Abstract：Objective To explore the clinical value of digestion and collection method in detection of mycobacterium tu-berculosis in sputa samples. Methods A total of 225 sputa samples of patients suspected as having tuberculosis from March to October 2012 were collected, and mycobacterium tuberculosis was detected with digestion and collecting method and direct smear method respectively, and then the results of the two methods were compared. Results The positive rates of 225 sputa samples were 38. 67% by digestion and collection method and 25. 78% by direct smear method respectively, and the positive rate by di-gestion and collection method was significant higher than that by direct smear method (P<0. 05). The positive rates of myco-bacterium tuberculosis in different quantities detected under microscope were significantly higher than those by digestion and col-lection method, especially when the quantity of mycobacterium tuberculosis was at (++++) , and at the moment the positive rate of digestion and collection method was 35. 63%, while the positive rate of that direct smear method was 12. 07%, and the differences between the groups were statistically significant (P<0. 05). Conclusion Digestion and collection method in de-tection of mycobacterium tuberculosis in sputa samples is safe and simple with a higher positive detection rate.
