Cytokine Production by Mononuclear Cells in Response to Mitogen Stimulation, TH2 Cytokines : 0051562
[ image for: Time Sensitive]
Time Sensitive
  


Mnemonic: CYT TH2 LY

Methodology: Cell Culture/Quantitative Multiplex Bead Assay
Performed: Tue-Fri
Reported: 9-10 days
Specimen Required: Patient Prep: A control specimen needs to be sent with the patient specimen. The control specimen needs to be drawn from a normal, healthy individual who is not biologically related to the patient, and drawn at approximately the same time as and under similar conditions to the patient specimen.

Collect: Green (sodium heparin) (patient) AND green (sodium heparin) (control). Also acceptable: Yellow (ACD Solution A) (patient) AND yellow (ACD Solution A) (control). Patient and control samples must be collected within 48 hours of test performance.

Specimen Preparation: Transport 10 mL whole blood (patient) AND 10 mL whole blood (control) in original collection tubes. (Min: 7 mL whole blood (patient) AND 7 mL whole blood (control)). LIVE CELLS REQUIRED. Do not refrigerate or freeze.
Infant Minimum: 3 mL whole blood (patient) AND 7 mL whole blood (control).

Storage/Transport Temperature: CRITICAL ROOM TEMPERATURE.

Remarks:

Unacceptable Conditions: Yellow (ACD Solution B). Specimens in transport longer than 48 hours.

Stability (collection to initiation of testing): Ambient: 48 hours; Refrigerated: Unacceptable; Frozen: Unacceptable

Test Number Components Reference Interval
0051576Cytokine Production by Mononuclear Cells in Response to Mitogen Stimulation, Interleukin 4 By report
0051577Cytokine Production by Mononuclear Cells in Response to Mitogen Stimulation, Interleukin 5 By report
0051578Cytokine Production by Mononuclear Cells in Response to Mitogen Stimulation, Interleukin 10 By report
0051579Cytokine Production by Mononuclear Cells in Response to Mitogen Stimulation, Interleukin 13 By report

Interpretive Data: Phytohemagglutinin, concanavalin A, and pokeweed mitogen are tested independently in lymphocyte culture. Peripheral Blood Mononuclear Cell (PBMC) cytokine responses to these mitogens are determined by multi-analyte fluorescence detection. Results are to be used for research purposes or in attempts to understand the pathophysiology of immune, infectious, or inflammatory disorders.

Note: Results are reported as pg/mL. Interpretation comparing the patient results to the simultaneously collected client normal control and the laboratory normal control will be provided by an ARUP medical director.
