Hello owtbac86 and All,
Thanks for the info;
Here is a video from Clearidium regarding the current collection process:

and looking at 'one drop' testing in the not too distant future:
https://motherboard.vice.com/...on-one-drop-of-blood
Patterson said that, currently, each sensor costs the company about $10 to manufacture, and that at scale, that cost could drop to pennies. He added that the big obstacle isn't manufacturing, but showing that the sensors can produce accurate enough results to be reliably used in medical applications. [emphasis added]
"The challenge with a lot of these sensors is not always sensitivity, because there are a lot of things out there that are very sensitive," he said. "It's the selectivity, making sure we don't get a false positive."
"But while medical diagnostics are an immediate, obvious use of the tech—and seriously, who wouldn't want to test themselves for a couple dozen medical issues in minutes?—the sensors also have potential for use as environmental monitors. By attaching custom-built DNA strands to their sensors, Patterson said the company can scan for a variety of volatile organic compounds."
"In the promo video above, for example, the company suggests its sensors could ​mimic the noses of drug- and bomb-sniffing dogs, monitoring for contraband in a persistent, ambient fashion. Imagine filling an airport with low-powered sensors that automatically sound the alert when cocaine molecules float by. The TSA would buy them in a heartbeat."

'One drop' collection problems and possible solutions (besides leeches, ticks, mosquitoes, fleas, bedbugs, and the the like.)
"Meanwhile Howard J. Weisman, CEO of Seventh Sense Biosystems, hopes to sidestep finger sticks entirely with a new method for removing blood from capillaries. The company’s golf-ball-sized Tap device pricks the skin, usually on the upper arm, with an array of microneedles and then vacuums out the equivalent of two drops of blood through the resulting micropunctures. “People say it feels like someone tugging,” Weisman says. No bandage is required, because the pores are so small, although pinprick marks do show up a bit later."
“What we end up with is a very high-quality capillary sample,” of the same quality as venous blood, Weisman says. Because it pulls the blood out from capillaries just under the skin, he says, there is less tissue damage and no milking of interstitial fluid. The company expects FDA approval soon and plans to commercialize the devices in 2017. The company is talking with instrument-development companies to possibly combine its Tap collection method with small-volume analytical devices, many of which are coming to market able to do multiple assays on just one to two drops of whole blood, Weisman says.
“The idea of testing in a pharmacy is not going away. That’s an area, we think, that is ready for significant growth.” [emphasis added]
