A sample Tracking System to Automate and Increase
Workflow in a Forensic DNA Lab
Dustin Foley, MS
AFDAA 2012 Winter Meeting
• Goals
– To create a system that tracks the processing steps of a sample
– To fully use the capabilities of our instruments
– To have a continuous workflow and eventually have it all in one system and to go paperless.
– Increase efficiency in laboratory
– Decrease processing error
• Process Efficiency
– Reduce having to retype case # and sample #
– Reduce manual verifications of paperwork
– Reduce time in manually preparing import sheets for the robots
• Reduce/ Eliminate Processing Error
– Eliminates analyst from manually typing and writing samples incorrectly
– Eliminates sample switches
– Prevents evidence from being processed incorrectly in a batch system
Serology to Report Writing
• Brief overview of the process – Barcode system/Excel Workbooks
• Serology
• Extraction
• Quantification
• Amplification
• Electrophoresis
– SQL Database • Report Writing
• QC Database entry
• CODIS upload
Overview
• Reduces/Eliminates Error
– Sample #
• Is only entered once and is used from serology to report writing.
– Instruments
• No errors in typing samples into runs on instruments
• No errors in sample switching or processing known and reference samples simultaneously
• No error in analysts mistyping profiles into case files or into CODIS
Overview
• Increase Efficiency
– Except for initial verification entering sample name in serology, all other verifications are done in barcode system
– Barcode system/SQL Database/ Excel Templates are now all linked together
• This allows all instruments to flow in a seamless process through exporting and importing files
• Reduces manual typing of information
This is only the beginning
• Future Goals
– Writing reports in the SQL Database
– Adding serological testing
– Convert all excel workbooks into the SQL Database to further seamless process
– Going paperless
