Application of time-resolved fluoroimmunoassay in detection of veterinary drug residues

In recent years, more and more cases of food poisoning caused by veterinary drug residues are reported. The detection of veterinary drug residues is significant. In traditional detections such as gas chromatography and liquid chromatography, the pretreatment is fussy and the instrument is expensive. The sensitivity of enzyme-linked immunosorbent assay is low. The time-resolved fluoroimmunoassay(TRFIA) is easy to operate with high sensitivity. The detection for veterinary drug residues by TRFIA has attracted much attention. The principle and advantages of TRFIA are described in the paper, the application of TRFIA in veterinary drug residues detection is also summarized. Compared with other traditional detections, TRFIA is likely to become a conventional method for veterinary drug residues detection.
