Abstract

Systems, methods, and apparatus are described for the handling of biological specimens for analysis. The systems, methods and apparatus are designed to reduce errors in misidentification, incorrect processing, and recordkeeping and reporting. The systems, methods, and apparatus can also provide real time tracking of samples at any stage, from collection to processing to analyzing to storage.

Claims

1. A method for configuring a device controlling at least one instrument in a laboratory comprising:

configuring said device to store at least one item of device information, wherein the at least one item of device information is input to or generated by the device;

configuring said device to store at least one item of central information wherein at least one copy of the at least one item of central information is stored in at least one other device,

wherein at least one of the items of central information and device information are used by said device in connection with processing performed by said at least one instrument;

configuring said device to identify a carrier in said laboratory;

receiving, by a label associated with said carrier, a signal from a label scanner; and

transmitting, by said label in response to said signal from said label scanner, an electromagnetic response signal including a unique identifier for uniquely identifying said carrier in said laboratory.

2. The method of claim 1, wherein said device and said at least one other device communicate with a central server to maintain an up-to-date local copy of said at least one item of central information.

3. The method of claim 2, further comprising:

configuring at least one item of device information as a new item of central information;

communicating said new item of central information to said central server; and

configuring said at least one other device in accordance with said new item of central information using said central server.

4. The method of claim 1, wherein said device, said at least one other device and said central server are included in a laboratory network.

5. The method of claim 4, wherein said central server is connected to a laboratory information system.

6. The method of claim 1, wherein said laboratory instrument is an anatomical pathology laboratory instrument.

7. The method of claim 4, wherein said device performs offline processing with respect to said at least one other device and said central server, and said device uses said at least one item of device information in said offline processing with said at least one instrument.

8. The method of claim 7, wherein said device synchronizes said at least one item of central information with said central server when said device completes said offline processing, said device and said at least one other device being configured to use different items of central information.

9. The method of claim 1, wherein said at least one item of central information includes the unique identifier and a protocol.

10. The method of claim 1, wherein said configuring said device to identify a carrier includes using a symbology used with optical encodings in the laboratory.

11. The method of claim 10, wherein one of said instruments controlled by said device operates in accordance with said symbology.

12. The method of claim 11, wherein an optical scanner is one of said instruments controlled by said device, said scanner supporting scanning operations in accordance with said symbology.

13. The method of claim 11, wherein a printer is one of said instruments controlled by said device, said printer supporting printing operations in accordance with said symbology.

14. The method of claim 11, wherein said label is a bar code label associated with said carrier, and said symbology is used with said bar code label in connection with processing within the laboratory.

15. The method of claim 14, wherein said bar code label encodes an identifier used to obtain data from a database about said carrier associated with said bar code label, said data including at least one of said items of central information and of device information.

16. The method of claim 1, wherein said electromagnetic response signal is produced using information encoded in said label associated with said carrier.

17. The method of claim 1, further comprising:

determining a location of said carrier in said laboratory in accordance with said electromagnetic response signal.

18. The method of claim 1, wherein said label is affixed to a surface of said carrier.

19. The method of claim 1, wherein said label is embedded in said carrier.

20. The method of claim 19, wherein said label includes optically recognizable data which is readable by a machine.

21. The method of claim 1, further comprising:

using said unique identifier to obtain additional information about said element from a database.

22. The method of claim 1, wherein said devices, a central server, and a laboratory information system are included in a laboratory network, said laboratory information system in communication with said central server, and said central server is in communication with said device.

23. A system for laboratory information management and control comprising:

a laboratory information system having patient and laboratory information,

a first device configured with an item of device information and configured to share an item of central information, said item of device information being input to or generated by the device, said device using at least one of said items of central information and of device information in connection with performing processing on at least one laboratory instrument connected to said first device;

said first device being further configured to identify a carrier in said laboratory, receive, by a label associated with said carrier, a signal from a label scanner, and transmit, by said label in response to said signal from said label scanner, an electromagnetic response signal including a unique identifier for uniquely identifying said carrier in said laboratory;

a second device configured to share said item of central information;

at least one laboratory instrument controlled by said device; and

a server in communication with said laboratory information system and said at least one device, said server managing a database including said item of central information, said server communicating with said first device and said second device to maintain a current copy of said item of central information in said database, and local copies of said item of central information at each of said devices.
