Sendouts (UW-MT/HMC) and FHCC SPS:
- Bloodworks NW HLA Test: 3084-01
- Interfaced: Yes [Interface: 603; Worksheet: UBWHLA/HBWHLA/FBWHLA or other location-specific worksheet group]
- Send sample(s) with a copy of the Bloodworks Northwest HLA Requisition or the EPIC requisition (must indicate the test or panel to be ordered at Bloodworks NW).
- 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 biohazard bag will be rejected by Bloodworks NW.
- Send routine samples via scheduled DLMP Courier pickup or Delivery Express according to the site’s preferred transportation method.
- STAT orders should be transported to Bloodworks Northwest as received.* Depending on the courier schedule, it may be necessary to individually batch a STAT order and/or call Delivery Express for pickup.
- *STAT orders for this test are rare and require the provider to request approval from the HLA Lab. If approval is obtained, the HLA Lead Technical Coordinator will contact CSS to request expedited transport of a sample. CSS will create an HC1 task for SPS. If this is not done, orders should be considered routine.
Stability: Ambient.
