UA rapid diagnostic testing alone had sensitivity of 97.4%, specificity of 85.5%, PPV of 49.4%, and NPV of 99.6% in our patient cohort. Urine Gram stain rapid diagnostic testing alone had sensitivity of 97.3%, specificity of 73.8%, PPV of 33.6%, and NPV of 99.5%. Performing both UA and urine Gram stain resulted in sensitivity of 97.5%, specificity of 85.8%, PPV of 50.6%, and NPV of 99.6%. Urine culture was used as the gold standard for comparison.
