Completed Prenatal Genetic Test Requisition Form is required. This test is intended for amniotic fluid samples without chromosome analysis order that need to be cultured for other cytogenetic/molecular genetic/biochemical testing (e.g. prenatal microarray analysis, DNA isolation and storage, send-out testing) or cryopreservation for future testing. If additional in-house or send-out testing on cultured fibroblasts is desired, please clearly indicate the desired testing on the lab order and call the Cytogenetics lab (614-722-5321) and speak to a laboratory genetic counselor to coordinate additional testing. Otherwise, cultured cells will be cryopreserved for future testing. If cultured amniocytes will be used to perform fetal molecular genetic testing, submission of maternal blood sample in EDTA tube is highly recommended to perform maternal cell contamintation study.
