Ladylove and boatman, you are on the right track.....the Q-RIBb test from Bowen is no longer available; the new Flow Cytometry test, which is based on the same priciples as the Bowen test, is now available through Central Florida Research Labs.
Be sure to call them, though, if you are considering this test.... I heard recently that there is a snag in the 'approval process' of the Flow Cytometry test so I'm not 100% positive that they are able to do any testing at the moment!!
