Objective: Improve laboratory methods in testing biological activities of rHuEPO by using R-500, automated reticulocyte analyzer, instead of traditional microscopic counting method.
Methods: Testing 20 rHuEPO samples by two methods respectively.
Result: There was no significant difference between the two testing methods statistically.
Conclusion: R-500 automated reticulocyte analyze method can replace traditional microscopic counting method as an available laboratory evaluation in measuring the biological activities of rHuEPO.
