| dc.description.abstract | Lung tuberculosis is one of transmitted diseases which are caused
by Mycobacterium tuberculosis through nuclei droplet. Diagnosis for lung
tuberculosis is usually detected by the examination of direct sputum removal,
thorax photo, and Culture.
The type of the research was descriptive study by using diagnostic test and
the samples consisted of sputum and thorax photo. The sputum was taken
accidentally, in the morning, and accidentally which was examined by using Ziehl
Nelsen method and culture.
Objective of the research: The objective of the research was to find out the
effectiveness of examining direct BTA removal and radiology which were
compared with Culture..
Materials and Method: The samples were taken from Private Practice of
Tuberculosis Specialists in Medan and in BP4, Medan which had fulfilled
inclusive criteria, radiology examination and three times of phlegm taking for
direct BTA removal and culture were performed; after that, radiology diagnostic
test for direct BTA removal was compared with Culture.
Result of the research: 60 samples on direct removal method indicated the value
of sensitivity of 59.38%, specificity of 92. 86%, value of positive prediction of
90. 48%, value of negative prediction of 66. 7%, ratio of positive likelihood of 8.31,
and ratio of negative likelihood of 0. 44.
Radiology method indicated sensitivity of 62.63%, specificity of 82.14%, the
value of positive prediction of 80. 77%, value of negative prediction of 67.65%,
ratio of positive likelihood of 3. 67, and ratio of negative likelihood of 0. 4 2. Of the
21 samples, positive BTA which underwent minimum lung damage of 4 (6. 7%),
moderate damage of9 (15.0%), and wide damage of5 (8.3%).
Conclusion: The result of the research showed that radiology examination
indicated that the value of sensitivity was higher than direct removal method,
compared with culture as gold standard in BTA examination.
That clinical benefit was bigger in direct removal method can be seen from
the value of positive prediction which was higher than radiology method so that it
is recommended that both examination techniques be used to diagnose lung
tuberculosis. | en_US |
