Storage/Transport Temperature
Storage:
Room temperature for 4 hours
Refrigerator temperature for 0-72 hours
Performed
Hematology. Daily, routine and STAT. STAT requests are honored until 2100.
Remarks
The Kleihauer-Betke test is done to determine the amount of fetal blood or transplacental hemorrhage (TPH) present in a mother's circulation. TPH can be present after a baby's delivery. This is of main concern in Rh antigen negative mothers. The presence of fetal blood positive for the Rh antigen can immunize an Rh negative mother to the Rh antigen. Knowing the amount of TPH present is used to determine the correct prophylactic dose of the immunoglobulin (RhoGAM) to be administered to the mother to protect her from Rh immunization. TPH can also be present after some sort of trauma to the mother or fetus. An example of this could be a "traumatic amniocentisis" where the placenta may have been accidentally nicked and fetal blood has leaked into the mother's circulation or amniotic fluid. Trauma can be of concern in both Rh positive and Rh negative mothers.
Notes
Test determines % fetal cells.
Patient’s height and weight should be provided. These parameters enable more accurate calculation of the volume of fetomaternal bleeding as well as the number of vials of Rh immune globulin to administer to an Rh-negative woman. If the weight &/or height are not given, only the volume of the bleed will be reported. This better serves the patient by allowing for individual determination of the amount of Rh immune globulin to administer. Questions concerning dosage calculations may be directed to the pathology resident on-call (pager 888-1317 or 888-1380) or Dr. Scott Koepsell (pager 888-0374).
