I have no intention of being snarky here, but perhaps someone can break it down to a layman how this might differ from Theranos' approach?

In almost every way, aside from the use of "a drop of blood"?

Snark aside, this article is claiming testing for a single blood parameter, clotting time, using purpose built hardware / software methods, vs the Theranos claim of building a single lab-in-a-box type device, that could test for myriad conditions or parameters all via a single drop of blood.

Measuring clotting time with a single drop of blood isn’t new. This is already done in doctors offices.

Doing it with a smartphone is new. I don’t think Theranos ever claimed their tech could work on just a smartphone.

So this claim is really, really different from Theranos.

This is one of the worst aspects of frauds like Theranos. They poison the well for others attempting to address what are genuine problems.

Some tests work fine in a single drop of blood. Some need more volume to pick up the very tiny concentrations of what you are trying to detect, particularly antibodies or antigens.

If you're trying to find a needle in a haystack you can't grab a handful, look at it, and say "nope, no needle in this stack!"
