Method Gentamicin ELISA kit was used to establish a method for the determination of gentamicin residues. The linearity of the standard curve of the method and the accuracy, precision, specificity, durability, detection and quantitative limits of the linear range were verified. Results The standard curve of the test was linear, with correlation coefficient >0.98. The recovery rates of the high, medium and low concentrations of gentamicin were 92.7％-123.6％. The relative standard deviation of same batch samples tested was 8％. The relative standard deviations of same batch samples tested by different test personnel and different batches of test kits were all <15％. The recovery rates of gentamicin were 95.9％-121.3％. The method had good durability in the temperature range of (37±1)℃. The detection limit of gentamicin was 0. 040 ng/ml and the quantitative limit was 0.135 ng/ml. Conclusion The method is effective for the detection of gentamycin in live attenuated oral poliovirus vaccine (human diploid cell).
