MessageCollect 1 of the samples below: Whole Blood or Bone marrow: Collect a full tube, following standard venipuncture techniques. Collected in an EDTA (lavender-top), EDTA (royal blue-top), ACD (yellow-top) or sodium heparin (green-top) tube. Specimen stability is crucial. Store and ship room temperature immediately. Do not freeze. Amniotic fluid: 10 mL collected in a sterile, leak-proof container . Specimen stability is crucial. Store and ship at room temperature 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.
