Definition
Noun: The presence of an abnormal amount of protein, primarily albumin but also globulin, in the urine. This condition is typically a symptom or indicator of kidney dysfunction or disease.
Usage
The term is used in medical contexts to describe a clinical finding, often detected through a urine test. It is a sign, not a disease itself, pointing to an underlying issue with the kidneys' filtering units.
Examples

- Persistent proteinuria is a key diagnostic marker for chronic kidney disease.
- The doctor explained that the proteinuria might be due to high blood pressure affecting the kidneys.
Advanced Usage
- Orthostatic proteinuria: A benign condition where protein is present in urine only when a person is upright (standing) but not when lying down.
- Massive proteinuria: A severe form where very large amounts of protein are lost in the urine, often associated with nephrotic syndrome.
Variants and Related Words
- Albuminuria: A more specific term often used interchangeably with proteinuria, referring specifically to the presence of albumin in the urine.
- Proteinuric (adj): Relating to or characterized by proteinuria.
- The patient had a proteinuric condition.
Synonyms

Related Phrases
- Trace proteinuria: A very small, often insignificant, amount of protein in the urine.
