1. A diagnostic assay system comprising:
- a test device including a test strip having one or more test lines and one or more indicia, and a scanning device comprising;
i) a source of electromagnetic radiation;
ii) an optics assembly disposed to direct the electromagnetic radiation;
iii) a detector disposed to receive an emission or reflection from the test strip, wherein;
the detector is a single detector configured to detect the emission or reflection from the one or more test lines and emission or reflection from the one or more indicia;
orthe detector comprises a first detector configured to detect the emission or reflection from the one or more test lines and a second detector configured to detect the emission or reflection from the one or more indicia;
iv) a microprocessor; and
v) a chassis;
wherein the test device and scanning device are configured to be movable relative to each other during operation of the scanning device and wherein the microprocessor is configured to generate test result data based at least in part on the indicia and one or more of the test lines.

Abstract
A diagnostic assay system including a test device and a scanning device are described. In one implementation, the scanning device includes a source of electromagnetic radiation, an optics assembly, a detector, and a microprocessor disposed within a chassis. The test device and scanning device may be configured to be movable relative to each other during operation of the scanning device.

16. A method of assaying a sample to detect an analyte of interest, the method comprising the steps of:
-
providing a sample from a sample collection device to a test device, wherein the test device comprises one or more test lines having immobilized thereto a capture moiety specifically binding directly or indirectly one or more analytes of interest, and wherein one or more indicia are positioned on a surface of the test device adjacent the one or more test lines; moving the test device relative to a scanning device; reading one or more of the test lines and one or more of the indicia, said reading further comprising; detecting emission or reflection from the one or more test lines and from the one or more indicia at a single detector of the scanning device;
ordetecting emission or reflection from the one or more test lines at a first detector of the scanning device and detecting emission or reflection from the one or more indicia at a second detector of the scanning device; generating test result data based at least in part on the reading; and storing the test result data in a memory. - View Dependent Claims (17)
