I'm having tests tomorrow for vitamin levels and thyroid function having been taking levothyroxine for two weeks. Just wonder if there is anything I should do or not do before the test? Should I take my levothyroxine pill in the morning as usual or not?
I realise 2 weeks is quite soon for a retest of thyroid function but I'm feeling peculiar on levothyroxine so want to stop if for a while to see if the strange symptoms stop. Dr advised a retest of thyroid function before I stop it.
