As killercarrot wrote, this app is a little light on some of the details and has a few errors. The user interface and concept of the app are excellent however! I also think MedRef is great for normal lab values to use in conjunction with this app.

Now I don't have to try to remember all this stuff off the top of my head... Lyte to add: magnesium (not that common a problem but still something to consider, esp with the K already there)...

Looks good, but VERY lite on info

For the price, this app is very much a disapointment. Not much more than a list of normal lab values. In the case of hyponatremia, suggested tretment do not reflect Verbalis guidelines (where are the vaptans?). It could be a very good app if expaneded with TX detail. . At this point save your money go with a cheaper simple lab value app like MesRef
