摘要： A test system for measuring analyte concentration in a fluid sample includes: (i) a capillary-fill biosensor (20) having a working electrode (24), a reference electrode (22) and a separate counter electrode (23), arranged such that a fluid sample which flows evenly along the capillary flow path will substantially completely cover the reference electrode (22) before the fluid sample makes contact with any part of the counter electrode (23); and (ii) a test meter (42) for receiving the biosensor (20), the meter (42) including: first signal circuitry (31) for producing a first signal when an electrical circuit is detected between the reference electrode (22) and the working electrode (24); second signal circuitry (33) for producing a second signal when an electrical circuit is detected between the counter electrode (23) and at least one of the reference electrode (22) and the working electrode (24); a timer (35) for determining the time interval between production of said first signal and said second signal; and a processor (32) for triggering an error condition if said time interval exceeds a preset value or if said second signal is not produced within a preset time after said first signal is produced.
