Albuminuria occurs when kidneys start leaking albumin into the urine due to high permeability of the kidneys for the albumin.
Microalbuminuria is defined as excretion of between 30 mg and 300 mg of albumin a day [24 hoursin the urine.
- Less than 30 mg is insignificant.
- Over 300 mg is albuminuria or macroalbuminuria.
Patients should be tested for proteinuria if they have any of the following risk factors:
- Glomerular Filtration Rate ≤60 ml/min/1.73 m2.
- Cardiovascular disease.
- Renal tract disease
- Renal Stones
- Prostatic hypertrophy.
- Family history of chronic kidney disease (CKD)
