Increased urinary albumin loss is considered a clinically important indicator of deteriorating renal function in diabetic subjects and regular screening of urinary albumin loss is valuable in monitoring type 1 and type 2 diabetes. Prospective studies have demonstrated that increased urinary albumin excretion precedes and is highly predictive of diabetic nephropathy, end stage renal disease, cardiovascular mortality, and total mortality in patients with diabetes mellitus. In addition, increased urinary albumin excretion identifies a group of non-diabetic subjects at increased risk for coronary artery disease.
Urine Albumin reagent is used to measure albumin concentration by a turbidimetric method. In the reaction, anti-human serum albumin antibodies combine with albumin from the sample to form immune complexes that scatter light in proportion to their size, shape and concentration. The absorbance of these aggregates is proportional to the albumin concentration in the sample. Change in absorbance is measured at 380nm with subtraction of a reference wavelength at 800nm.

The assay is validated and linear from 1.5 to 30 mg/dL. Samples exceeding the upper limit of linearity are diluted and repeated.
