This company has introduced an immunoturbidimetric assay for the measurement of microalbumin in urine.
Elevated levels of microalbumin indicate a high probability of damage to the glomerular filtration capacity of the kidney. Microalbumin is used to follow the progression of renal disease in Type I Diabetes and Stage III or incipient nephropathy. It is also useful in patients with hypertension as an indicator of organ damage associated with lower life expectancy. Another use of microalbumin is during pregnancy as a predictor of preeclampsia.
The immunoturbidimetric technology measures the increased turbidity (at 340nm) resulting from antibody-antigen complexes formed when samples and antibody reagent are mixed. The chemistry analyzer then constructs a standard curve and calculates the patient concentrations.
