albuminuria
The presence in the urine of serum albumin. It indicates renal dysfunction and occurs in primary renal failure (glomerular) and congestive heart failure. There may be a sufficient loss to cause hypoalbuminemia.

albuminuria
(albyōō′minyōō′rēə)
n
n
(hyperproteinuria, proteinuria, pro-teuria), the presence of clinically detectable amounts of protein in the urine. Usually less than 100 mg/24 hr may be found normally by special methods. The usual protein is albumin, although globulins, Bence Jones protein, and fibrinogen may be present and may exceed the amount of albumin. The condition may be caused by prerenal or renal disease or by inflammation of the urinary tract.

Symptoms
Heavy whitish foam in urine.
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.
Causes
The kidneys normally do not filter large molecules into the urine, so albuminuria can be an indicator of damage to the kidneys or excessive salt intake. 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 (between 30 and 300 mg/24h,[1] mg/l of urine[2] or µg/mg of creatinine[3]) can be a forerunner of diabetic nephropathy.
Treatment
There is some evidence that dietary interventions (to lower red meat intake) can be helpful in lowering albuminuria levels.[4]
