Chemical Reagent Strip

A chemical reagent strip for screening urine is a narrow band of paper, which has been saturated with chemical indicators for specific substances or properties at various locations on the strip. The position of the test area may vary depending on the brand and type of strip used. Always read the package insert for specific directions.
Notice the relative positions of the test areas and the name of the test that corresponds to each area. The strip should be handled only at the opposite end from the test areas.
