• Expedite transport; samples must be received by Bloodworks within 72 hours of collection. Allow for an additional day of transport from UW-MT to Bloodworks Northwest.
• Submit a completed Bloodworks Northwest Eastlake Genomics Requisition along with the DLMP Requisition.* Leave the billing section blank to be completed by Sendouts staff.
  • *Use client-specific requisition when available. To obtain a client-specific requisition, contact Client Support Services via email at: commserv@uw.edu.
• WA Center for Bleeding Disorders only: A separate Bloodworks NW requisition is not required for orders submitted via interface.

Result-at-Entry:

• RDF8IS (Factor VIII Inversion DNA Sample Type): <Enter appropriate specimen type code.>
  • Specimen Type Code(s):
    • WB (Whole Blood)
    • CULAMN (Cultured Amniocytes)

Processing:

• Whole blood received at ambient temperature should be refrigerated. Ambient/refrigerated samples must be received at Bloodworks within 72 hours.*
• Whole blood received frozen should be stored frozen and transported on dry ice. WA Center for Bleeding Disorders has pre-arranged with BWNW to send samples frozen for extended specimen stability.
• If sample is collected on a Friday, notify Sendouts immediately upon sample receipt to ensure delivery to Bloodworks NW by the 1 p.m. cutoff.
• Store cultured amniocytes at ambient temperature and ship same-day.

Sendouts:

• Order Bloodworks NW Test: 3250-05.
• For orders not placed in Epic or via the ISEAWBD interface, a separate Bloodworks Northwest Eastlake Genomics requisition is required. Otherwise, send with a copy of the Epic requisition or ISEAWBD eREQ.
• Affix CAST "Billing" and "Results To" labels to the outgoing requisition.
• 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 blood orders as received with the UW DLMP or Delivery Express courier directly to the Bloodworks NW Eastlake location (do not route through BWNW Central Lab).
• Cultured amniocytes must be sent same-day to the Bloodworks Central Genomics Lab (921 Terry Ave, Seattle WA 98104).
• Samples may be sent Monday through Friday only. If sent on a Friday, samples must be in lab at the Eastlake location by 1 p.m.
• Ambient or refrigerated whole blood samples must arrive at Bloodworks within 72 hours of collection.*
