My wife and I took the AB test yesterday here in SoCal. We opted for the blood draw, Quest test instead of the quick, prick test.Encouraging data still continues to come in.

Two respected medical professionals here have expressed reassuring opinions, but I’m not sold on the testing reliability just yet.
