Operation Standards for Rapid Detection Laboratories of Agricultural Products
1Key Takeaways
This standard provides detailed guidelines for the operation of rapid detection laboratories in the agricultural product sector. It outlines the necessary procedures, equipment requirements, and quality control measures to ensure consistent and reliable testing results. The document covers aspects such as sample handli…
2Expert Interpretation
An in-depth interpretation of Qinhuangdao's local standard DB1303/T 392-2025 "Operational Specifications for Rapid Testing Laboratories of Agricultural Products", covering core contents such as laboratory construction requirements, testing process control, and quality management system, and is applicable to the implementation of rapid testing in farmers' markets, supermarkets and regulatory agencies.
Standard Framework and Technology Evolution
As a detailed extension of GB/T 27404 at the regional level, this standard innovatively integrates the operating requirements of rapid testing equipment such as colloidal gold detector and enzyme-linked immunosorbent analyzer. Compared with the 2017 version of the national standard, new digital management clauses such as reagent batch number management (4.5.2) and electronic file trace retention (9.3.1) have been added.
Analysis of core requirements
| Dimensions | Requirements of this standard | General laboratory differences |
|---|---|---|
| Environmental control | Testing area needs to be physically isolated (4.1.2) | Open space is usually allowed |
| Personnel qualifications | Dual audit mechanism (6.2.3) | Common for single-person operation |
| Positive handling | 4-hour retest time limit (7.2) | Usually within 24 hours |
Key points for implementation
Typical application scenarios
When a wholesale market uses rapid pesticide residue detector to implement this standard, special attention should be paid to the following:
- A blank control should be performed after starting the machine every day (6.2.1)
- Reagent kits from different batches should be used alternately (6.2.4)
- The frequency of temperature and humidity recording should not be less than 2 times/day (4.1.1)
Advanced quality control
The accuracy verification required by Clause 8.2 of the standard should include:
- Comparison experiment between each batch of reagents and standard substances
- Consistency test of personnel operation (CV value ≤15%)
- Analysis of differences between equipment (≤10%)
