However, fetal maternal hemorrhage was considered the cause of death in only 1.3% of cases because, beyond a positive Kleihauer-Betke test, evidence of fetal anemia confirmed by placental examination and / or autopsy was required for hemorrhage to be considered the cause of death (AmJ Obstet Gynecol.
Likewise, increases in fetal hemoglobin percentage in adults with disease states such as thalassemias are fairly common, and hereditary states of persistence of fetal hemoglobin in adult life are described, which could also (rarely) confound a Kleihauer-Betke test. For these reasons, a flow cytometric test offers a more reliable, reproducible, and superior metric, but is not yet widely employed and not available at the point of care.
