I think your levels are terrific! But, what do I know. My doctor always wants to see my levels at 40. But, from everything I've read, a level over 10 is suppose to be sufficient.
Each doctor is so different in what they want/expect. The other thing to remember is that each lab is different in how they read things so it could just be that.
All that being said, it never hurts to have a lot of P4 on board. You might have a few more symptoms but it isn't going to harm you.
