Because microalbuminuria may be reversible if diabetes is well controlled, its early detection may be very beneficial. However, microalbuminuria is not generally measurable by the simple test ordinarily used to detect proteinuria because it lacks sensitivity. For the detection of microalbuminuria, RIA, ELISA and nephelometry assay are used. However they have complicated procedures and are time consuming.
Wako’s Microalbumin is a turbidimetric immunoassay using polyclonal antibodies against human albumin and allows accurate and reproducible measurement of microalbuminuria with a simple procedure.

Performance characteristics
PrincipleWhen a sample is mixed with the antibody solution in the buffer, albumin in the sample combines specifically with the anti-human albumin antibody to yield immune complexes resulting in increased turbidity. Since the degree of turbidity is proportional to the amount of albumin in the sample, the amount of albumin can be determined by measuring the turbidity.
