Specimen Required
Patient Preparation
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.  
Unacceptable Conditions
Yellow (ACD Solution B). Specimens in transport longer than 48 hours.

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.
