Automated Flow Cytometry: An Alternative to Urine Culture in a Routine Clinical Microbiology Laboratory?

Area of Science:

• Clinical Laboratory Science
• Medical Diagnostics
• Urology

Background:

• Urine culture is the gold standard for diagnosing urinary tract infections (UTIs).
• High rates of negative urine cultures create a significant workload in clinical laboratories.
• Existing screening methods lack adequate sensitivity and negative predictive value.

Purpose of the Study:

• To review and discuss the feasibility of urine flow cytometry (UFC) as a screening tool for UTIs.
• To evaluate UFC's utility as an alternative analytical technique in urinalysis.
• To identify methods for improving laboratory efficiency in UTI diagnostics.

Main Methods:

• Literature review of studies on urine flow cytometry.
• Analysis of data regarding UFC's performance in routine clinical laboratories.
• Discussion of UFC's sensitivity (SE) and negative predictive value (NPV).

Main Results:

• Flow cytometry has demonstrated efficacy in routine clinical laboratory settings.
• UFC presents potential as an efficient screening method for urine samples.
• The review discusses current literature on UFC's capabilities.

Conclusions:

• Urine flow cytometry (UFC) is a feasible alternative for urinalysis.
• UFC can potentially reduce the number of unnecessary urine cultures.
• Further evaluation of UFC is warranted for optimizing UTI diagnosis.
