Diane, I also had a bone marrow biopsy done because of low platelets. I was diagnosed with ITP, another auto-immune disease. It seems to be more common in people with graves. People who are HYPER with Graves’ also can have low platelet counts because of the hyperthyroidism, which will return to normal when thyroid levels are normal. I hope that’s all your problem is. Let me know–perhaps we have more in common than our names!
