Preferred Specimen
10 mL amniotic fluid collected in a sterile, plastic, leak-proof container
Minimum Volume
10 mL amniotic fluid
10 mg chorionic villi
10 mg chorionic villi
Other Acceptable Specimens
10 mg chorionic villi collected in a sterile tube filled with sterile culture media • Cultured cells collected in each of two separate sterile T-25 flasks, 75% confluent
Instructions
Do not hold specimen; forward to laboratory when specimen arrives.
For 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.
Amniotic fluid (preferred): Normal collection procedure. Specimen stability is crucial. Store and ship at room temperature immediately. Do not refrigerate or freeze; forward to laboratory when sample arrives.
Amniocyte or Chorionic Villus (CVS) culture (acceptable): Two Specimen stability is crucial. Store and ship at room temperature immediately. Do not refrigerate or freeze; forward to laboratory when cells arrive.
Dissected Chorionic Villus (CVS) biopsy (acceptable): 10-20 mg dissected chorionic villi collected in sterile tube, filled with sterile culture medium. Specimen stability is crucial. Store and ship at room temperature immediately. Do not refrigerate or freeze; forward to laboratory when sample arrives.
