Abstract
Hematological reference intervals were established by using COULTER STKS (automatic blood cell counter and cell analyzer based on flow system). For establishment of reference intervals, 529 healthy samples were obtained from 336 males and 193 females between 18 and 67 years. Sex dependent differences in the reference intervals of RBC, Hb, PCV and MCV were calculated. No sex difference was observed in the reference intervals of MCV, MCH and RDW. In the statistical treatment, adjustment by the XP-Type variable transformation was often necessary to obtain the normal distribution. Because of the strong deviation in the distribution pattern, the reference intervals for RDW, MCH, and MCHC were generated by a non-parametric (percentile) method instead of parametric method.
