Abstract

A method for assaying a sample involves an assessment device having an assay part and a detachable recording part, which are disposed on separable portions of a substrate. The sample to be assayed is received in a sample application well on the assay element, where it contacts a measuring element, generally after being mixed with an assay reagent. Assay information relating to the sample is transferred from the measuring element to data recording element on the recording part. After the information transfer, the assay part and the recording are separated, so that the assay part can no longer transfer information to the data recording element.

Claims

1. A method for assaying a sample, comprising the steps of:

providing an assessment device having an assay element and a data recording element arranged on a substrate and connected by way of a communication conduit;

receiving a sample within a sample application well on the assay element;

mixing the sample with an assay reagent;

detecting assay information relating to the sample;

transmitting, by way of the communication conduit, the assay information from the assay element to the data recording element;

recording the assay information within the data recording element; and

separating, irreversibly, the communication conduit after the recording step.

2. The method of claim 1, wherein:

the separating step is accomplished by breaking the substrate irreversibly into first and second portions, with the assay element on the first portion and the data recording element on the second portion.

3. The method of claim 2, further comprising the step of:

providing an actuating signal to an indicator upon completion of the recording step.

4. The method of claim 1, further comprising the step of:

providing an actuating signal to an indicator upon completion of the recording step.

5. The method of claim 1, further comprising the step of:

downloading the assay information electronically from the data recording element to a processing facility after the separating step.

6. The method of claim 2, further comprising the step of:

downloading the assay information electronically from the data recording element to a processing facility after the separating step.

7. The method of claim 3, further comprising the step of:

downloading the assay information electronically from the data recording element to a processing facility after the separating step.

8. The method of claim 4, further comprising the step of:

downloading the assay information electronically from the data recording element to a processing facility after the separating step.

9. The method of claim 1, wherein:

the separating step is accomplished by;

inserting the assessment device in a casing; and

breaking the substrate of the assessment device irreversibly into first and second portions, with the assay element on the first portion and the data recording element on the second portion, using a separation line defined by the casing.

10. The method of claim 9, further comprising the step of:

providing an actuating signal to an indicator upon completion of the recording step.

11. The method of claim 10, further comprising the step of:

downloading the assay information electronically from the data recording element to a processing facility after the separating step.

12. The method of claim 9, further comprising the step of:

downloading the assay information electronically from the data recording element to a processing facility after the separating step.
