New study casts doubt on some fingerprick blood tests

To get 100 µl out you need more than a finger prick. Once you go this way you might as well cannulate. There might be some special cases where you can get 100 µl but not 3 mL, but this market is not going to support the weight of a unicorn.

Are you claiming that 5 drops of blood cannot be obtained via finger prick?

If he is, he's generally right. You get 1.5, maybe 3 drops out before it seals back up. Finger lancets are very tiny needles, even smaller than those used for insulin injections.

I worked in diabetes where finger stick tests are the lingua franca. 3 microliter sample sizes were common about 10 years ago for home use systems using relatively fine lancets. Using something just a bit larger would pretty easily get you 5 drops of blood.

Not out of one - well not easily or consistently.
