The KET Test Paper could also detect Ketamine Hydrochloride and Scopolamine Hydrobromide over a concentration range of 1.25 to 10.0 mg/mL.”3rd Party Laboratory CertificationGHBNumber of drinks tested: 41.• Accuracy rate:o Specificity 95.12%o Sensitivity: 95.12%o Overall accuracy: 95.12%• False positives: Milk-based drinks (e.g., milk, Bailey’s) and dark red beverages (e.g.,blackcurrant cordial, red wine) showed potential for false positives due to the reaction of the test paper.• False negatives: Highly acidic drinks (e.g., bitter lemon, lime cordial) did not showconsistent results.KetamineNumber of drinks tested: 85, including a wide range of alcoholic beverages with varying colours, sugar content, and potential cross-reactants.• Significant findings: Most beverages did not interfere with the detection of Ketamine.Exceptions included red wine and dark red liqueurs (e.g., blackberry and raspberryliqueurs), where detection required higher concentrations.• Accuracy: No false negatives were recorded across the beverages tested.o Specificity 100%%o Sensitivity: 97.67%o Overall accuracy: 98.84%• False positives: Dark red beverages (e.g., blackcurrant cordial, red wine) showedpotential for false positives due to the reaction of the test paper.• False negatives: None.
