The presence of protein in the urine is an indicator of various kidney diseases, including the progressive decline of the glomerulus.
Kidney disease develops in 30-40% of insulin-dependent diabetics. The early detection of small quantities of albumin in the urine (concentrations of the order of 20 to 50 mg/L) enables early diagnosis of the disease, i.e. when the renal lesions are still at a reversible stage. The qualitative detection of albumin in urine is therefore of great clinical importance.
