Test CodeCPT Codes
CPT coding is dependent on the gene requested and analyzed.
Preferred Specimen
Patient Preparation
Saliva: Do not eat, drink, smoke or chew gum for 30 minutes before collection.
Buccal swab: Please refer to user instructions provided with kit. Ensure the sponge tip does not come into contact with any surface prior to collection. Do not eat, drink, smoke, or chew gum for 30 minutes before collection. Do not touch swab tips or allow contact with any other object.
Minimum Volume
Other Acceptable Specimens
1 buccal swab submitted in OCD-100A buccal kit (ORAcollect-Dx Collection Kit) or
10 mg skin fibroblasts collected in sterile plastic container or
2 flasks skin fibroblasts, cultured amniocytes or cultured chorionic villi collected in each of two separate sterile T25 culture flasks or
10 mL amniotic fluid collected in sterile plastic leak-proof container or
10 mg chorionic villi collected in a sterile tube filled with sterile culture media
Instructions
Do not hold specimen. Forward to laboratory when specimen arrives.
Whole blood (preferred): Normal phlebotomy procedure. Specimen stability is crucial. Store and ship room temperature immediately. Do not freeze.
Saliva: 2 mL saliva collected in the Oragene-Dx collection kit up to the "fill to" line (OGD-500/OGD-600, OGD-510/OGD-610). Do not remove the plastic film from the funnel lid.
For fibroblasts and skin fibroblasts, call 1-866-GENEINFO (1-866-436-3463) prior to collecting and ordering.
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.
Amniocyte or chorionic villus (CVS) culture: 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.
Amniotic fluid: Normal collection procedure. Specimen stability is crucial. Store and ship room temperature immediately. Do not refrigerate or freeze. Forward to laboratory when sample arrives.
Dissected chorionic villus (CVS) biopsy: 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.
