First Claim
Patent Images
1. A method of testing a fluid sample held by a device comprising:
- a fluidic element; and
an RFID tag, the RFID tag comprising an antenna, the antenna having a shape configured to enclose at least a portion of a space, wherein at least a part of the fluidic element is located in the space, the method comprising;
coupling the device to a reader,testing the fluid sample held in the device,reading calibration information of test materials used for the testing of the fluid sample by the device and data of the fluid sample from the RFID tag via the antenna;
adjusting the calibration information based upon a length of time between assembly of the device and use of the device; and
adjusting read data of the fluid sample in accordance with the adjusted calibration information.

Abstract
A device such as a disposable cartridge has an RFID tag (30) having an antenna (10), and a fluidic element (20, 160), the antenna having a shape to at least partly enclose an area, at least a part of the fluidic element being located in this area. By having such a structure, the device can be made more compact or the antenna can be made larger, and hence the costs for a given performance can be reduced, or the storage space for a given number of devices can be reduced.
