Includes

BRCA1 Sequencing, BRCA1 Deletion/Duplication, BRCA2 Sequencing, BRCA2 Deletion/Duplication, Comprehensive Interpretation

Preferred Specimen

5 mL whole blood collected in an EDTA (lavender-top) or ACD (yellow-top) tube

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

2 mL whole blood • 2 mL saliva • 1 buccal swab • 10 mg skin fibroblasts • 2 flasks 75% confluent

Other Acceptable Specimens

2 mL saliva to "fill to" line collected in OGD-500, Oragene-Dx Collection Kit or
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 collected in each of two separate sterile T25 culture flasks or equivalent with 80-100% confluent growth

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.

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.
