You're right, I guess there is the small matter of how much more than a drop is needed. If it's 3 drops, that's much better then 3 vials they they sometimes have to draw for covering a range of tests - but it sounds like it might be much larger then a few drops.

Even three drops is much more than one drop, if you're pricking my fingers a bunch of times, I'd rather you just did a traditional draw, it won't hurt when I type later.
