Abstract: The present disclosure provides a test strip including: a conductive pattern formed on a substrate, the conductive pattern being formed from a thin film material, the conductive pattern including: a plurality of electrodes configured to perform a reagent-free measurement of hematocrit levels in a blood sample; a plurality of conductive contacts configured to communicate with a test meter; and a plurality of conductive traces configured to electrically connect the plurality of electrodes to the plurality of conductive contacts; an inert layer positioned on at least a portion of the conductive pattern; and a capillary chamber exposing at least a portion of the plurality of electrodes, the capillary chamber being defined by the inert layer for receiving a blood sample and delivering the blood sample to the plurality of electrodes.

Abstract: A test strip comprising a base layer, the base layer having an optional hematocrit anode configured to determine a value corresponding to a hematocrit level of a fluid sample, wherein the hematocrit anode may be coated with a reagent, an interference anode configured to determine a value corresponding to a measurement of an interference caused by one or more oxidizable substances in the sample fluid, wherein the interference anode electrode includes an interference reagent on its surface, a glucose anode, the glucose anode being configured to determine a glucose level in the fluid sample, wherein the glucose anode is covered with a reagent comprising a mediator and an analyte specific enzyme, and one or more cathodes in a cooperative relation with the hematocrit anode, the interference anode, and the glucose anode to measure the hematocrit level, the interference and the glucose level.

Abstract: Methods and devices for determining the concentration of a constituent in a body sample are provided. The body sample is introduced into a biosensor having a sample chamber and at least part of an electrode disposed therein. The biosensor also includes an alginate hydrogel substantially covering a portion of the sample chamber. The alginate hydrogel substantially includes an alginate polymer configured to reduce cellular migration.

Abstract: Cholesterol from Low Density Lipoproteins (LDL-C) is measured directly with a test strip at room temperature using a reagent that takes advantage of the varying surface charge density on LDLs and non-LDLs to selectively make LDL-C available for testing.
