I see dozens of conditions this would be good for. I think you get biased once you spend 8-10 years becoming a gatekeeper to healthcare.

People want to take their health into their own hands and not have to have every test blessed by a $150 doctor visit plus a separate lab visit.

Conditions to test for:

Hemachromatosis Many other genetic conditions Vitamin deficiencies (D, B, potassium) Blood sugar for people prone to diabetes Lyme disease (test after every tick bite after waiting the required time period)

And that's just off the top of my head.

Many of those are tests I'd like to a few times a year, but don't want to schedule a doctor appointment, take off work, make a copay, schedule a lab test, take more time off, another copay, etc.
