ABSTRACT
Background: The primary aim of this study was to evaluate laboratory diagnosis of urinary tract infection using diagnostics tests in adult patients. Methods: Among the diagnostic tests, urinalysis is useful mainly for excluding bacteriuria. For isolation of pathogenic bacteria semiquantitative culture techniques was used and biochemical tests were done to differentiate Gram +ve and Gram –ve bacteria. Results: The incidence of pathogenic infection caused by Escherichia coli accounts for 216 cases (60%) followed by Pseudomonas, Staphylococcus aureus and Klebsiella. Conclusion: Physicians should distinguish urinary tract infections caused by different organisms for an effective treatment and appropriate clinical information gives clues for better diagnostic evaluation and their susceptibility to antimicrobial agents as well addressing host factors that contribute to the occurrence of infection.
