After amniocentesis, 5-20% of patients have evidence of fetal-maternal hemorrhage as indicated by increases in maternal serum [alpha]-fetoprotein (1-5) or by the Betke-Kleihauer test (6-8).
The Betke-Kleihauer test and flow cytometry are widely used, but these tests have limited ability to detect fetal-maternal hemorrhage because of the rarity of fetal cells in the maternal circulation (10).
