Abstract

Disposable assay device, comprising a carrier having a first carrier part (3) with a respective sample-receiving area (w) for receiving a sample to be tested, and having at least a second carrier part (9), the assay device being configured for transmitting assay data or information to a remote receiving system (20), and the device comprising at least two first carrier parts, said first carrier parts (3, 5) being independently removable from the second carrier part (9).

Claims

1. Disposable assay device, comprising a carrier having a first carrier part (3) with a respective sample-receiving area (w) for receiving a sample to be tested, and having at least a second carrier part (9), the assay device being configured for transmitting assay data or information to a remote receiving system (20), characterized in that the device comprises at least two first carrier parts, the first carrier parts (3, 5) being independently removable from the second carrier part (9).

2. Assay device according to claim 1, comprising an array of first carrier parts (3, 5), the first carrier parts (3, 5) being detachably coupled to each other.

3. Assay device according to claim 1, wherein at least two of the first carrier parts (3, 5) are each detachably coupled to the second carrier part (9).

4. Assay device according to claim 1, the carrier comprising weakening lines or perforation lines (L) extending between the first and second carrier parts (3, 5, 9) for independently removing the first carrier parts from the second carrier part.

5. Assay device according to claim 1, configured to record each assay result in combination with identification information of a respective first carrier part (3, 5), leading to that assay result, in a memory device (10).

6. Assay device according to claim 1, configured to record each assay result in combination with time information concerning a respective assay, leading to that assay result, in a memory device (10).

7. Assay device according to claim 1, configured to detect the removal of a first carrier part (3, 5), and preferably configured to record a time of the removal of the first assay part, in a memory device (10).

8. Assay device according to claim 1, configured to assay at least two blood samples, and to provide at least one assay result relating to the assaying of the one or more samples, wherein the assay device is configured to carry out an oral glucose tolerance test (OGTT).

9. Assay device according to claim 1, wherein the second carrier part is provided with a test-ready indicator.

10. Assay device according to claim 1, wherein the second carrier part is provided with a user interface, preferably, comprising multiple-choice buttons.

11. Assay device according to claim 1, wherein the second carrier part comprises a memory device (10) configured to store assay results relating to tested samples, and/or a controller (8).

12. Assay method, utilizing at least one device according to claim 1, comprising:

applying one or more samples to the first carrier parts (3, 5) of the device to test the samples for the presence of one or more analytes;

storing resulting test results in a memory of the device; and

removing each first carrier (3, 5) part from a remaining device part after having used that first carrier part.

13. Method according to claim 12, wherein first carrier parts (3, 5) of the device are used in sequence, with a predetermined intermediate time period, for example approximately 24 h.

14. Method according to claim 1 comprising:

transmitting assay data or information to a remote receiving system (20), the assay data or information relating to, being based on and/or comprising one or more assay results of the assay devices (1) and/or comprising information concerning failure of the assaying.

15. Method according to claim 14, wherein the receiving system (20) receives the assay data or information and determines, using the received assay data or information, whether a respective assay result of an assay device is a negative or positive assay result, and/or whether the result is inconclusive, and/or whether the assaying has failed, and optionally a/the reason(s) why the assaying has failed.
