Trying the micro-needle blood draw (my 1st experience w/ this)
It was a truly painless, efficient way to collect 100 ul of blood
Just push the green button; it took 2 minutes to get the red light to go on (= full sample)
According to the company @7sbio, the sample is sufficient for whole genome sequencing and 6-7 lab tests (not CBC or electrolytes). I have not seen any published data. This is one of at least 4 companies w/ micro- needle (so small you can't see them) blood draws.
Their 2018 paper @natBME provides the methodology, the data for HbA1c (@US_FDA approved) vs venous standard and projected price of $5.

[fulfilling transparency; peer-review standards] await data on other tests
My tweet from Feb '18 at time of @NatBME publication
Upgrading "painless" to painless.
