Test Performed at or Referral Lab Lab Sendouts  (ARUP)
Referral Lab number:96043 (LMP)


Reference Range:By report.
Use: 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 the counts per minute (CPM) mitogen stimulated versus a control culture and a stimulation index (SI) which represents the ratio of mean CPM of the stimulated lymphocytes to the mean CPM of the unstimulated control.
