A disposable, enzymatic assay based test strip device 100, 110, 120, 200, 210, 101 for colorimetric detection of an analyte compound, such as ethanol, in a body liquid sample, such as saliva, is provided. The test strip device 100, 110, 120, 200, 210, 101 comprises at least one reactive test zone 2, 2a, configured to develop a visual indication when the concentration of the analyte compound in the body liquid sample exceeds a predetermined limit, and a reactive control zone 3, configured to develop a visual indication upon being supplied with the body liquid sample. The test strip device 100, 110, 120, 200, 210, 101 further comprises a compound buffer 4, preferably selected from non-volatile alcohols and disposed to closely adjoin the reactive control zone 3 such, that the content of the compound buffer 4 admixes with the reagents provided within the reactive control zone 3, while said control zone 3 is being supplied with the body liquid sample. Deposition of the reactive zones 2, 2a, 3 is preferably implemented by conventional printing methods utilizing biological inks. |
