Interpretive Data
Candida and tetanus antigens are tested independently in lymphocyte culture. Lymphocyte proliferation in response to these antigens is determined by3H-thymidine incorporation.

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

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