Objective To explore application effect of colloidal gold method to retest routine positive specimens of infectious diseases.Methods The paper chose routine positive specimens of infectious diseases detected by chemiluminescence method from January 1,2018 to December 31,2022 in Nanjing City Liuhe District People's Hospital,and retested routine positive specimens of infectious diseases with colloidal gold method.Results Positive samples of syphilis antibody,hepatitis C antibody and hepatitis B surface antigen increased year by year.Positive samples of syphilis antibody,hepatitis C antibody and hepatitis B surface antigen increased by 109%,103%and 65%respectively compared with 2018,retest cost increased by 111%,97%and 63%respectively.Total cost of 72985.9 yuan was saved for the department with colloidal gold method for three items from 2018 to 2022,and saved reagents could increase benefits for the department by 205568.9 yuan.Conclusion Colloidal gold method can achieve ideal application effect for retesting routine positive specimens of infectious diseases,can save costs,and improve detection effect.
