Under the Microscope – Kate Stevenson

SWGDAM outlines validation requirements for individual laboratories which include concordance, reproducibility, accuracy and precision, sensitivity and stochastic effects and mixture studies. The details of these requirements are informative but balancing of sample numbers versus robust results to establish conclusions and subsequent guidelines is more tricky.
In her presentation at ISHI, Kate Stevenson (a Senior Scientist at the Institute of Environmental Science and Research Ltd (ESR) will describe the lessons learnt from validation studies at the Institute of Environmental Science and Research Ltd (ESR). The goal being an understanding of the performance of each kit or instrument including its limitations when used on casework like samples.
We sat down with Kate and asked her what considerations a lab should think through prior to starting a validation and the differences between validating quantification kits versus STR amplification kits.
