Interpreting Urinalysis
Structures complete urinalysis interpretation with microscopy correlation and clinical significance.
Why This Skill Exists
Urinalysis is one of the most frequently ordered laboratory tests, providing critical information for diagnosing urinary tract infections, renal disease, diabetes, liver disease, and systemic conditions. Despite its ubiquity, urinalysis interpretation is frequently oversimplified, leading to missed diagnoses (nephrotic-range proteinuria attributed to "benign" proteinuria, dysmorphic RBCs indicating glomerular disease missed on microscopy, casts overlooked in a spun sediment). The CLSI GP16-A3 guideline and the European Confederation of Laboratory Medicine consensus provide standardized urinalysis methodology.
CAP accreditation (Urinalysis checklist, URN series) requires documented procedures for dipstick and microscopy, quality control of reagent strips, and competency assessment for personnel performing microscopic examination. CLIA classifies provider-performed microscopy (PPM) as a distinct complexity category with specific requirements. Automated urine analyzers are increasingly replacing manual microscopy, but correlation and reflex manual review remain essential for abnormal findings.
