[Diagnostical values of antibody on A60 antigen in diagnostic of tuberculosis].
Aim of this research was to investigate diagnostic value of discovering of antibody on A60 antigen in patients who were tested for presents of Mycobacterium tuberculosis in there biological samples. We tested a samples of sputum, gastric juice, urine, cerebrospinal fluid and punctate from group of 353 patients who were suspected for tuberculosis. In all patients we were looking for antibodies classes A60 antigen. We used immune chromatographic "Hexagon TB" test, Germane company "Human Geselschaft fur Biochemica und Diagnostica". From 353 patients we found 58 (16.43%) patients with positive BK, 79/22,38%) patients with positive Lowenstein culture and 122 (34,55%) patients with antibody in sera on A60 antigen. Patients who were BK and Lowenstein positive, have had antibody in 94,23% cases, Patients who were BK negative and Lowenstein positive have had antibodies in 70,37% cases and patients who were BK negative and Lowenstein negative have had antibody in 19,03% cases. Patients with BK positive and Lowenstein negative results have had antibody in 50,00% cases. Difference between results is significant (p<0,01). From 122 patients with positive antibodies, 52 were BK positive and 68 have had positive Lowenstein cultures. From 231 patients with no antibody, just 6 were BK positive and 11 Lowenstein positive. In 62 patients with positive antibodies, were BK and Lowenstein negative. We confirmed that antibody on A60 antigen in microbiological positive patients are more often then in microbiological negative patients (p<0,001).
