Laboratory Tests

There's no good way of showing this chart without enlarging it, but I wanted to share it on this blog because it is a somewhat mindboggling display of normal ranges for laboratory values for an array of tests. I really like it as it captures some of the complexity of medicine in knowing when to send all these tests and how to respond to the results. Surprisingly, after doing a bit of medicine, many of these reference ranges feel intuitive.
