Is this considered more of a diagnostic test? I really do not see the need for the patient to be able to test for this at home. It provides them with no pertinent information. If anything I would think it would make them believe there is less of a need to visit their doctor because of it.
When I first saw it I thought it was simply a capitalistic endeavor by Bayer, but I'll defer to those who are more knowledgeable on whether or not this serves a legitimate purpose.
