Lab Code

Epic Name
HLA Antibody Monitoring DSA, STAT (Sendout)
External Test Id
3083-18
Description

Indications: Solid organ transplant.

    Test Information: The purpose of this test is to monitor patients after transplant for the presence and level of antibodies to the donor’s HLA antigens. The test is semi-quantitative.

      Ordering Guidance: This test is appropriate when results will be used to evaluate treatment options, or when results are needed overnight or over the weekend. STAT testing includes a 6-hour turnaround time with verbal result reporting. If this is not required, select alternate test options HLA Antibody Monitoring DSA, Routine (Sendout) [RHLAM] or HLA Antibody Monitoring DSA, Protocol (Sendout) [RHLAMP], as appropriate.

        Ordering Requirements:

        • Providers must notify Bloodworks Northwest HLA Laboratory of any STAT requests by calling (206) 817-7730. If this is not done, the lab will perform the test as routine.
        • Contact information is required for verbal result reporting. Include the name and phone/pager of the person receiving results in the Epic order.

        Forms & Requisitions
        Handling Instructions

        Outside Laboratories: To prevent testing delays, it is recommended that STAT orders are sent directly to Bloodworks Northwest. If sending through UW-MT:

        • Transport whole blood samples at room temperature (serum from a red top tube is also accepted). Samples must be received by Bloodworks Northwest within 10 days of collection.
        • A completed Bloodworks Northwest Immunogenetics/HLA Requisition must accompany all orders. In the Billing section, indicate "Bill to UWMC DLMP."
        Quantity
        Requested: 7-10 mL blood in red top tube
        Minimum: 2 mL blood in red top tube

        Processing

        Receiving Instructions

        Store and transport whole blood samples at ambient temperature.

        Sendouts:

        • Bloodworks NW HLA Test: 3083-18
        • 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.
        • STAT orders should be transported to Bloodworks Northwest as received. Depending on the DLMP courier schedule, it may be necessary to individually batch a STAT order and/or call Delivery Express for pickup.

        Stability: Ambient: 10 days. Serum is also accepted.
