Hospital-Abu Anga-Tuberculosis ward. From 27th of August to 25th of September 2007. A total of 67 sputum samples
collected from the suspected people. The samples examined by FOB test and Z.N techniques. Ten out of the enrolled
samples, which showed positive FOB and negative Z.N techniques selected confirmed by using PCR techniques. The
result showed that there were 12 (17.9%) of cases were Z.N (+ve), while 55 (82.1%) of cases were Z.N (-ve). It was also
showed that there were 53(79.1%) of cases were FOB test (+ve), while 14(20.9%) of cases were FOB test (-ve).
According to PCR techniques, after performed 10 samples that showed Z.N (-ve) and FOB test (+ve), it was noted that
there were 4(40%) of cases were PCR (+ve), while 6(60%) of cases were PCR (-ve).
