title: Immature cells identified by the H-1 hematology analyzer predicts thymidine incorporation after mitogenic stimulation.
abstract: The incorporation of thymidine by lymphocytes stimulated by phytohemagglutinin (PHA) was correlated with the number of immature cells identified by the Technicon H-1 as blasts. The number of blasts and thymidine incorporation plateaued on day 3. At that time, a high linear correlation between the two variables was found (r = 0.949, p less than 0.01). The H-1 evaluated the samples in 60 seconds as compared to 3 hours of processing required to calculate thymidine incorporation. We conclude that the number of immature cells identified by the Technicon H-1 can predict the degree of thymidine incorporation after stimulation of peripheral blood cells with PHA. The H-1 may replace the more time consuming and dangerous use of radioactive thymidine incorporation in evaluating patients' functional immunologic status.
