The Use of Phase Contrast Microscopy to Identify Bacteriuria and Hence Predict Cultures Indicative of Urinary Tract Infections

A study that supports the use of phase contrast microscopy as a reliable test with high sensitivity, specificity, positive and negative predictive values in the rapid diagnosis of urinary tract infections.


Objective: To determine whether phase contrast microscopy of uncentrifuged urine specimens could rapidly and accurately identify bacteriuria and predict microbiology culture results.

Methods: A prospective study was performed at the Clinical Microbiology Laboratory of the EWMSC, Trinidad. Urine samples were examined via phase contrast microscopy at the time of culture.
