Laboratory assay overview
The determination of proteinuria is a well established laboratory procedure for the evaluation of renal disease (glomerular, tubular and overflow proteinuria), urinary tract inflammation, orthostatic proteinuria and preeclampsia (a potential complication of pregnancy). A more rapid clinical assessment of proteinuria using a 12-hour specimen enables a faster diagnosis with subsequent intervention in several of the clinical conditions cited above.
