Hi, can anybody tell me what it means if test shows high thyroglobulin antibodies please (72) . All others are well within range. Have been told I was borderline low t4 in past, but no treatment given. Had extensive thyroid bloods done privately, which showed high tgAB. I have symptoms of hypothyroidism including weight gain, significant hair loss, dry skin, tiredness, weakness etc. I also have palpitations which was also detectable via ecg and showed other abnormalities (being investigated at the moment) and have high cholesterol. Thank you.
