Field studies performed with peripheral platelets obtained from 6 male volunteers aged 23 to 29 years revealed an extraordinary dependence of labeling efficiency on incubation time and platelet concentration after {sup 111}In-oxine platelet labeling. Since the monitoring of in vivo-platelet function in patients with thrombocytopenia may cause problems due to insufficient labeling results and homologous platelets may show a different in vivo behaviour to autologous ones, we have searched for the minimal amount of platelets necessary to allow appropriate labeling and imaging in patients with thrombocytopenia. In 15 patients with untreated thrombocytopenia aged 14 to 79 years demonstrating a mean peripheral platelet count of 2.509 +/- 1.45 x 10(4) cells/microliters autologous {sup 111}In-oxine platelet labeling was performed. The results indicate that approximately 1 x 10(8) (concentrated) platelets/ml are necessary to obtain an adequate labeling efficiency and recovery. This platelet concentration can be easily achieved by drawing one more Monovette of whole blood per each 5 x 10(4) platelets/microliter peripheral platelet count less than 2 x 10(5)/microliter. It is concluded, that calculation of the required number of platelets in advance, variation of the blood volume drawn and the volume of incubation buffer allow informative, qualitative and quantitative results using autologous platelets. The method presented effectively circumvents the requirement of homologous platelets for radiolabeling in thrombocytopenia.
