To use.. Remove test device from protective wrapper. Place tesgt on a clean and level surface. Fill the dropper with urine. Carefully drop approximately 3 drops of urine into the specimen well (S) of the test device and wait for the colored line(s) to appear. Results will take 5-10min to appear. The control line (C) will usually appear darker than the Test line (T). The shade of color of the T line may vary, but it should be considered negative whenever there is even a faint line. If the C line does not form, the test is invalid. For best results, use first morning urine.
