Claim:
1. A device configured to perform an immunoassay for a target analyte in an amended urine sample, the device comprising: a first region comprising reagents for of amending a urine sample, wherein the reagents comprise a water soluble protein for blocking non-specific binding of immunoglobulins at a sensor and a buffer; and a second region comprising: (i) a capture molecule capable of binding to the target analyte bound to a conjugate molecule labeled with an enzyme to form an immunocomplex, and (ii) the sensor comprising at least one electrode configured to detect the immunocomplex and determine a concentration of the target analyte in the amended urine sample, wherein the first region is configured to provide a dissolved concentration of the water soluble protein within the amended urine sample in a range of about 0.02 to 225 mg/mL; and wherein the reagents further comprise a scavenger for reducing non-specific current generation from electroactive species at the at least one electrode.
