A reagent for use in detecting the presence of aldehyde particularly in an aqueous solution, urine, or other' body fluids comprising a solution sodium metabisulfite, phosphoric acid, basic fuchsin (BA 130) and deionized water. The sodium metabisulfite is present at about 8 - 12 grams, the phosphoric ac id is present at 10 milliliters, the basic fuchsin is present at about 4.8 - 5. 2 grams and the deionized water is present at about 995 - 1005 milliliters. A test kit including a sealed container having a predetermined amount of the reagent therein, a dispenser for obtaining a predetermined amount of a specimen to be tested and depositing it in the container and a color chart f or comparing the color of the combined reagent and specimen after waiting perio d of between 2 - 5 minutes. The method of making the reagent by combining the ingredients and mixing the same for at least 10 minutes and then adding 28 - 32 grams of animal bone charcoal and then stirring the mixture well and allowing it to stand for at least 24 hours and up to 36 hours. Thereafter, t he bone charcoal is removed and the decolorized solution is adjusted for a pH between 1.75 and 1.93 by slowly adding phosphoric acid to the mixture and mixing it well during this procedure. |
