Agreed. I was expecting something revolutionary in the report linked from the article. I'm pretty shocked that a technique from the 1970's is only now "disrupting" the medical laboratory industry. I'm not saying that this isn't impressive, just that it seems it should have been done a long time ago!

For those of us that are more conversant in microservice golang APIs... explain?

It's the kind of biochemical assay that pregnancy tests use, so not exactly cutting edge. https://en.wikipedia.org/wiki/ELISA#Sandwich_ELISA

Furthermore, certain types of ELISA have been in use in clinics and hospitals for many years ... but they have always required venous sticks and a lot more blood. ELISA has also historically been expensive due to the amount of antibody required--the microfluidics approach is much cheaper in this regard.

Microfluidic device open lots of possibilities in health care(and might bring some of the dynamics of moore's law and the computer industry to health care). Although not new, they are rarely used for routine blood tests.

So anybody who bring to healthcare, especially at this price point, and at this comfort and offering the ability to order your own tests, holds lots of potential.
