I am studying the limitations of Theranos device. They have 238 documents in Google Patents Search (Inassignee as Theranos), here. Which patents are relevant for their device? They have 70 tests which are not necessary to consider now. Just the basics of the device.
My intuition says that it uses PCR to multiply the microliter of blood for the analysis. What are limiations of multiplying so little blood? I think this is where their engineering work applies. What components do you need to multiply? I think all is not necessary. Otherwise, the specificity and accuracy can be difficult to hold.
How can Theranos blood test's be specific and accurate compared to conventional full blood test? I suspect if you can do the conventional full blood test with Theranos device with the same accuracy and specificity as the conventional one.
