Comments: |
Specimen contaminated with red cells will be tested to determine if they are fetal or adult. Visibly bloody specimen will be examined for fetal RBCs by Kleihauer-Betke technique or fetal Hgb methods. Amniotic fluid specimen contaminated with fetal blood may exhibit abnormally high AFP values. Patients with an amniotic fluid AFP ≥ 2 MOM are at increased risk for a neural tube defect or ventral wall defect and should have amniotic fluid acetylcholinesterase determined. The ordering physician will be notified of the abnormal results and a request for acetylcholinesterase can be made at that time. |
