A true theranos machine

Big and bulky but actually works and is available at every drugstore and doctor's office

Well not that big, but not the rediculously small size that they falsly presented.

Is it really impossible to do the 50 or so usual tests with only a single drop of blood?

       What's the difference between Thanos and Theranos?   

       One makes half your wealth disappear, the other, all of it.

       With your current wet-biochemistry technologies, yes.   

       In the future, no - likely to be practical, and indeed many diagnoses and measurements may become non-invasive, using saliva or other ... bodily fluids.

       [marked-for-deletion] Wasn't that cool, that thing at the center of the well-known large-scale fraud?   

       If you have disposable income and like to listen to, or read, true crime books -- I very much enjoyed "Bad Blood" (the 2018 book, not the Taylor Swift song) by the (then-) Wall Street Journal reporter John Carreyrou, who was one of the first calling bullshit on the company and deeply reported on it across the arc of its existence. It goes a little bit into technical details of why getting microsampling right is so hard, based on interviews with technicians who were trying to make the "inventions" work behind the scenes. (I have no opinion on the Taylor Swift song.)

       Patterns of spotlight EM reflections, transmissions and absorption ? Ultimately, doesn't everything sing differently in it's own unique way ?

       In an answer to the question Could Theranos have ever worked, by a blood testing expert with 40 years of experience:   

       Yes. Most biochemistry tests now only need a few microlitres of blood. But you need to allow for repeat testing and some tests need different anticoagulants.   

       And there's a 2017 invention that may allow this to be applicable, see link.   

       And then there is rHealth. See link   

       When Holms was a student she was told by Professor Phyllis Gardener that "when a finger is pricked, the probe breaks up cells, allowing debris, among other things, to escape into the interstitial fluid. While it is feasible to test for pathogens this way, a pinprick is too unreliable for obtaining more nuanced readings. Furthermore, there isn’t that much reliable data that you can reap from such a small amount of blood."

       If the universe is a hologram then the smallest part has all information.   

       More likely, in reality, a tiny sample has to contain a key giving the answer to the question, or an answer inferred from a set of keys.   

       Too tiny a sample and the set of keys just won't be there.
