摘要: Inadequate case detection has been identified as one of the reasons for high burden tuberculosis (TB) in world especially poor resourced countries Africa and Asia. This retrospective laboratory study involving review specimens processed at TB Department Medical Microbiology Parasitology, University College Hospital, Ibadan, Nigeria was carried out over a period five years (January 2006-December 2010) to access epidemiology smear-negative TB. Of 3468 processed, 2,175 (62.7%) were from males while lower percentage (37.3%)1293 females, giving M:F = 1:0.37. Over half specimens, 2,046 (59.0%) patients aged 21 60 years, 392 (11.3%) 11 20 825 (23.8%) above 205 (5.9%) age 1-10 years. Most 2,663 (76.8%) sputum 201 (5.8%) gastric washings. Three hundred nine (8.9%) smear positive culture positive. However, 83 (2.6%) 3159 (false negative) 66 (21.4%) 309 smear-positive negative positive). The majority, 3010 (86.8%) both tests. false 51 samples representing (61.4%), 19 (22.9%) washings 13 (15.7%) extra-pulmonary sites (CSF, aspirates, ascitic fluids, etc). findings 2.6% but this reveals that addition microscopy suspected cases is necessary diagnostic /confirmatory tool tuberculosis.
