The CYD test tests for minimal standard dosages of Ketamine and GHB (gammahydroxybutrate) in drinks. Smaller quantities may not be detected.  Some substances, such as those red in colour, or milk, may produce a ‘false positive’.  Follow the instructions exactly.  Place the drink sample on the test strip. Do not place test strip in the drink.  A drink producing a negative result could still be unsafe as it may contain dangerous substances other than those tested for.  If in doubt, do not consume the drink.

Store the test strips away from children, animals, chemicals and moisture. The manufacturer does not make any representation or warranty save as specifically set out above, cannot be held responsible for the presence of any substance other than as specified above, and excludes all liability for consequential and all other loss to the extent permitted by law.  The manufacturer’s liability for a defective product is limited to replacement or refund of the purchase price. Your statutory rights are not affected.
