157 EDTA blood samples from thrombocytopenic patients (platelets less than 100 X 10(9)/1) were measured and the platelet counts compared using the various blood cell counters of the central laboratory, University Clinic, Göttingen. Using the H 6000, Hemalog 8 (both Technicon) and ELT-8 (Ortho Instruments), product-moment correlation coefficients (r) ranging from 0.88 to 0.92 were obtained between the different counters. The correlation coefficients of the thrombocounter (Coulter) to the other instruments were only 0.84 and 0.85. Discrepant platelet counts (difference greater than 40 X 10(9)/1) were reinvestigated using the Neubauer chamber. From a total of 354 platelet measurements, falsely high concentrations were observed only in three cases and falsely low concentrations in seven cases.
对157例血小板减少症患者（血小板计数低于100×10⁹/L）的乙二胺四乙酸（EDTA）抗凝血样进行检测，并使用哥廷根大学诊所中心实验室的各种血细胞计数器对血小板计数进行比较。使用H 6000、Hemalog 8（均为Technicon公司产品）和ELT - 8（Ortho仪器公司产品），不同计数器之间的积差相关系数（r）在0.88至0.92之间。血栓计数器（库尔特公司产品）与其他仪器的相关系数仅为0.84和0.85。对有差异的血小板计数（差值大于40×10⁹/L）使用Neubauer血细胞计数板重新检测。在总共354次血小板测量中，仅3例观察到血小板浓度假性升高，7例观察到血小板浓度假性降低。
