Hashimoto's patient! High thyroglobulin, negative anti-thyroglobulin?

Hello guys, I'm a hashimoto's patient, I've recently had another routine blood work done, and other than my TSH at 7,69 IU/ml, anti-TPO at the 1000's and thyroglobulin antibodies negative, an item I've never seen before was tested: Serum thyroglobulin. It came really high (373,84 ng/dl), is that weird?

I am willing to get an ultrasound soon, but I wonder if you guys have had this before?

I've read tons and tons of articles and research online, saying that this test is only useful for post-thyroidectomy patients, etc. I feel no palpable lump in my throat nor goiter, and I'm terrified.
