Journal Title: International Journal of Pharmaceutical and Medicinal Reserach - Year 2014, Vol 2, Issue 5
Abstract
Background: Tuberculosis is a major cause of illness and death worldwide, especially in Asia and Africa. The objective of this study was to compare the results of bacteriological examination of tuberculosis suspects taken under direct observation during collection with specimens taken without observation.

The study population was Pulmonary TB suspects attending Gedarif Teaching Hospital, Gedarif, Sudan. The sample size was calculated as 164 for the cases and 164 for the controls. The patients in the study group were observed by the laboratory technician while coughing to provide the sputum samples for testing AFB for pulmonary tuberculosis diagnosis. The sputum samples for the control group were taken without observation. A tested questionnaire was used to collect demographic data and the laboratory register was used to obtain sputum. Analysis was done by SPSS version 16. Informed consent was obtained from all participants. Results: 46.3% of the samples were positive when the sputum was collected under direct observation by the laboratory technician while 29.9% of the samples were positive when taken without observation.
