An automatic blood analyser, Coulter Counter Model Sr(CC-SR) was recently introduced in our hospital. This blood analyser is able to provide simultaneous measurements of seven blood parameters, i.e. WBC, REC, Hgb, Hct, MCV, MCH, MCHC, and also produces the results within 40 seconds from aspiration of the sample into the instrument. The performance and precision of this blood analyser have been clitically evaluated by comparing the results obtained from the previous blood cell counter, the Coulter Counter Model Dn (CC-DN), a haemoglobinometer, and a high speed centfugal separator. The results are as follows: 1) The precision and liniarity for readings and dilutions on WBC, RBC, Hgb and Hct by the use of the CC-SR is satisfactory. 2) Good correlation between the measurements by whole blood analysis procedure and micro sample analysis procedure is recognized. 3) The amount of carryover from one sample to the next is negligible for practical purpose. 4) High correlation factors are obtained between the measurements by the CC-SR method and former methods: i. e. 0.99 for WBC, 0.93 for RBC, 0.99 for Hgb and 0.99 for Hct. 5) For these reason, it can be said that CC-SR is more useful successive instrument to measure WBC, RBC, Hgb, Hct than the CC-DN and other above mentioned instruments.
