| Interpretive Data: |
Volume (mL) of fetomaternal hemorrhage (assuming a maternal blood volume of 5 liters) = percent fetal rbcs x50.
The quantitation of fetomaternal hemorrhage by this method is inherently imprecise. Therefore, it is important to provide a safety margin when calculating the dose of RhIG.

| Note: |
This test should be ordered on pregnant or post-partum women who need to be assessed for RhoGAM® or fetal-maternal bleeds. For routine fetal hemoglobin (Hb F) testing, please order Hemoglobin Evaluation with Reflex to Electrophoresis and/or HPLC (0050610).
