Monday, Sept. 2, is Labor Day. Our lab and all support services will be closed. Kit orders placed on Sept. 2 will be sent on Sept. 3, and all in-transit patient samples will be held by the carrier and received on Sept. 3. If you need assistance, please leave a message at 888-729-1206 or Support@GeneDx.com and we will respond when we return on Sept. 3.
Exceptions
Dried blood spots (DBS) are not accepted if the patient has ever received an allogeneic bone marrow/stem cell transplant. For these patients, DNA from cultured fibroblasts is the required specimen type. GeneDx can provide a punch biopsy kit and can culture fibroblasts on site, as needed.
Volume
For best results, send 8 spots per person, of 10mm diameter, completely filled. If 8 spots are not available, send as many as possible to reduce the chance of incomplete or delayed results. Minimum 2.
Labeling
Label with the patient name plus a second identifier such as date of birth, specimen ID or medical record number. Name and 2nd identifier on the specimen label must match what is on the test order.
Stability
The blood on the DBS cards should dry at room temperature for at least 3 hours after collection.
Rejection
Dried blood spots will be rejected if submitted for any test for which DBS is not listed as an alternative specimen, if there is insufficient volume, or if the patient has had an allogeneic bone marrow transplant.
Shipping
Ideal handling is to ship immediately, after drying, for overnight delivery with arrival Monday-Saturday:
