Abstract:

Objective To verify the applicability of the newly-issued Blood Cell Analysis Reference Interval industry standard WS/T405—2012 for healthy adults in Xuzhou. Methods According to WS/T405—2012 issued by the National Health and Family Planning Commission of the People's Republic of China in December 2012,9 004 healthy adults aged from 20 to 79 in Xuzhou were enrolled,and their venous blood samples were collected. Blood routine test was performed by XT-4000 blood cell analyzer. The individual distribution for those beyond the new reference intervals about 11 white blood cell（WBC） indices [WBC count,neutrophil value（NEUT#）,lymphocyte value（LYMPH#）,monocyte value（MO#）,eosinophil value（EO#）,basophil value（BASO#）,neutrophil percent（NEUT%）,lymphocyte percent（LYMPH%）,monocyte percent（MO%）,eosinophil percent（EO%） and basophil percent（BASO%）] listed in industry standard was analyzed. The difference of indices for sex and age was analyzed statistically. Results The individual proportions of all the WBC indices beyond the new reference intervals were <10%. Except BASO# and BASO%,the other 9 indices had statistical significance between males and females（P<0.05）. Conclusions The new reference intervals of WBC and related indices are suitable in Xuzhou,without considering sex and age.
