I have suspected that I have an underactive thyroid for some time but all tests by the doctor have been normal. In Nov 2016 I had a private test by Medichecks that showed I had a high thyroglobulin count. Just after this I was diagnosed with a tumour in my chest and told that something was wrong with my neck. I showed them the Medicheck results but the other stuff was obviously more important to them. Tumour (non cancerous) was removed from chest in Feb 2017 and eventually they removed a diseased parathyroid adenoma in Feb 2018 which weighed 1.1gm - a thousand times bigger than it should have been. At my follow up, I told them again about the high antibodies and asked if it could be Hashimoto's and the endocrine specialist said yes, but she didn't suggest another test so I had one done by Medichecks. The result is below. I would be really glad of some advice.
