The results of this effort indicate the following:
Sensitivity - 100%
Specificity - 94%
Positive Predictive Value - 95%
Negative Predictive Value - 100%
Non-invasive studies that correlate with the gold standard 90% or more of the time are very good. Certainly these statistics compare very favorably with those of high quality non-invasive vascular laboratories across the country.
How did you find these people?
I'm not sure whether this is a binary test, or whether there is some value judgement made about the degree of disease, but this certainly seems to be the best, most cost effective option. Although I am now sure what "3 tests" means, if it means 3 tests is over time, then we might be able to evaluate a subject for less than $200 using this method including blood work.
Lets figure on 20 people. $4,000.
Vitamin C and lysine for 20 people for 1 month $100 * 20, or $2,000
So for $6,000 to $10,000 we can study 20 people.
For $3,000 to $5,000 we can study 10 people.
After I learn what you know about this service, I may try to contact them and see how we might enroll people and monitor results.
