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. A disposable assay device, comprising:

a plurality of first carrier parts coupled to each other, each first carrier part having a respective sample-receiving area for receiving a sample to be tested;

at least one second carrier part coupled to the at least one of the plurality of first carrier parts for performing the assay of the samples and forming assay data; and

a transmitter for transmitting assay data to a remote receiving system,

wherein at least one of the plurality of the first carrier parts is independently removable from the second carrier part and the remaining plurality of the first carrier parts.

2. The assay device according to claim 1, wherein the plurality of first carrier parts is an array of first carrier parts detachably coupled to each other.

3. The assay device according to claim 1, wherein the plurality of the first carrier parts are each detachably coupled to the second carrier part.

4. The assay device according to claim 1, further comprising weakening lines or perforation lines extending between the first and second carrier parts for independently removing the first carrier parts from the second carrier part.

5. The assay device according to claim 1, wherein the at least one second carrier part includes a memory device and is configured to record each assay result in combination with identification information of a respective first carrier part, leading to that assay result, in the memory device.

6. The assay device according to claim 1, wherein the at least one second carrier part includes a memory device and is configured to record each assay result in combination with time information concerning a respective assay, leading to that assay result, in the memory device.

7. The assay device according to claim 1, wherein the at least one second carrier part includes a memory device and is configured to detect the removal of a first carrier part, and to record a time of the removal of the first assay part, in the memory device.

8. The assay device according to claim 1, wherein the first and second carrier parts are configured to assay at least two blood samples, provide at least one assay result, and carry out an oral glucose tolerance test.

9. The assay device according to claim 1, further comprising a test-ready indicator on at least one of the plurality of first carrier parts.

10. The assay device according to claim 1, wherein the second carrier part includes a user interface having multiple-choice buttons.

11. The assay device according to claim 1, wherein the second carrier part comprises a memory device configured to store assay results relating to tested samples, and a controller.

12. A method of assaying, the method comprising acts of:

providing a disposable assay device including a plurality of first carrier parts coupled to each other and a second carrier part coupled to at least one of the first carrier parts;

applying one or more samples to a selection of the first carrier parts to test the samples for the presence of one or more analytes;

storing resulting test results in a memory; and

removing each first carrier part of the selection from the plurality of first carrier parts and second carrier part after having used that selection of the first carrier parts.

13. The method according to claim 12, wherein first carrier parts are used in sequence, with a predetermined intermediate time period of approximately 24 hours.

14. The method according to claim 12, further comprising an act of:

transmitting assay data to a remote receiving system, the assay data comprising one or more assay results information concerning failure of the assaying.

15. The method according to claim 14, wherein the receiving system receives the assay data and determines, using the received assay data whether a respective assay data is a negative or positive assay result, whether the assay result is inconclusive, whether the assaying has failed, and why the assaying has failed.

16. A disposable assay device to assay one or more samples, the disposable assay device comprising:

a plurality of sample application areas removably coupled to each other for receiving the one or more samples to be assayed;

a controller detachably coupled to at least one of the plurality of sample application areas for performing the assay of the one or more samples and forming assay data;

a transmitter for transmitting the assay data to a remote receiving system; and

one or more assay context sensors to monitor one or more assay context factors

wherein at least one of the plurality of sample application areas is independently detachable from the controller and the remaining plurality of sample application areas.
