Abstract

Sample specimens such as biological samples are collected from the donor at a collection site and transferred to a transport container which includes RFID medium for carrying the chain of custody information generated at the collection site. The electronic signature of the donor and/or collector is captured to verify the chain of custody information and is included in the RFID medium record. Tamper-evident medium is used to insure the integrity of the sample specimen. The RFID medium may be separated from the container and recycled for subsequent use.

Claims

1. Method for specimen and sample chain of custody tracking comprising the steps of:

collecting a desired sample from a donor at a collection site;

placing the collected sample in a transport container uniquely identified by information in an RFID medium;

generating chain of custody information;

writing chain of custody information to the RFID medium;

reading chain of custody information from the RFID medium at a sample testing site;

processing the collected sample in accordance with the sample testing site operating procedures; and

erasing the chain of custody information from the RFID medium.

2. The method of claim 1, wherein the step of writing chain of custody information includes the step of writing the donor'"'"'s electronic signature to the RFID medium verifying the chain of custody information.

3. The method of claim 1, wherein the step of writing chain of custody information includes the step of writing the collector'"'"'s electronic signature to the RFID medium.

4. The method of claim 1, further including the step of affixing the RFID medium to the transport container.

5. The method of claim 1, further including the step of providing a tamper-evident detection means to the RFID medium.

6. The method of claim 1, further including the step of generating the chain of custody information using voice recognition apparatus.

7. The method of claim 1, further including the step of generating the chain of custody information by computer data entry.

8. The method of claim 1, further including the step of recycling the RFID medium for subsequent use and erasing the chain of custody information from the RFID medium.

9. The method of claim 1, wherein the step of generating the chain of custody information includes generating demographic information specific to the donor.

10. The method of claim 1, further including the step of storing the collected sample and transport container for a predetermined time interval.

11. A specimen and sample chain of custody tracking system comprising:

means for collecting a desired sample from a donor at a collection site;

means for placing the collected sample in a transport container uniquely identified by information in an RFID medium;

means for generating chain of custody information;

means for writing chain of custody information to the RFID medium;

means for reading the chain of custody information from the RFID medium at a sample testing site;

means for processing the collected sample in accordance with the sample testing site operating procedures; and

means for erasing the chain of custody information from the RFID medium.

12. The specimen and sample chain of custody tracking system as defined in claim 11 further including means for writing the donor'"'"'s electronic signature to the RFID medium verifying the chain of custody information.

13. The specimen and sample chain of custody tracking system as defined in claim 11 further including means for writing the collector'"'"'s electronic signature to the RFID medium.

14. The specimen and sample chain of custody tracking system as defined in claim 11 further including means for affixing the RFID medium to the transport container.

15. The specimen and sample chain of custody tracking system as defined in claim 11 further including means for providing tamper-evident detection means to the RFID medium.

16. The specimen and sample chain of custody tracking system as defined in claim 11 further including means for recycling the RFID medium for subsequent use and means for erasing the chain of custody information from the RFID medium.

17. Method for specimen and sample chain of custody tracking comprising the steps of:

providing relevant donor information and testing information at a collection site;

opening a collection kit in the presence of the donor;

verifying the RFID medium is secured to the transport container in the collection kit;

collecting a desired sample specimen from the donor in accordance with the testing information;

placing the collected sample specimen in the transport container uniquely identified by information in the RFID medium;

verifying tamper-evident medium in place on the transport container and operating;

verifying the sample specimen collection and capturing the electronic signature of the collector;

reviewing and verifying the donor information and testing information and capturing the electronic signature of the donor;

writing the donor information, testing information, and donor and collector electronic signatures to the RFID medium;

inspecting the transport container and tamper-evident medium at a sample testing site;

reading the donor information, testing information and electronic signatures of the donor and collector attesting the integrity of the donor information and collected sample specimen;

generating accession identification means and applying to transport container;

processing the collected sample specimen in accordance with sample testing site operating procedures;

saving the transport container with the collected sample specimen for a predetermined time interval;

removing the collected sample specimen from the transport container after the predetermined time interval has passed;

separating the RFID medium from the transport container;

erasing information contained in the RFID medium;

sanitizing the RFID medium for re-use.
