Product Overview The NANKAI Nitrofuran Metabolites 4-in-1 Rapid Test Kit is a powerful, all-in-one lateral flow assay designed for the simultaneous detection of four critical nitrofuran metabolites (AOZ, AMOZ, AHD, and SEM) in fish, shrimp, crab, and other aquatic products.
In today’s strict international regulatory environment, a single nitrofuran residue violation can lead to shipment rejection, heavy financial losses, and damaged buyer relationships. Our 4-in-1 rapid test kit helps you screen all four metabolites quickly and accurately, significantly reducing risk and saving time.
