(Chemiluminescent immunoassay)
1 Scope
This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules, identification, labels, instructions, packaging, transportation and storage of alpha-fetoprotein quantitative detection reagent (kit) (chemiluminescence immunoassay).
This standard is applicable to the quantitative detection of the alpha-fetoprotein quantitative detection reagent (kit) (hereinafter referred as “AFP reagent (kit)”) in the human blood matrix or other body fluid components, based on the principle of chemiluminescence immunoassay. It includes the enzymatic and non-enzymatic chemiluminescence immunoassay detection reagent (kit) in carriers of micro-plates, tubes, magnetic particles, micro-beads and plastic beads.
This standard is not applicable to the requirements of calibrators and quality control products in the kit.
2 Normative references
The articles contained in the following documents have become part of this standard when they are quoted herein. For the dated documents so quoted, all the modifications (excluding corrections) or revisions made thereafter shall not be applicable to this standard. For the undated documents so quoted, the latest editions shall be applicable to this standard.
GB/T 21415-2008 In vitro diagnostic medical devices - Measurement of quantities in biological samples - Metrological traceability of values assigned to calibrators and control materials (ISO 17511. 2003, IDT)
3 Terms and definitions
For the purpose of standard, the following terms and definitions shall apply. 3.1
Chemiluminescence, CL
Because that the chemical reaction can generate the substances of electronic energy level to be in the excited state, the latter can generate photon by transition release energy, thereby to cause the luminescence phenomenon.
3.2
Chemiluminescent immunoassay, CLIA
The luminescence phenomenon that is caused by – because of chemical reactions, the substances with generated electron energy-level at excited state unleash energy and produce the photons through transition.
3.3
Minimum detectable concentration / detection limit, limit of detection
It refers to the measured minimum value that can be declared as varying from zero at a certain probability in the sample. [ISO/DIS 18113-1]
Note 1. Sometimes it is incorrectly referred to as a sensitivity of analysis. Note 2. The minimum detection limit in this standard is the minimum concentration which differs from zero and is at the confidence interval of not less than 95%.
3.4
Analytical specificity
The capability of measurement procedure that only measures the sample
to-be-measured.
[GB/T 19702-2005/ISO 15193.2002, 3.8]
Note 1. Lack of specificity may be referred to the analytical interference. Note 2. The lack of specificity may be referred as due to cross reaction in the immunochemical measurement procedure.
Note 3. The specificity of the measurement procedure shall not be confused with the diagnostic specificity.
3.5
Linearity of a measuring system
The directly proportional capacity between the given measuring result and the measured value in the sample. [ISO/DIS 18113-1]
Note 1. For in vitro diagnostic (IVD) medical devices, the linearity-related results of measurement are the measurement values after correction or linearization.
minimum detection limit. The result shall comply with the requirements in 5.4. 6.5 Linearity
The high-value samples of which the value is near to the upper limit of linear range are diluted into at least 5 concentrations according to certain proportions. In which, the samples with low value concentration shall be near to the lower limit of the linear range. Operate according to the instructions of reagent (kit). Respectively repeat the detection for 2 times to each concentration of the samples. Calculate the mean value. For the mean value and dilution ratio, use the least squares method to perform straight line fitting. Calculate the linear correlation coefficient r. The result shall meet the requirements in 5.5. 6.6 Repeatability
Samples with at least two concentrations 10 IU/mL ± 2 IU/mL and 100 IU/mL ± 20 IU/mL shall be repeatedly detected for 10 times. Work out the mean value M and standard deviation SD of the 10-times measurement results. Coefficient of variation CV is obtained and based on Formula CV=SD/M×100%. The results shall be in accordance with the requirements of 5.6.
6.7 Within-batch difference
Use three batch of reagent kits to respectively detect the same sample with concentration of 100 IU/mL ± 20 IU/mL. Repeat for 10 times respectively. Calculate the mean M and standard deviation SD of 10-times measurement results. Coefficient of variation CV is calculated according to Formula CV=SD/M×100%. The results shall comply with the requirements of 5.7.
6.8 Stability
a) Stability within the validity. Take the sample that has been expired to perform the detection according to the methods of 6.3, 6.4, 6.5 and 6.6. It shall comply with the requirements of 5.8 a).
b) Thermal stability test. Take the sample within the period of validity to place for 3 days at 37°C. Perform the detection according to the methods of 6.3, 6.4, 6.5 and 6.6. It shall comply with the requirements of 5.8 b).
