Abstract


The gold standard for TB still has some drawbacks, such as a long duration for culture examination and the rolated facilities are not
always available in all laboratories. One of methods in diagnosing tuberculosis infection is by immunochromatography (ICT). MYCOTEC
TB xp (recombinant) is one of serologic tests using immunochromatography principle. MYCOTEC TB xp uses recombinant antigens 38
kDa, 16 kDa, 6 kDa and Early Secreted Antigen Target (ESAT-6). This method is expected so far diagnose TB in a short time and has a
high accuracy. Evaluating the immunochromatography method in detecting antibody by tuberculosis antigen in lung TB patients as will
those with nonTB lung disease (lung tumor, bronchial asthma, pneumonia, chronic obstructive lungdisease). Serum samples of 30 TB
patients in BP4/Karang Tembok Hospital Surabaya and 30 non TB patients in the Dr. Soetomo Hospital Surabaya. Detection of antibody
to tuberculosis antigen was done with MYCOTEC TB xp. In this study found is prond 30 TB patients using MYCOTEC TB xp was positive
in 23 samples and negative in 7 samples. From the 30 nonTB patients MYCOTEC TB xp was positive in 4 samples and negative in 26
samples. It can be uncloaded so far that the diagnostic sensitivity of MYCOTEC TB xp was 76.7% (23/30) and diagnostic specificity was
86.7% (26/30). MYCOTEC TB xp has an intermediate diagnostic sensitivity of 76.7% and a high diagnostic specificity of 86.7%.
