Electronic analyte assaying device
First Claim
1. A diagnostic device for detecting the presence of an analyte in a fluid sample, the device comprising:
- a casing having a display;
a test strip mounted in said casing;
a battery mounted in said casing;
a processor mounted in said casing coupled to said battery;
a light source mounted in said casing and operatively coupled to said processor, said light source configured to illuminate a portion of said test strip;
a first sensor mounted inside said casing coupled to said battery and operatively coupled to said processor; and
an opening in said casing through which the first sensor can receive ambient light;
wherein said processor is configured to receive a signal from said first sensor when said device is exposed to ambient light thereby causing said device to become activated.

Abstract
An improved electronic diagnostic device for detecting the presence of an analyte in a fluid sample comprises a casing having a display, a test strip mounted in the casing, a processor mounted in the casing, and a first sensor mounted in the casing and operatively coupled to the processor. The processor is configured to receive a signal from the first sensor when the device is exposed to ambient light thereby causing the device to become activated. The device includes a light shield that exerts pressure across a width of the test strip to prevent fluid channeling along the length of the test strip. The processor is configured to present an early positive test result reading when a measured value exceeds a predetermined early reading threshold value at any time after a predetermined early testing time period.
