical alteration to accommodate the correction for some of the factors that lead to falsely high estimation of FMH.
