Urinalysis and Other Body Fluids

  1. Specimen Handling and AcceptabilityCollection, labeling, storage, and preservation determine whether a urine specimen is suitable for testing.
  2. Urine Specimen TypesRoutine, timed, and midstream urine collections serve distinct purposes and have different sources of error.
  3. Specialized and Forensic CollectionsProstatitis localization and federal workplace drug testing require distinct collection and interpretation procedures.
  4. Color, Clarity, and OdorUrine color, clarity, and odor require interpretation with chemical and microscopic findings.
  5. Specific Gravity and OsmolalitySpecific gravity and osmolality assess different properties of urine concentration, which explains why their results may disagree.
