Abstract
A method for coding and identification of biological samples for in vitro fertilisation comprises the steps of applying to receptacles intended for unfertilised eggs and sperm, respectively, an identification code characteristic of the patient; placing unfertilised eggs and sperm, respectively, in the receptacles; storing, transporting and admixing the respective samples in receptacles which each carry the same code; and implanting the resulting embryo in the patient. The identification code may based on RFID technology, in which sample vessels (12) are codified by the application of an RFID tag (13).

Apparatus for identification of biological samples for in vitro fertilisation, the apparatus comprising storage vessels associated with an identification code, the identification code being based on RFID technology, sample vessels being codified by the application of an RFID tag;
- the apparatus comprising:
- a surface defining a work area;
- a reader to read the RFID tag;
- an antenna for transmission of activation radiation and receiving signals emitted by the RFID tag, the antenna located below the surface;
- a resistor to dampen the magnetic field produced by said antenna sufficient to prevent the RFID tag being swamped and still allow communication between the antenna and the RFID tag;
- a transformer to provide power to the antenna, the transformer configured to minimise any impedance mismatch between the reader and the antenna;
- and
- an adjustable capacitor to tune to resonance the coupling between the antenna and the RFID tag over the surface of the laboratory bench.
