Specimen Collection

Special Instructions

N/A

Preferred Specimen

5 mL Whole blood collected in an EDTA (lavender-top), ACD (yellow-top), or sodium heparin (green-top) tube

Minimum Volume

3 mL whole blood • 10 mL amniotic fluid • 10 mg chorionic villi

Instructions

Do not hold specimen; forward to laboratory when specimen arrives.

Whole blood: Normal phlebotomy procedure. Specimen stability is crucial. Store and ship room temperature immediately. Do not freeze.

Note: Please indicate the ethnicity of the patient.

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 (acceptable): 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 sterile T25 flasks, 75% confluent, filled with culture medium. 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.
