1. An analyte meter, comprising:
- a housing including a display;
a connector coupled to the housing and configured to releasably receive an in vitro analyte test strip; and
a controller programmed to determine a fill time and an uncorrected analyte value of a sample on an in vitro analyte test strip positioned in the connector, and to determine a hematocrit-corrected value of the analyte using the equation Rc=Rr+((Fill time−
0.4s)*Rr), wherein Rc is the hematocrit-corrected value of the analyte and Rr is the uncorrected value of the analyte.

13. A glucose meter, comprising:
-
a housing including a display for outputting graphical and/or alphanumeric information; a connector coupled to the housing and configured to releasably receive an in vitro glucose test strip; a communication module; and a controller programmed to determine a fill time and an uncorrected glucose value of a sample on an in vitro glucose test strip positioned in the connector and to determine a hematocrit-corrected glucose value using the equation Rc=Rr+((Fill time−
0.4s)*Rr), wherein Rc, is the hematocrit-corrected glucose value and Rr is the uncorrected glucose value.
