Hematology analyzer
1 Scope
This Standard specifies the terms and definitions, classification, requirements, test
methods, labels and instructions, packaging, transportation and storage of hematology
This Standard applies to hematology analyzers (hereinafter referred to as analyzers),
which qualitatively and quantitatively analyze the tangible components in human blood
and provide relevant information.
This standard does not apply to reticulocyte analyzers.

3 Terms and definitions
The following terms and definitions apply to this Standard.
[JJF 1001-1998, definition 5.6]
The proportional correlation between the states of two sets of measured values or
between the measured values obtained by two methods.
The amount of analyte discontinuity of one measurement system carrying one
measurement sample reaction to another measurement reaction sample, thereby
erroneously affecting the expression quantity of the other detection sample.
4 Product classification
4.1 The hematology analyzer without white blood cell grouping function.
4.2 Two-grouping hematology analyzer. semi-automatic hematology analyzer capable
of dividing the white blood cells into large and small groups.
4.3 Three-grouping hematology analyzer. automatic hematology analyzer capable of
dividing the white blood cells into large, medium and small groups.
4.4 Five-classifying hematology analyzer. automatic hematology analyzer capable of
classifying the white blood cells into five categories (neutrophils, lymphocytes,
monocytes, eosinophils, basophils).
5 Technical requirements
5.1 Normal working conditions
5.1.1 Power supply voltage. 220 V ± 22 V; 50 Hz ± 1 Hz.
5.1.2 Ambient temperature. 18 °C ~ 25 °C.
5.1.3 Relative humidity. ≤ 80 %.
5.1.4 Atmospheric pressure. the atmospheric pressure condition claimed by the
6.3.2 Use high value samples
TAKE anticoagulation whole blood, CENTRIFUGE to remove the plasma, making it
into concentrated blood cells; gradiently dilute the concentrated blood cells with their
own platelet plasma/dilution, dilute to at least 5 concentrations, so that the high
concentration value is close to the upper limit of the linear range and the low
concentration value is close to the lower limit of the linear range. MEASURE the blood
samples of each concentration gradient on the instrument, each sample is measured
3 times, TAKE the mean value. TAKE the dilution concentration as the independent
variable, the measured mean value of each dilution concentration as the dependent
variable, to calculate the regression equation. CALCULATE the corresponding
theoretical value of each dilution concentration point by the regression equation;
CALCULATE the absolute or relative percent error between the measured mean value
and the theoretical value.
6.4 Instrument comparability
USE a well-condition hematology analyzer to measure a fresh blood sample or a
calibrator with traceability; MEASURE 5 times consecutively and calculate the mean
value of each parameter. The mean values are used as the target values; CALIBRATE
the hematology analyzer with the above-mentioned sample or calibrator. At the end of
the calibration, use another fresh blood sample to be measured five times by two
difference hematology analyzers; CALCULATE the percent deviation between the
mean values of each parameter of the two hematology analyzers.
6.5 Test of accuracy of white blood cell classification for five-classifying
See Annex A (normative) for the test method.
6.6 Repeatability
TAKE 1 sample within the range specified in Table 2; REPEAT the measurement 10
times according to the conventional method; CALCULATE the coefficient of variation
(CV, %) according to Formula (1).
ܥܸ ൌ ݏ/̅ݔൈ100 % ... (1)
s - the standard deviation of the measured values of the sample;
̅ݔ - the average of the measured values of the sample.
6.7 Carry-over
TAKE the high-value blood samples within the range of Table 4; MEASURE three times
and shall provide at least the following information.
a) product name and model;
b) production company’s name, registered address, production address and contact;
