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.
