Stephen, I had genetic testing done 5 years ago by a cardiologist for something else so it wasn't a full gene testing. That's how we found the MTHFR genetic mutation. He didn't even mention it to me. I always request a copy of my lab reports and go over them. That's how I found out and took it in took my PCP and discussed it with her. She explained it a little bit was clueless as what to do. A mixing pharmacologist that I just happened to strike up a conversation with has it, so he explained more and that I needed to take supplements. I started researching then.
