One Less Needle

When I gave blood twenty years ago the worst part, by far, was having the tip of a finger stabbed by a needle.  They would take a few drops and drop them in a mysterious liquid which made sure my hemoglobin was high enough to allow me to give blood.  Roll time forward to 2020 and that finger stick was amazingly painless.  They still got their drops and I still got a bandaid, but it was a great improvement.  

All that has gone by the wayside this year with the introduction of the OrSense NBM200, the machine shown below.  You just put your finger in the ring‐shaped sensor probe and a minute later it displays its results.  All that's left is the sting of the vein-tapping needle, but who knows, maybe they'll find a way to eliminate that and make Dr. McCoy proud.
