DRI™ Gravity Detect Reagent, 6 x 18 mL

The DRI Gravity-Detect Test is intended for the quantitative determination of human urine-specific gravity. Many drug users attempt to evade detection by adulterating their specimens in order to produce false-negative results during the initial immunoassay screening. Adulteration methods include dilution with water, substitution with a drug-free liquid, the addition of readily available household materials (e.g., vinegar, baking soda, liquid drain opener, detergent, etc.), or tampering with certain chemicals (e.g., Urine-Aid, which contains glutaraldehyde, or Klear, which contains potassium nitrite). Several methods have been used to detect urine adulteration.
