Wonders? Really? When the idea for the saliva test was submitted to him by a homeless man who is known for digging in NY City sidewalk cracks to find tiny specs of gold? (not one bit of exaggeration there).
The scientists that told him the blood tests wouldn't work didn't suggest it, but instead a homeless man suggested it, and there is need to wonder?
I'm going to go out on a limb here and suggest the saliva test is "just as effective" as their blood test!
"But one wonders if the saliva based test kit is also a wishful thought only "
