Abstract:
Objective To verify the linear range of WBC measured by CD3700 hematocyte counter. Methods The high-valued specimen was prepared with the enriched white coat,and diluted as a series of concentrations of specimens with the physiological saline. Every specimen was measured for twice,and the sequence of specimens was random. And the Grubbsper test, polynomial regression anal-ysis,and random error estimation were performed. Results There is no outlier in the test results. Re-gression analysis showed it displayed linear in the range of 0 to 219 × 109/L,and the random error was within the allowable limit of our laboratory. Conclusion The linear range of WBC measured by CD3700 hematoeyte counter is coincident to what the manufacturer claims.
