Albuminuria
From Wikipedia, the free encyclopedia

| MeSH | D000419 |
Albuminuria is a pathological condition where albumin is present in the urine. It is a type of proteinuria.
[edit] Measurement
The amount of protein being lost in the urine can be quantified by collecting the urine for 24 hours, measuring a sample of the pooled urine, and extrapolating to the volume collected.
[edit] Causes
The kidneys normally filter out large molecules from the urine, so albuminuria can be an indicator of damage to the kidneys. It can also occur in patients with long-standing diabetes especially type 1 diabetes.
Causes of albuminuria can be discriminated between by the amount of protein excreted.
- The nephrotic syndrome usually results in the excretion of about 3.0 to 3.5 grams per 24 hours.
- Nephritic syndrome results in far less albuminuria.
- Microalbuminuria (less than 300mg) can be a forerunner of diabetic nephropathy.
