Beschreibung
Zusammenfassung:	A test strip for measuring the blood alcohol content from blood includes a base material and two electrodes attached to it and a reaction area connected to both electrodes, to which area nicotin-amide adenine dinucleotide (NAD+) and alcohol dehydrogenase enzyme (ADH) are applied as reagents. A sample opening is connected to the reaction area, from which opening the blood sample to be measured can be transferred to the reaction area to dissolve the reagents and optional auxiliary substances, and at the same time into contact with both electrodes. Between the electrodes can thus be formed a potential difference which makes possible the movement of the protons (H+) formed in the reaction towards a negatively charged working electrode, whereby a measurable change in current is formed. The invention further relates to an apparatus and method for measuring the blood alcohol content from blood.
