BugSeq helps many clinical and public health labs to quickly identify pathogens, outbreaks, antimicrobial resistance and more. In order for labs to utilize BugSeq data, they need evidence that the results are both correct and reproducible. Imagine if a system diagnosed the same patient with different conditions depending on what day of the week it was - that system would not be very useful. More concretely, given a set of inputs, a system must produce the same outputs to be useful in a high-stakes setting. Our analysis solutions are no different - labs trust us not only for our accuracy, but also for our reproducibility. It allows them to rely on our results, and many customers have used this property to validate LDTs based on BugSeq. So how do we do it?
