Ichor definitely IN, doubt the Rexall story...I don't believe that the StageZero test will be available over-the-counter.
Two reasons:
They never got FDA approval.
Who (besides diabetics, who are taught how to jab themselves by the
medical practitioner) does a blood test "over-the-counter"?
That being said, ICHOR is definitely in, and StageZero is already their diagnostic tool of choice...

So, GLTA!
