General Information

Lab Name

Lymphocyte Mitogen/Antigen Stimulation (Sendout)

Lab Code

RMIAGP

Epic Name

Lymphocyte Mitogen/Antigen Stimulation (Sendout)

External Test Id

LAB3317, LAB2806

Description

Description:

  • The Mitogen Stimulation Study is used in the evaluation of immunodeficiency to determine the functional capabilities of peripheral blood mononuclear cells to respond to non-specific stimuli (PHA and/or anti-CD3).
  • The Antigen Stimulation Study is used in the evaluation of immunodeficiency to determine the functional capabilities of peripheral blood mononuclear cells to respond to specific stimuli (Tetanus and/or Candida).

    Ordering Requirements: Provider must specify which mitogens (PHA, CD3) and/or antigens (Tetanus, Candida) are required. Failure to do so may result in significant delays or cancellations.

      Collection Note: Limited specimen stability. Time blood collections accordingly to ensure that samples reach the performing lab within the 24-hour stability limit.

      Ordering & Collection

      Specimen Type

      Blood

      Collection

      Collection: 20 mL blood in (2) 10 mL GREEN TOP (Sodium Heparin/Na Hep) tubes

      • Unacceptable: Lithium heparin tubes (with or without gel)

      Collection Timing:

      • AM Collections: Collect Monday - Friday. Samples collected on a Friday must arrive in SPS by 09:00 A.M. to ensure sufficient time to make the noon run at Seattle Children's.
      • PM collections: Collect Monday - Thursday only. Orders collected late morning or afternoon on Fridays will be cancelled.
      • Do not collect on or before holidays.

      Expedite transport to the lab. Samples must arrive at SCH Lab within 24 hours of collection.

      Forms & Requisitions

      Handling Instructions

      Vancouver Clinic (TVC) Only:

      • Expedite transport to the UW Central Lab to ensure that the samples arrive at Seattle Children's lab within the 24-hour stability.
      • Include the mitogen(s) and/or antigen(s) requested for each order (PHA, CD3, Tetanus, Candida). Failure to provide this information may result in delays or cancellations.

      Other Outside Laboratories: Due to the limited sample stability for this test, clients should arrange for testing directly with Seattle Children's Hospital Laboratory.

        Stability: Ambient: 24 hours; Refrigerated: Unacceptable; Frozen: Unacceptable.

        Quantity

        requested: 20 mL whole blood (NaHep)
        minimum: 20 mL whole blood (NaHep)

        Processing

        SPS: Short stability; expedite processing. Notify Sendouts staff upon receipt of samples in the lab. Store samples in the ambient Sendouts rack at each site (USENDA/HSENDA/CSENDA).

          Result-at-Entry:

          • RMIAGR (Lymphocyte Mitogen/Antigen Requested): <If not filed from Epic, enter the specific mitogens and/or antigens requested from the table below.>

          Mitogens/Antigens Available:

          Mitogen PHA
          Mitogen CD3
          Antigen Tetanus
          Antigen Candida

          Sendouts (UW-MT or HMC)/Central Lab (RCLSPS):

          • SEACHL Tests:
            • LAB3317 (Mitogen Stimulation Study)
            • LAB2806 (Antigen Stimulation Study)
          • Review the Epic order or TVC manifest to confirm which mitogens and/or antigens are being requested. Complete the SEACHL Cell Marker Requisition accordingly.
          • Expedite transport. Send samples as received via scheduled DLMP Courier pickups or Delivery Express according to the site’s preferred transportation method.
            • AM Collections: Must be sent out same day and arrive in SCH Lab by noon for same-day setup.
            • PM Collections: May be held at room temperature for sendout the following morning. Must arrive at SCH Lab by noon for setup.
          • Samples drawn on Friday must be received at SCH lab by noon.
          • Notify SCH Cell Marker Lab at 206-987-2560 if sending a sample nearing the stability limit or Friday noon cutoff.

          Stability: Ambient: 24 hours; Refrigerated: Unacceptable; Frozen: Unacceptable.
