Dual colour flow cytometric test for FMH in RCI
From 9 October 2017 RCI will be using a new dual colour reagent for flow cytometric measurement of fetomaternal haemorrhage.
The reagent includes a phycoerythrin conjugated antibody which will allow the exclusion of white cells from the counted population.
This will improve accuracy, and in particular reduce the effect of high background counts encountered when testing samples from some patients.
This will not change the content or format of the reports on these cases.
