systems and immunoassay methods to quantitatively or qualitatively detect various
analytes in human serum, plasma, or other body fluids, including luminescence
immunoassay analyzers based on chemiluminescence, electrochemiluminescence,
fluorescence, and other principles.
This standard does not apply to luminescence immunoassay analyzers based on image

GB 4793.9, and YY 0648.
4.10 Electromagnetic compatibility requirements
It shall comply with the applicable provisions of GB/T 18268.1 and GB/T 18268.26.
5 Test methods
5.1 Normal working environment conditions
5.1.1 Power supply voltage: 220 V±22 V; 50 Hz±1 Hz;
5.1.2 Ambient temperature: 10 ℃~30 ℃;
5.1.3 Relative humidity: 30%~70%;
5.1.4 Atmospheric pressure: 85.0 kPa~106.0 kPa;
5.1.5 Stay away from strong electromagnetic interference;
5.1.6 Avoid direct exposure to strong light;
5.1.7 There is a good grounding environment.
NOTE: When the conditions in 5.1.2~5.1.4 are inconsistent with the manufacturer's specifications, the
manufacturer's specifications shall prevail. The manufacturer shall specify them in the product technical
requirements.
5.2 Accuracy and repeatability of sample addition
There are two types of determination methods: colorimetry and weighing method.
Manufacturers can choose either method.
5.2.1 Weighing method
The weighing method is carried out according to the following steps:
a) Place the analyzer, degassed pure water, etc. in a constant temperature and
humidity laboratory for several hours before starting the test. Prepare a suitable
container (to prevent the water in the container from evaporating) and adjust
the zero value on an electronic balance with a graduation value of 0.01 mg;
b) Place the container in a suitable position, control the reagent needle or sample
needle to add a specified amount of degassed pure water into the container,
and then weigh its mass on the electronic balance;
c) Repeat the measurement 20 times for each specified addition amount. The
actual addition amount each time is equal to the mass of the degassed pure
water added divided by the density of pure water at the current temperature.
The density of pure water at different temperatures can be found in Appendix
A. Calculate the actual value vi of each addition and calculate the average value
̅;
The test can be carried out by the luminescent agent method or the reference light source
method. Use the analyzer and the reference light source or luminescent agent at two
levels, high and low, within the linear range to test. Test 10 times in a row and record
the luminescence values. Calculate the standard deviation and coefficient of variation
of the luminescence values. The coefficient of variation shall comply with the
provisions of 4.3.3.
5.4.4 Stability of luminescence value
The test can be carried out by the luminescent agent method or the reference light source
method. After the analyzer is turned on and in a stable working state, use the reference
light source or luminescent agent at two levels, high and low, within the linear range to
test; repeat the test three times, record the luminescence values, and calculate the
average value I0 of the measurement results. After 4 hours and 8 hours, repeat the test
three times on the machine respectively, and calculate the average values I1 and I2 of
the measurement results; take I0 as the reference value, and calculate the relative bias
(α) according to formula (6), which shall meet the requirements of 4.3.4.
where:
α -- the relative bias of luminescence values;
Ii -- the measured values at 4 h and 8 h;
I0 -- initial measurement value.
5.5 Carryover
The test is carried out as follows:
a) The manufacturer specifies the clinical test item;
b) Prepare a high-concentration sample (Iprimary) for the clinical test item; the
concentration of the high-concentration sample shall be at least 105 times the
detection limit of the detection system;
NOTE: If the detection system cannot accurately detect high-concentration samples due to
limitations in the measurement range of the analyzer or reagents, the dilution extrapolation
method can be used.
c) Use the reagents for the clinical test item specified by the manufacturer, take
high-concentration samples and zero-concentration samples as samples, and
test them on the analyzer in the order of high-concentration sample, high-
concentration sample, high-concentration sample, zero-concentration sample,
zero-concentration sample, and zero-concentration sample as a group; carry
out a total of 5 groups of such tests;
d) In each group of tests, the test value of the 4th sample is I4, and the test value
of the 6th sample is I6;
e) Calculate the carryover K of each group according to formula (7);
f) The carryover of the five groups shall all comply with the provisions of 4.4.
For analyzers that can only perform qualitative testing, it is not necessary to
calculate K, and I4, I5, and I6 are required to comply with the provisions of 4.4.
5.6 Intra-batch precision of clinical items
Using calibrators and kits for the clinical test item specified by the manufacturer, test
the intra-batch precision in accordance with the corresponding national standards,
industry standards, or test kit technical requirements, which shall comply with the
provisions of 4.5.
5.7 Main functions of the analyzer
The verification is performed according to the instructions; the functions shall meet the
requirements of 4.6.
5.8 Appearance
Visual inspection is carried out; the appearance shall comply with the requirements of
4.7.
5.9 Environmental test requirements
The test is carried out according to the method specified in GB/T 14710. The results
shall meet the requirements of 4.8.
5.10 Security requirements
The test is carried out according to the methods specified in GB 4793.1, GB 4793.6,
GB 4793.9, and YY 0648, and the results shall meet the requirements of 4.9.
5.11 Electromagnetic compatibility
