Preface: I am a med tech and have managed a lab. This looks like bullshit. She's invented a marketing campaign for her lab. Her 'nano-tube' is the exact same thing that already exists, called a 'microtainer' made by BD. These get used in hospitals right now every day. Finger pricks also get done daily, usually on kids.
Finger pricks are undesirable samples for the following reasons:
1) Manual manipulation ('milking') the blood out of the finger results in higher chances of hemolysis - which can render the results of many tests invalid.
2) Finger pricks have a higher volume of interstitial fluid in the sample, possibly skewing the results
3) Finger pricks take longer
4) Finger pricks actually hurt more than a needle
5) Finger pricks tend to clot in the tube, a big no-no for CBCs. Modern chemistry and hematology analyzers only use microlitre amounts of serum per test. Every day labs do full chemistry panels on microtainers of blood - so I'm not sure why her system is better.
Now cost.
I'm sure that in the US testing costs a lot more than in Canada (dat profit) but in my lab the cost of reagents to do a standard panel (electolytes (Na, K, Cl), glucose, kidney function (BUN, Creatinine), liver function (ALP, AST, ALT, Total Bilirubin), automated CBC) would be on the order of $4-6 (and this is in a fairly low volume lab). If a stat sample is delivered to me I can have results back in 15-20 minutes on any modern chemistry analyzer for the above mentioned tests.
The reasons we take tubes with 'large' amounts of blood (I put 'large' in quotes because each tube holds about a teaspoon of blood, I could literally take 100s of them out before you'd feel the effects of blood loss) are:
1) It's a better sample - less recollections
2) We have extra in case there is a problem in analysis - less recollections
3) The Dr. can add on more tests if something comes back weird - less recollections
4) The Dr. can order immunoassays or esoteric testing that requires more volume - less recollections
Are you seeing a pattern here? The lab does NOT want to be recollecting. It's a waste of your time and a waste of our time. Why not take extra that you're not going to miss in the first place instead of having to come back a second time? Unless she has some breakthrough testing methodologies that require significantly less blood than is currently used. And I don't think some Stanford dropout working in her garage is better able to develop these tests than multibillion dollar diagnostics companies.
Trust me, if some company came along with an analyzer that required 10x less sample with no downsides, they would win the entire market and sell billions of dollars of reagents. Of course they'd be doing it if they could. She goes on about 'automated analysis' in her interview a bit, but labs are already HIGHLY automated. The trouble comes from shitty collections (fingerpricks) and shitty delivery times. She mentioned the problems of people not coming to get their bloodwork done because scared of needles - this is a problem, but its a pre-analytic problem that is not going to be solved with a new micro sampling technique. Bullshit.
