Abstract

Assessing test results development during assay analysis is shown and described. In one embodiment, an apparatus generates an assessment of diagnostic test development from an assay. The apparatus may include an optical detector aligned in an optical path with the assay. Further, the optical detector may perform continuous image detection of the assay to generate an assessment testing development. In some examples, the assessment is a graphical display of diagnostic development. In yet other embodiments, a method of assessing diagnostic test development may include signaling the optical detector to perform continuing image detection of the assay and generating an assessment of said diagnostic test development. The assessment may include graphing a reflectance detected on the assay on a display board.

Claims (29)

1. A lateral flow assay system to generate a diagnostic test development from an assay, said system comprising:

a. an incubator configured to incubate said lateral flow assay;

b. a reader configured to detect a first transmission of light on said assay in a stationary imaging position while also being configured to detect at least a subsequent transmission of light on said assay in said stationary imaging position as said system synchronizes said incubator incubating said assay to generate said test result; and

c. a user interface having a graphical display of said diagnostic test development, said graphical display includes a first axis having a measurement of reflectance on said assay and a second axis having a measurement of a remission value of said assay, and whereby said reflectance measurement and said remission value graphically illustrate said diagnostic test development.

2. The apparatus of claim 1 , wherein said graphical display includes a test result assessment about every fifteen seconds.

3. The apparatus of claim 1 , wherein said graphical display includes at least one valley mirroring a line development on said assay.

4. The apparatus of claim 1 , wherein said assessment includes a lowest reflectance point on said assay.

5. The apparatus of claim 1 , wherein said user interface includes an integrated circuit board supporting a display board.

6. The apparatus of claim 5 , wherein said display board includes a graphical display of said diagnostic development.

7. The apparatus of claim 1 , wherein said assay is a lateral flow assay.

8. The apparatus of claim 7 , wherein said assay is a lateral, capillary-flow, elongated test strip.

9. An assay measurement apparatus to generate a diagnostic test development from an assay, said apparatus comprising:

a. an optical detector aligned in an optical path with said assay, wherein said optical detector is configured to acquire a first image detection on said assay in a stationary imaging position while also being configured to acquire at least a subsequent image detection on said assay in said stationary imaging position; and

b. a microprocessor in electrical communication with said optical detector, wherein said microprocessor is programmed to signal said optical detector to synchronize image detection of said assay to generate a graphical display assessment of said diagnostic development.

10. The apparatus of claim 9 , wherein said graphical display illustrates a measurement of reflectance on said assay and a measurement of a remission value on said assay.

11. The apparatus of claim 10 , wherein said graphical display includes a test result assessment about every fifteen seconds.

12. The apparatus of claim 10 , wherein said graphical display includes at least one valley mirroring a line development on said assay.

13. The apparatus of claim 9 , wherein said assessment includes a lowest reflectance point on said assay.

14. The apparatus of claim 10 , wherein said apparatus includes a user interface.

15. The apparatus of claim 14 , wherein said user interface includes an integrated circuit board supporting a display board.

16. The apparatus of claim 15 , wherein said display board includes a graphical display of said diagnostic development.

17. The apparatus of claim 9 , wherein said assay is a lateral flow assay.

18. The apparatus of claim 17 , wherein said assay is a lateral, capillary-flow, elongated test strip.

19. A method of assessing diagnostic test development from an assay, the method comprising:

a. aligning an optical detector in an optical path with said assay;

b. acquiring a first image detection on said assay in a stationary imaging position and acquire at least a subsequent image detection on said assay in said stationary imaging position;

c. signaling said optical detector to perform continuing image detection of said assay; and

d. generating a graphical assessment of said continuing image detection of said diagnostic test development.

20. The method of claim 19 , wherein generating said assessment includes graphing a reflectance detected from said assay on a display board.
