Urine is an easily accessible biological fluid. This availability makes it tempting for a direct analysis of urinary parameters by physicians. Urinary proteins, that are interesting markers for several pathologies, are detected by urinary strips, rapidly and at a low cost. However, to ensure an optimal use of urinary strips, one may be familiar to their characteristics and their limits. This paper details the available urinary strips used for the detection of urinary proteins and urinary albumin, as well as their analytical performances in clinical conditions such as pregnancy, chronic renal disease, diabetes or for the screening of general populations.
Keywords: urinary albumin; urinary protein; urinary strips.
