Investigation and Analysis on the Performance of Colloidal Gold Kit of Fipronil and Isocarbophos
The application effects of colloidal gold kits of fipronil and isocarbophos from three manufacturers in different matrices are studied,and the accuracy,sensitivity,specificity,false negative rate and false positive rate of their products are investigated.The results show that the sensitivity and accuracy of colloidal gold kits of fipronil and isocarbophos from the three manufacturers are high,which meet the requirements of the instructions.The results of cross reaction are negative,indicating good specificity.The results of blank matrix labeling are consistent with those of blank matrix labeling,indicating that the false negative rate and false positive rate are 0.This shows that the detection results of colloidal gold kits of fipronil and isocarbophos from the three manufacturers are accurate and reliable,and can be widely used.
