High thyroperoxidase AB - miscarriage?

After suffering a missed miscarriage at 13 weeks with my first IVF pregnancy, my RE did a RPL blood work panel.

My thyroperoxidase antibody came back very high, nearly 1000 (normal is 0-60), but my TSH is normal. I’m wondering if anyone else has this problem and went on to have a healthy pregnancy? What was the recommendation by the doctors? I am still waiting to go over my results with my doctor, but the waiting is making me insane!
