ABSTRACT
Objective To explore the application value of interferon gamma release assay (IGRAs)in the clinical detection of tuberculosis infected T lymphocytes.Methods Used IGRAs method to detect the 11 968 outpatients and hospitalized pa-tients from 2013 to 2016 with tuberculosis screening.According to the distribution department analysis,also of positive case detection according to age and gender were analysis and comparison and analysis on the uncertainty of results,different methods were compared.Results Among the 11 968 cases,2 048 cases were positive,the positive rate was 17.11%,and the uncertain result was 107 cases,which accounted for 0.89% of the total number.The positive rates from 2013 to 2016 were 19.65%,21.35%,15.82% and 13.56%,respectively.In the detection and screening of pulmonary and pulmonary tuberculo-sis,the positive rates of the department of respiration,the digestive department,the oncology department,the department of neurology and the department of gynecology were 22.07%,20.27%,23.38%,12.84% and 11.86%,respectively.In the positive screening,men accounted for 62.11%,women accounted for 37.89%,men were significantly higher than women.By age group,was less than or equal to 15,16~25,26~45,46~65,was more than orequal to 66 years old,positive rate were 1.96%,18.51%,16.54%,21.25% and 25.73%,respectively.Analysis of uncertain outcome data,department of respira-tion,rheumatism,department of hematology,accounted for 1.99% and 2.35%,respectively.Compared with other laboratory methods,the IGRAs method had obvious advantages.Conclusion Tuberculosis occurs in various body organs,there were differences in gender and age of Mycobacterium tuberculosis infection.IGRAs is a sensitive and specific method for rapid de-tection of Mycobacterium tuberculosis infection,although it can not be used as a diagnostic indicator,but in patients with suspected tuberculosis IGRAs has a larger clinical application value for the further diagnosis of disease.
