Test kit for detecting acetylcholinesterase inhibitors

A test kit for detecting organophosphate compounds, comprising:

• a support apparatus having an upper side and an underside, a sampling device, a buffer solution in a sample tube having a cap, and an acetylcholinesterase as the first active component, and a mixture of 5,5′-dithiobis(2-nitrobenzoic acid) (DTNB) and acetylthiocholine, wherein the sampling device is packaged in a sample tube having a cap, the first active component is applied in a first reagent cap and the second active component is applied in a second reagent cap, and the first and second reagent caps each close a sample tube, wherein the support apparatus has at least four fixing devices for receiving the sample tubes, wherein the fixing devices are formed by recesses in the support apparatus, the sample tubes are fixed parallel to the upper side of the support apparatus, and wherein the support apparatus has at least two receiving devices for receiving the first and the second reagent caps and a receiving device for vertically receiving a sample tube.
