Jimmy,
It's funny you should mention the accuracy of the test.
When they gave my wife the results from my son's test, they said "he has a 70% chance of not having it".....I obviously wasn't happy in hearing that and questioned this "70%" thing to my wife as I was not present during her visit. I guess I owe her an apology.
That
is disappointing though, one would think they can confirm Yes or No......not maybe.
