I believe the latest blood tests he ordered have something to do with testing for that gene. It's hard to tell. He narrowed it down to the four possibilities and told me that the best options for treatment for any of them is Humira or Methotrexate. I know I need to go in for a TB test before trying any of the meds and I need to see what my insurance says.
I don't know if the discovery of others in my family receiving an AS diagnosis will help. I just hope my father takes the time to have himself checked out. He's been using OPC supplements for several years and says they have helped him.
