Urine microalbumin(mALB) Determination Reagent(Immunoturbidimetry) is an in vitro diagnostic quantitative test kit. In clinical practice, trace protein indicators are usually used to monitor the occurrence of nephropathy. The detection of trace protein is the most sensitive and reliable diagnostic indicator for early detection of kidney disease. The barrier function of the glomerular basement membrane is damaged, the albumin filtered through the basement membrane increases significantly, and mALB will also increase significantly.
