High Standards and Rigorous Requirements: Addressing On-Site Supervision Challenges

This verification initiative directly addressed core needs in on-site supervision of veterinary drug residues in aquatic products, aiming to identify efficient and reliable rapid-testing technologies. The evaluation criteria were comprehensive, focusing on:

Control of false positive and false negative rates: Ensuring accurate and reliable results to avoid misjudgment.

Compliance rate for actual samples: Required to reach 100%, ensuring detection capability for real-world samples.

Testing time: Small-batch samples must be processed within 120 minutes, and large-batch samples within 10 hours, meeting the efficiency demands of on-site screening.

The verification process was rigorous and standardized, supervised throughout by an expert panel. Technicians from Kwinbon Tech conducted on-site tests using their self-developed rapid-testing products on samples including blank controls, spiked positive samples, and actual positive samples. The expert panel independently observed results, recorded data, and performed strict statistical analysis to ensure impartiality.

Outstanding Performance of Kwinbon Tech’s 15 Products

The circular confirmed that all 15 of Kwinbon Tech’s rapid-testing products—covering residues such as nitrofuran metabolites, malachite green, and chloramphenicol, and utilizing multiple technological platforms including colloidal gold test strips—passed all verification items at once, fully meeting or exceeding the established evaluation criteria. The products demonstrated excellence in core metrics like false positive rate, detection rate for spiked positive samples, actual sample compliance rate, and testing time, proving their stability and efficiency in complex field environments. Detailed verification data are attached to the circular (records from both the expert panel and enterprise technicians).
