Slides: Organization Distribution and Filing

An often overlooked and very necessary part of the lab is storing specimens. This was the job of the laboratory aides in the lab that I worked in. It takes a tremendous amount of time to make an efficient system for dealing with the flow of specimens we received while working at the lab at Caris Lifesciences.

The organization flow started when the specimen entered the company where it was given a case number. This number was used for all of the logging that occurred when the specimen passed through all the steps up to the case report. At any time, we could track where a case was based on the fastidious logging at each station.  Because the life of someone is on the line, these logging steps prevent the mix up of tissue from one patient to the next. There are also a lot of auditing that goes on to make sure everything was where it should be. The laboratory information system (LIS) and sharepoint were some of the tools used for data logging and mining.

The lab aide spent most of their time moving slides around the laboratory. This distribution is key to efficient turn around time (TAT). We prided ourselves at Caris, that we could get a specimen in, and provide all the work required to make a good therapy regime,  with a window of only 7 days or less. If all of the machines were operating and there were no holdups, this happened most of the time. Sometimes machines would go down or an antibody would not work properly, which would really slow the process down. At this point, the organization and distribution of the slides are key to making sure that everything gets done in the order it is suppose to.

Laboratory Information System (LIS)

The laboratory information system (LIS) is a system used in a laboratory to track everything that happens in a lab. Most companies use a combination of paper and electronic logs to track everything from specimen arrival to machine maintenance. Storing the information of what happened to a specimen as it goes through the lab is not only essential, but are required by most laboratory accreditation organizations.

While I worked for Caris Lifesciences, every single thing we did in the lab was tracked via LIS, MS Sharepoint, or by pen and paper logs. This was key to being able to find cases if there were problems at any point during the process. Dutiful use of these systems provide many audit points to make sure nothing is lost in the process, and if something does go missing, this provides a great starting point to finding it. There are also many points during the process that mistakes in labeling or specimen handling can be caught before they become a problem.

Another product of using a system that tracks everything is that you get to run statistics on how the process is working. This can allow further refinements to streamline efficiency. With all that data at your disposal significant findings can be found by data mining.
