These diagnostic tools are reagent-impregnated strips employed for the qualitative and semi-quantitative detection of various substances in urine. They facilitate the assessment of kidney function, urinary tract infections, carbohydrate metabolism (such as diabetes), and liver function. A typical procedure involves immersing the strip in a urine sample and observing color changes on the reagent pads, which correspond to the presence and concentration of specific analytes.
Their significance lies in their ability to provide rapid, on-site information for preliminary medical evaluations. The immediate feedback allows healthcare professionals to make informed decisions regarding further testing, treatment plans, and patient management. Historically, urine analysis using reagent strips has been a cornerstone of medical diagnostics, evolving from simple visual inspection to technologically advanced colorimetric assays.
