Application of tuberculosis infection of T cells spot test in the diagnosis for pulmonary tuberculosis in elderly pa-tients with chronic obstructive pulmonary disease

Objective To investigate the application value of tuberculosis infection of T cells spot test in the diagnosis for pulmonary tuberculosis in elderly patients with chronic obstructive pulmonary disease (COPD). Methods According to test different ways,64 elderly COPD patients with pulmonary tuberculosis were divided into the two groups.The control group(n=32)was checked by tuberculosis antibody test,and the study group(n=32)received T cells infected with tuberculosis spot test.The two sets of results were observed and compared. Results The study group by T cell spot test TB infection,29 cases were detected positive(90. 63%),3 cases of negative(9.37%);tuberculosis antibody detection by the control group,23 cases were detected positive(71.88%),9 negative patients(28.12%).Compared the two groups,the study group had higher positive rate(χ2=3.954 7,P<0.05),and negative rate was lower(χ2=3.914 7,P<0.05). Conclusion Tuberculosis infection T cell spot test in the diagnosis of pulmonary tuberculosis in patients with COPD in the elderly has greater value,more accurate diagnosis,reliability and worthy of promotion.
