Congenital Adrenal Hyperplasia (CAH) 21-Hydroxylase Gene Sequencing
MessageCollect 1 of the samples below: Blood: Collect a full tube, following standard venipuncture techniques. Specimen stability is crucial. Store and ship ambient immediately. Do not freeze. Amniotic fluid: 10 mL collected in a sterile, leak-proof container . Specimen stability is crucial. Store and ship ambient immediately. Do not refrigerate or freezeFor fetal testing: 1) Please call 1-866-GENE-INFO (1-866-436-3463) prior to submission. 2) Documentation of parental carrier status must be provided. 3) It is required that Maternal Cell Contamination Study, STR Analysis be ordered in conjunction with fetal testing. A separate tube of maternal blood (EDTA) is required for this test.
