I've had a few health concerns recently that could be attributed to thyroid issues (or could be something else entirely of course). I had bloods done a couple of months ago and asked for a copy of results today. It reads my free T4 as 19.5 (high end of normal range??) and my tsh as 0.77 (low end of normal range?). Does this mean anything to anyone as Google is bamboozling me. I am aware the NHS 'normal range' causes some controversy which is why I ask. Thanks so much for any advice
