Microalbumin ELISA kit

Storage Instruction:Store the kit at 4°C.
Description:
Under normal physiological conditions very little albumin is present in the urine. Approximately 99% of the filtered albumin is reabsorbed in the proximal tubule. In pathologic conditions when glomerular capillary wall permeability and/or filtration rate increase, albumin excretion along with other macromolecules in urine also increases. On the other hand, when proximal tubular reabsorptive capacity decreases, excretion of smaller macromolecules such as beta 2 micro globulin and lysozyme in urine increases. Thus, determining the clearance ratio of urinary albumin to beta 2 micro globulin can help localize the site of renal impairment.
