Abstract
Today, there is no reference method for the measurement of urinary proteins. The difficulties are that urine is a very complex biological fluid, and that there are a high intra-and inter-individual variability in the protein excretion rate. Progress has been made during the last thirty years, but high analytical variability persists among the colorimetric or turbidimetric methods used for urinary proteins measurement.
Keywords:
measurement methods; urinary protein.
