Interpretive DataBackground information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
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.
Compliance Category
Laboratory Developed Test (LDT)
