Lymphocyte proliferation in response to the nonspecific mitogens phytohemagglutinin (PHA), concanavalin A (Con A), and pokeweed are determined by 3H-thymidine incorporation.
Results are reported as counts per minute (CPM) mitogen 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.
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)
Interpretation comparing the patient results to the client normal control and the laboratory control will be provided by the medical director.
