Efficient Validation Using STR-validator
Validation of new STR typing kits are often time consuming which can delay implementation of new technology. STR-validator is a free open-source software tool designed to help forensic genetic laboratories evaluate the data. Lectures and demonstrations will exemplify experimental design and efficient evaluation. Examples will highlight quality control of the data and result. The goal is to introduce STR-validator as an efficient tool to analyze validation data in accordance to ENFSI recommendations/SWGDAM guidelines.
Learning Outcomes
Understanding of the STR-validator framework and its possibilities
Validation according to ENFSI recommendations/SWGDAM guidelines
Documentation and interpretation of the validation result
