Intended Use

For the quantitative in vitro determination of Microalbumin in urine.

Clinical Significance

Albumin is one of the major plasma proteins. In normal circumstances, albumin molecules are too large to cross the glomerular basement membrane. Therefore, albumin is usually present in very low concentration in urine. Damage to the glomerular basement membrane can alter its permeability. Albumin is then able to enter the urine. Sustained elevations of urinary albumin concentrations are called Microalbuminuria.


Undiluted sample is added to a buffer containing antibody specific for human serum albumin. The absorbance (340 nm) of the resulting turbid solution is proportional to the concentration of albumin in the sample urine. By constructing a standard curve from the absorbances of standards, the albumin concentration of sample can be determined. The assay can be carried out manually (at room temperature) or using an automated analyser.
