Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
The revision of this Standard is based on YY/T 0653-2008. Compared with YY/T
0653-2008, in addition to the editorial modifications, the main changes in this
Standard are as follows.
- modified the application scope of this Standard, changed it as "this
Standard is applicable to the hematology analyzer that analyzes physical
components in human blood and provides relative information" (see
Clause 1);
- the description in normative references is based on GB/T 1.1-2009;
- for undated reference documents, the latest versions apply to this Standard;
- the terms and definitions of accuracy, precision, linearity, carryover shall
refer to the general term definitions listed in GB/T 29791.1 (see Clause 3);
- modified the definition of hematology analyzer in the terms and definitions,
specified that it is used for the detection of human blood sample (see
Clause 3);
- modified the description in the product classification, modified 4.1 as
"analyzer with only blood cell count function", "two-group" in 4.2 as
"dichotomous", deleted all "semi-automatic, fully automatic" (see Clause
4);
- modified the provisions on atmospheric pressure in normal working
conditions as "86.0kPa ~ 106.0kPa", added a NOTE. If the conditions in
5.1.1~5.1.4 are inconsistent with the conditions stated in the manufacturer
mark, the conditions specified in the product shall prevail (see 5.1);
- modified the linearity, modified "linear deviation" as "allowed deviation
range", added the requirements for linear correlation coefficient, modified
HGB linear range (see 5.3);
- modified instrument comparability to accuracy, used fixed value fresh blood
for testing (see 5.4, 6.5);
- modified the reference range of normal blood WBC, RBC, HGB, PLT, HCT
or MCV in precision (see 5.5.1, 5.61);
- modified the accuracy test of five-classification analyzer white blood cell
classification (see 5.6.2);
