Abstract

A method for determining an analyte concentration in blood is described that reduces the effects of hematocrit using a test strip (100, 300, 400, 500) attached to a test meter (200). The test strip includes a working electrode and a reference electrode. The test meter applies a test voltage between the working electrode and the reference electrode. After a user applies a blood sample containing an analyte onto the test strip, the test meter measures a plurality of test currents for a test time interval. The test meter thereafter calculates an analyte correlation value. An accurate glucose concentration may be determined based on the analyte correlation value.
