Fetal genotyping to assess risk for alloimmune thrombocytopenia. For parental or neonatal testing, refer to Platelet Antigen Genotyping Panel (3000193).
New York DOH Approval Status
Specimen Required
Amniotic fluid
OR cultured amniocytes OR cultured CVS: Two T-25 flasks at 80 percent confluency.
AND whole blood for maternal cell contamination: lavender (EDTA), pink (K2EDTA), or yellow (ACD solution A or B)
If the client is unable to culture, order test Cytogenetics Grow and Send (ARUP test code 0040182) in addition to this test and ARUP will culture upon receipt (culturing fees will apply). If you have any questions, contact ARUP's Genetics Processing at 800-522-2787 ext. 3301.
