Abstract

Disclosed herein is a method and device for testing an agricultural product for the presence of an unwanted residue including a reader-incubator combination that can utilize onboard motor vehicle systems, such as an onboard microprocessor and onboard power supply.

Claims

1. An apparatus to generate a diagnostic test result from an assay test strip, said apparatus comprising:

a. an optical reader aligned in an optical path with said assay test strip, wherein said optical reader is adapted to acquire an image detection on said assay test strip;

b. a microprocessor in communication with said optical reader, wherein said microprocessor is adapted to signal said optical reader to perform image detection of said assay test strip to generate said diagnostic test result; and

c. a removable module having said assay test strip, an insulated base supporting a test strip cavity, and an optical window positionable between said test strip cavity and said optical reader, and wherein said test strip cavity comprises an optics aperture illuminating said test strip cavity and said removable module blocks debris from contact through said optics aperture to said optical reader in an assembled position, and detaches from said optical reader to expose said optics aperture in a removed position.

2. The apparatus of claim 1, wherein said assay test strip is a lateral flow test strip.

3. The apparatus of claim 2, wherein said removable module includes a repositionable hood to enclose said lateral flow strip.

4. The apparatus of claim 2, wherein said removable module includes at least one aperture adapted to align with a downstream end of said lateral flow test strip.

5. The apparatus of claim 2, wherein said removable module includes a cavity to receive said lateral flow test strip.

6. The apparatus of claim 1, wherein said microprocessor is onboard a motor vehicle.

7. The apparatus of claim 6, wherein said microprocessor interprets data transmission to determine said test result.

8. The apparatus of claim 6, wherein a power source is a power supply integrally associated with said motor vehicle.

9. In a lateral flow test strip assay system having a reader with an optical detector, an insert assembly comprising:

a. a removable module positionable in said reader to align an assay test strip with said optical detector and having said assay test strip, an insulated base supporting a test strip cavity to receive said assay test strip, which is a lateral flow test strip, and wherein said test strip cavity comprises an optics aperture illuminating said test strip cavity and blocking debris from contact through said optics aperture in an assembled position; and

b. a repositionable hood secured to said removable module to enclose said lateral flow test strip.

10. The apparatus of claim 9, wherein said insert assembly being removably positioned in-between said optical detector and said assay test strip.

11. The apparatus of claim 9, wherein said insert assembly being positionable in said reader to block debris from said optical detector.

12. The apparatus of claim 9, wherein said insert assembly is cleanable.

13. The apparatus of claim 9, wherein said insert assembly includes at least one aperture adapted to align with a downstream end of said lateral flow test strip.

14. The apparatus of claim 13, wherein said insert assembly includes a second aperture adapted to align with a coding reference on said lateral flow test strip.

15. An apparatus for testing a quality of an agricultural product to generate a diagnostic test result from an assay test strip, said apparatus comprising:

a. an optical reader aligned in an optical path with said assay test strip, wherein said optical reader is adapted to acquire an image detection on said assay test strip;

b. a microprocessor in communication with said optical reader, wherein said microprocessor is adapted to signal said optical reader to perform image detection of said assay test strip to generate said diagnostic test result; and

c. a removable module positionable in said reader to block debris from said optical detector and having said assay test strip and comprising;

i. an insulated base supporting a test strip cavity to receive said assay test strip,

ii. an optical window positionable between said test strip cavity and said optical reader, and wherein said test strip cavity comprises an optics aperture illuminating said test strip cavity and blocking debris from contact through said optics aperture in an assembled position, and

iii. a hood secured to said removable module to enclose said assay test strip.

16. The apparatus of claim 15, wherein said removable module being adapted to block debris from contact with said optical reader in an assembled position and detached from said optical reader in a removed position.

17. The apparatus of claim 15, wherein said microprocessor is onboard a motor vehicle.

18. The apparatus of claim 15, wherein said assay test strip is a lateral flow test strip.

19. The apparatus of claim 18, wherein said removable module includes at least one aperture adapted to align with a downstream end of said lateral flow test strip.

20. The apparatus of claim 15, wherein said removable module is slide-mounted in said optical reader.
