Patent ID: 7740805

Claim:
A method of manufacturing a device used for analysis of a fluid sample, the method comprising: forming a trench in a substrate to form a sample reservoir configured to receive the fluid sample, a reagent reservoir configured to contain a reagent, a mixing reservoir including a chamber configured to receive and mix the fluid sample and the reagent to form a mixture, and channels between the sample reservoir, the reagent reservoir, and the mixing reservoir; placing at least a portion of a sensor within the chamber, the sensor configured to sense, within the chamber, a measurable property of the mixture to generate a test result, wherein the measurable property is a property selected from a group of properties that includes a chemical property of the mixture, a physical property of the mixture, and an electrical property of the mixture; and coupling a processor to the sensor, wherein the processor is integrally formed with the substrate and is configured to analyze the test result.
