Abstract: Objective To study the relationship between anti-mycobacterium tuberculosis antibody in differential stage of pulmonary tuberculosis and the practical value of curative effect of pulmonary tuberculosis.Methods Level of serum anti-mycobacterium tuberculosis antibody were measured in the progressive stage,absorptive resolving stage and stable stage.Results The absorptive,resolving and stable stage of anti-mycobacterium tuberculosis which antibody positive rate was 27.5% and 19.5% respectively,compare with significance difference(P<0.01 ).The negative rate converted of antibody tuberculosis was 75.5%.Conclusion There is high practical value of serum anti-mycobacterium tuberculosis antibody level in the curative effect of pulmonary tuberculosis.
