Interpretive Data
Candida and tetanus antigens are tested independently in lymphocyte culture. Lymphocyte proliferation in response to these antigens is determined by 3H-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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
Note
Interpretation comparing the patient results to the client normal control and the laboratory control will be provided by the medical director.
