For example, imagine a patient comes in for a reported seizure. What lab tests do you order? Should you check their tongue for bites? What does it mean when the EEG results are negative? Can brain imaging be helpful?

This powerful tool can answer those questions for hundreds of conditions. It suggest tests that you might not have considered. It facilitates evidence based decision making. It's a great learning tool for medical students. It saves time and money by eliminating unnecessary tests.

Our methodology:

1) We used peer-reviewed papers that performed meta-analysis whenever possible

2) Some tests have only been studied once, so we cited that paper if it was a high quality study

3) If no meta-analysis had been performed, and there were multiple studies performed, we looked at the quality of the studies, how respected the journal was, and how recent the data was collected.

Ratings and Reviews

A good idea but needs serious work


Wide variety of tests included but I can't trust or use the sensitivity/specificity numbers when each test's characteristics appear to be drawn from a single article. Test characteristics vary, often widely, between studies. And the population in which the test was used dramatically affects ppv and npv. I would love to have a reference like this but it would need to include results of multiple studies and information about the populations and the gold standards used to evaluate each test in order to be really usefule.

Great app!


It's about time something like this was made--I wish I had it for my 3rd year IM rounds. The highlight of this app is that it references meta-analyses, review articles, and big studies from big journals so I trust the numbers presented. The user interface is OK, and I hope they'll make it a little easier to navigate in future updates. All in all a terrific app!

thorough, quality info.


This is a really helpful app, not just for impressing on wards but for actually helping patients. It looks all the references are from meta-analyses (compilations of multiple studies) or from the "gold-standard" studies published in NEJM, the Lancet, etc.
