Aka: Urinalysis, Urine examination, Urine Dipstick
  1. Method
    1. Multiple reagent test strip
    2. Urine Microscopic Exam
  2. Technique
    1. Collection
      1. First morning sample
      2. Midstream, clean catch collection
      3. Minimum volume of 3 ml (1 ml for children)
      4. Analyze within 1-2 hours or refrigerate
    2. Preparation of spun urine for microscopy
      1. Start with 10 ml of midstream urine
      2. Centrifuge for approximately 10 minutes (typically at near 2000 rpm)
        1. Discard supernatant
        2. Suspend sediment in 0.3 ml saline or supernatant
      3. Examine under microscopy at 400x magnification
        1. Review at least 10-20 microscopic fields
  3. Labs: General Tests
    1. Urine Appearance (Urine Color)
    2. Urine Odor
    3. Urine Specific Gravity
    4. Urine pH
  4. Labs: Kidney and Urinary Tract Disease Tests
    1. Urine Protein
    2. Urine Blood
      1. Gross Hematuria
      2. Microscopic Hematuria
  5. Labs: Urinary Tract Infection Tests
    1. Urine Leukocyte Esterase
    2. Urine Nitrite
  6. Labs: Metabolic Disease Tests
    1. Urine Glucose
    2. Urine Ketones
    3. Urine Bilirubin
    4. Urine Urobilinogen
  7. Labs: Urine Microscopic Exam (based on spun urine)
    1. Urine Red Blood Cells
      1. Microscopic Hematuria if 3 RBC/hpf or higher
    2. Urine White Blood Cells
    3. Urine squamous epithelial cells
      1. Suggests vaginal contaminant if >5 squamous epithelial cells/hpf

Urinalysis (C0042014)

Definition (NCI_NCI-GLOSS) A test that determines the content of the urine.
Definition (NCI) Laboratory analysis of urine, commonly used to aid in the diagnosis of disease or to detect the presence of a specific substance. It involves examination of the urine by physical or chemical means as well as microscopic examination that helps to screen for urinary tract infections, renal disease, and diseases of other organs, that result in abnormal metabolites (break-down products) appearing in the urine.
Definition (CSP) physical, chemical or microscopic analysis or examination of urine.
Definition (MSH) Examination of urine by chemical, physical, or microscopic means. Routine urinalysis usually includes performing chemical screening tests, determining specific gravity, observing any unusual color or odor, screening for bacteriuria, and examining the sediment microscopically.
