    Study Notes

    Urinalysis

    • Urinalysis is a diagnostic test that analyzes the characteristics and constituents of urine to detect various health conditions.

    Urine Composition

    • Normally, urine comprises 96% water and 4% dissolved ions, metabolic wastes, and other metabolites.
    • Urochrome, a byproduct of heme degradation, gives urine its pale yellow color.
    • Urine typically has an average pH of 6, ranging from 4.5 to 8.

    Urine Volume

    • Normal urine volume is 800 to 2,000 mL per day over 24 hours.
    • Single urination volume typically ranges from 210 mL to 500 mL.
    • Measuring urine output helps identify disorders like dehydration, inadequate fluid intake, or chronic kidney disease.

    Urine Color

    • Urine color can indicate dehydration or excess water intake.
    • Pink urine may indicate the presence of blood or consumption of certain foods like beets.
    • Urine color can be influenced by diet and medications.

    Urine Odor

    • Hydrated urine has little to no odor, while concentrated urine can have a strong ammonia smell.
    • Certain foods and medications can alter the smell of urine.
    • Unusual odors may indicate medical disorders, such as diabetic ketoacidosis.

    Urine Precipitate

    • Normally, urine is clear of precipitate.
    • Cloudy urine may indicate cellular materials or proteins, which can suggest dehydration, high protein diet, urinary tract infection, or kidney damage.
    • Follow-up questions and additional analysis, like urinalysis, can guide diagnosis.
