[The Coulter counter S-plus model: accuracy and normal values in platelet count].

An evaluation of performance characteristics and accuracy of clinical results for automated multiparameter whole-blood platelet Counter Coulter Mod. S-Plus is described. Instrument precision is assessed in terms of reproducibility, linearity, carry-over. The results of all are impressive. Comparison of results with those obtained by manual reference method show excellent correlation. Normal values are defined for the platelet's parameters.
