I'm wondering which blood test to have done to test my thyroid function.
I've had fatigue / anxiety/ poor sleeping / problems trying to put on weight or muscle (i'm very tall and slim) , constant sore throats, cold hands and feet for most of my adult life. (on and off). Recently it got worse, coupled with very low libido / some erectile dysfunction and brain fog and memory problems. MY GP ordered blood tests including testosterone, all of which came back "normal". The response was "come back in 6 months".
I then ordered my own, more exhaustive testosterone test from Medichecks which gave a high SHBG level (out of range) and a low free androgen index (right at the bottom of range). The notes accompanying the test suggested I get a thyroid check done. I've since read that high can SHBG / low free androgen can be a sign of Hyperthyroidism. (The GP only did a simple TSH test)
I'm just not sure which one to get.
There's this one:
or this one
or this one
(which I quite like as I can get a nurse to come round I gather and do the sample (I'm not terribly good with the finger prick tests).
I feel I have more of the symptoms of hypothyroidism than hyper except that I have a tendency to lose weight rather than gain it....although I gain fat round my belly very easily.
Happy to provide more info if needed.
