| Additional Information: | This test can only be performed on Rh (D) negative patients |
| | Interpretive Use: A positive test result indicates the presence of D-positive (fetal red cells) in possibly significant numbers in the maternal blood. A quantitative test (Kleihauer-Betke Test) is required to estimate the volume of feto-maternal hemorrhage as a means of estimating the dosage of Rh immune globulin needed to prevent Rh immunization. Rh immune globulin should be administered within 72 hours of birth to be effective in the prevention of Rh immunizations. |
