SENSORS HAVING INTERNAL CALIBRATION OR POSITIVE CONTROLS

摘要

Analyte-detecting sensor devices include a test sensor, a reference sensor and one or more positive control or calibration sensors. The sensors are in fluid communication with each other. For example, the sensors may be positioned in and in fluid communication with a flow path of the sensor device.

主权项

1. A device for detecting an analyte in a sample, comprising:
one or more test sensors configured to bind the analyte; one or more control sensors comprising bound analyte or analyte analog, wherein each control sensor comprises a known amount of bound analyte or analyte analog prior to performing an assay to detect the analyte in the sample; a fluid flow path for carrying the sample, wherein the one or more test sensors and the one or more control sensors are positioned along and in communication with the fluid flow path; and control electronics operably coupled to the one or more test sensors and the one or more control sensors, wherein the control electronics are configured to compare signals generated from the one or more test sensors and the one or more control sensors to determine an amount of analyte present in the sample.
