Re: Interpreting a covid-19 test result

Dear Editor,

It would be good if you could change the data entry fields to allow floating point numbers, since the Specificity is actually probably around 99.9% and you can only enter 99%. I guess you'd need to increase the sample size to 10,000 or something as well. The tool could be used better to reflect the current situation then.

It's a very cool tool though, well done!
