Sorry if this is a subject we keep returning to but I was a little confused by the recent discussion.
I need to arrange for phlebotomy services as I've decided to go the private route and will be having the full thyroid profile through Genova. When would the best time to have blood taken? When I was recently tested (at an NHS hospital) for TSH/T4 the bloods were drawn at 4.30pm and the results were:
TSH - 2.56 [range: 0.3-4.5]; T4 - 12.4 [range: 10-22])
Those who kindly responded when I messaged a few weeks ago stated that they thought my TSH was too high and T4 too low (but both obviously 'in range' as far as the medics are concerned). (Interestingly when I had TSH repeated, this time at 8.30am, the values were lower which I didn't expect.)
Given that I will be contacting an independent nurse/phlebotomist there may be some flexibility with regard to the time (within reason!!) to have the blood drawn.
Your help is greatly appreciated, as always.
