Abstract
A method is provided for analyte measurement by a user using an analyte measurement device. An analyte measurement is provided with a plurality of penetrating members and analyte sensors. Each analyte sensor is positioned in a sample chamber with a volume no greater than 1 μl. Each sample chamber has a working electrode, reference electrode and a counter electrode. The working electrode has a conductor, an enzyme and a mediator. A penetrating member and an unused analyte detecting member are presented into an active position. The following steps are then performed: (a) the penetrating member is fired to prick the skin and bring a fluid sample to the analyte detecting member, (b) the analyte level is measured, and (c) it takes no more than 10 seconds from the step of presenting the penetrating members and unused analyte into the active position through the step of measuring the analyte level.
