About this test

The NarcoCheck® CAT rapid test strip is an immunoassay for the fast detection of Khat/Chat use in human urine, via its main marker, the Cathine.

D-norpseudoephedrine, also known as cathine and (+)-norpseudoephedrine, is a psychoactive drug in the chemical class of phenethylamines and amphetamines. Cathine is a drug of abuse of the stimulant class.

Like cathinone, cathine is found in its natural state in Catha edulis, i.e. Khat, a shrub of the Celastraceae family, cultivated in East Africa (Ethiopia) and the south-west of the Arabian Peninsula (Yemen). Consumers chew the leaves for their stimulating and euphoric effects.

To carry out a urine test of Khat/Chat, it is thus the traces of d-norpseudoephedrine which are sought.

Khat is classified as a narcotic and illegal in many countries, including the United States, much of Europe and several African countries.

This urine test of d-norpseudoephedrine (cathine) allows to detect Khat consumption during 1 to 3 days after the intake.
