Potential Donor Crossmatch (Sendout)

Test Information: Initial testing includes type and screens for the potential transplant recipient and potential donor. If the potential donor is ABO compatible with the potential recipient, then a crossmatch is performed. If donor is found ABO incompatible with recipient, a crossmatch is not performed.

Ordering Requirements: Providers should complete a Bloodworks Northwest Request for Blood and Transfusion Testing requisition for each patient.

• "Recipient" or "Donor" should be specified on each request form. Enter the corresponding donor/recipient information in the designated fields.
• Potential donor and recipient samples may be submitted to Bloodworks NW separately or at the same time. Samples should be sent out as received.

Preferred: 6 mL blood in PINK TOP (EDTA) tube

• Also Accepted: 6 mL blood in LAVENDER TOP (EDTA) tube

Unacceptable: SST or GEL tubes

Dual Signatures Required:

• At the time of collection, a two-person verification of positive patient identity must be performed in the presence of the patient by the person collecting the specimen and a second qualified staff member. This includes a verbal read back of the full legal name, spelling of the legal name, and MRN as it appears in the medical record.
• Both people performing verification must sign or initial the sample label(s).
• Write the collection date and time on the sample label.
• Signatures of both verifiers are requested on the Bloodworks Northwest form. (This is not required for testing as long as dual verification is documented on the sample label.)

Store and transport whole blood at ambient temperature.

• Review the sample label(s) and requisition form for accuracy. Dual verification signatures are required on the sample label(s) only.
• Package sample(s) with the associated requisition in a biohazard bag (one patient per bag). Orders received with multiple patient samples/requisitions in the same biozard bag will be rejected by Bloodworks NW.
• Send samples as received to Bloodworks Northwest via DLMP or Delivery Express courier.
• Donor and recipient samples may be sent at the same time or separately. Do not delay transport if only one is received.
  
  • Recipient samples are held at Bloodworks for 72 hours after collection.
  • Donor samples are held at Bloodworks for 14 days after collection.
