A system and method for identifying a biological sample associated with a container is disclosed. A universally unique identifier is associated with each container. In one or more embodiments, the identifier comprises one or more markings having a specular reflectance which differs from the specular reflectance of the outer surface of the container adjacent the markings. A detection apparatus detects the differences in specular reflectance light to identify the identifier associated with the container. The identifier is associated with certain information regarding the container and biological sample. From that point forward, any information about the contents of the container may be retrieved by searching on its container ID. Because the container ID is assured by its manufacturer to be universally unique, the container and sample may move from one organization to another under the same identifier, and information about the contents of the container may be shared by querying on its container ID. Practically, the sample ID becomes universal by virtue of presenting a universally-understood search key usable by anyone who needs to process the container. By suitably restricting access to sensitive database fields, patient confidentiality may more easily be assured since the marking on the specimen does not reveal any such information.

The invention claimed is: 1. A system for uniquely identifying a biological sample, comprising: a container having a substantially translucent outer surface having a first specular reflectance; an identifier associated with said container, said identifier comprising a substantially translucent surf

The invention claimed is: 1. A system for uniquely identifying a biological sample, comprising: a container having a substantially translucent outer surface having a first specular reflectance; an identifier associated with said container, said identifier comprising a substantially translucent surface having a second specular reflectance that differs from said first specular reflectance; and a detection apparatus for detecting said identifier based on the difference between said first and second specular reflectances. 2. The system in accordance with claim 1, wherein said detection apparatus comprises at least one light emitter and one light detector. 3. The system in accordance with claim 1, wherein said container comprises a test tube. 4. The system in accordance with claim 1, wherein said identifier comprises at least one marking formed by abrading said outer surface of said container. 5. The system in accordance with claim 1, wherein said identifier comprises at least one marking formed by laser-etching said outer surface of said container. 6. The system in accordance with claim 1, wherein said identifier comprises at least one marking defined by a translucent film material applied to said outer surface of said container. 7. A universally uniquely identifiable container, comprising: an outer surface with an area having a first specular reflectance; and an identifier comprising an area on an outer surface of said container having a second specular reflectance that differs from said first specular reflectance, wherein said area having said second specular reflectance universally and uniquely identifies said container and is substantially translucent. 8. The container in accordance with claim 7, wherein said identifier is universally unique to said container, such that no other container will be assigned the same universally unique identifier. 9. The container in accordance with claim 7, wherein said container contains a biological sample. 10. The container in accordance with claim 7, wherein said first specular reflectance is greater than said second specular reflectance. 11. The container in accordance with claim 7, wherein said container has a top and a bottom and said identifying area extends around said outer surface of said container between said top and said bottom. 12. The container in accordance with claim 7, wherein said container has a top and a bottom and an axis extending through said top and said bottom, and wherein said identifying area has the shape of a bar. 13. The container in accordance with claim 12, wherein said bar extends substantially perpendicular to said axis. 14. The container in accordance with claim 12, wherein said bar extends substantially parallel to said axis. 15. The container in accordance with claim 7, wherein a number of identifying areas are spaced from one another on said outer surface of said container. 16. A system for identifying a biological sample comprising: a container having a universally unique identifier which distinguishes said container from other like containers independently of the contents of said container; a first database for associating information relating to said universally unique identifier with information relating to said container; and a second database for associating information relating to said universally unique identifier with information relating to a biological sample placed in said container. 17. The system of claim 16, wherein said first database stores information regarding the manufacturer of the container. 18. The system of claim 16, wherein said second database stores patient information, biological sample identifying information and date information. 19. The system of claim 16, wherein said identifier comprises an area on an outer surface of said container having a first specular reflectance that differs from an area on an outer surface of said container having a second specular reflectance, wherein said area having first specular reflectance universally uniquely identifies said container. 20. The system of claim 16, wherein said identifier is substantially translucent.
