Abstract: A device combining a fuel-cell-type breathalyzer with an electrochemical saliva drug test. The saliva drug tester comprises a disposable test strip-electrode module assembly and an analyzer module. The saliva is squeezed out of an absorbent swab when the test strip is inserted into the electrode module. The electrode module can also carry information that is read and evaluated by the analyzer, e.g. for verification of the electrode module.

Abstract: A fluid assay system comprises a swab having an absorbent portion for receiving and retaining a fluid sample. The system also comprises an electrode module having at least one electrode, arranged so that it can be selectively placed over the absorbent portion of the swab in order to contact the electrode with the fluid sample. The system further comprises a reader module configured to process signals from the electrode module, with the electrode and reading modules arranged such that they can be coupled together for communication of the signals from the electrode module to the reader module.
