In these studies, the DF32P leukokinetic technique has been modified so that neutrophil kinetics may be studied in the nonsteady state. In order to achieve this modification, an acid citrate solution was used in preparing leukocytes for radioactive assay. This results in a suspension free of cell agglutination so that a specific activity related only to neutrophils is obtained. This technique has been successfully employed in the study of the early phase of cortisol-induced granulocytosis, allowing measurement of cell flow rate in and out of the circulating granulocyte pool. This method is also useful in the study of subjects with pronounced neutropenia.
