Interpretive Data

Phytohemagglutinin, concanavalin A, pokeweed mitogen, Candida antigen, and tetanus antigen are tested independently in lymphocyte culture. Lymphocyte proliferation in response to these mitogens and antigens is determined by 3H-thymidine incorporation.

Results are reported as the counts per minute (CPM) mitogen or antigen stimulated versus a control culture and a stimulation index (SI) which represents the ratio of CPM of the stimulated lymphocytes to the mean CPM of the unstimulated control.

Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Note

Interpretation comparing the patient results to the client normal control and the laboratory control will be provided by the medical director.
