Hands Down Best Medical Calculator

Its the best one there is. Great UI. Love that it gives you extras. For example instead of giving you FeUrea of 18%. It reminds you that less than 35% is more likely pre-renal azotemia. They had something input wrong in a calculator, I emailed them and they responded within 15 minutes and fixed it in a day.
