Lymphocyte Mitogen/Antigen Stimulation (Sendout)
General Information
Lab Name
Lymphocyte Mitogen/Antigen Stimulation (Sendout)
Lab Code
RMIAGP
Epic Name
Lymphocyte Mitogen/Ag 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.

anti-CD3, Antigen stimulation, Candida Antigen Stimulation, LAB2806, LAB3317, Lymphocyte Function Analysis, Lymphocyte Transformation, MSS, PHA, Phytohemagglutinin, T Cell proliferation to Antigens, T Cell proliferation to Mitogens, Tetanus Stimulation

Ordering & Collection
Specimen Type
Collection
20 mL blood in (2) 10 mL GREEN TOP (Sodium Heparin/Na Hep) tubes
- Expedite transport to the lab. Samples must arrive at SCH Lab within 24 hours of collection.
- AM Collections: Collect Monday - Friday.
- Samples collected on a Friday must arrive in SPS by 09:00 A.M. so that samples arrive at SCH Lab with sufficient time to make the run at noon.

- Do not collect on or before holidays.
Unacceptable: Lithium heparin tubes (with or without gel)
Forms & Requisitions
Handling Instructions
Vancouver Clinic (TVC) Only:
- Expedite sample delivery to the 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.
Quantity
requested: 20 mL whole blood (NaHep)
minimum: 20 mL whole blood (NaHep)
Processing
SPS: Expedite processing. Notify Sendouts staff upon receipt of samples in the lab. Store in ambient Sendouts rack (USENDA).
Result-at-Entry:
- RMIAGR (Lymphocyte Mitogen/Antigen Requested): <Enter the specific mitogens and/or antigens requested.>

Sendouts:
- 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 processing. Send samples as received via Delivery Express courier.
- 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.
- If samples are sent close to the noon cutoff for setup, notify SCH Main Lab of incoming samples by calling 206-987-2617. Failure to do so may result in test cancellations.
Stability: Ambient: 24 hours; Refrigerated: Unacceptable; Frozen: Unacceptable.
