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 acid 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 for comparing the color of the combined reagent and specimen after waiting period 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, the 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. |
