Though precision dosing is being promoted and has terrific promise, it is actually underutilized in many drugs and illness states. Thus, we think it's important to look at how much more specific dosing will probably be shipped to higher precedence clients within a well timed manner. If superior dosing strategies do not modify clinical follow causing far better client results, then what may be the use?
