FMH - Feto Maternal Haemorrhage

General Information

Large feto-maternal haemorrhages found by Kleihauer will be confirmed by flow cytometry. This test can only be performed by this technique if the mom and baby have differing rhesus blood groups. BCSH guidelines suggest that a foetal bleed of greater than 2ml on Kleihauer should be confirmed by flow cytometry.

Samples within HEFT will automatically be refered for FMH estimation by flow cytometry if found to be high by the Kleihauer method.

Suggested Anti-D dosage takes into account the uncertainty of measurement of FMH measured by flow cytometry in this laboratory. Click here for further information.
