    【Abstract】Objective prevent tetanus antitoxin (TAT) false positive skin test results of the method. Methods dilution skin test, skin test solution strictly controlled method of preparation and intradermal injection method provides the best observation time for the skin test results, standardized skin test results to determine the standards, the principle of strict control of TAT injection. TAT to adopt a new method. Results skin test, skin test positive rate of 7.2%, and the desensitization injection method used to make TAT injection rate of 99.8%. Conclusion TAT skin test solution to master the best method of preparation, the best observation time and the injection of the principle of TAT can significantly reduce the rate of false positive skin test results, increased opportunities for patient treatment. ......
