Does anyone know if a TSH level of 8.56 will preclude me from having a GA tomorrow. I am scheduled to have a vulvoscopy in the morning but my TSH has come back a bit high. I'm fit and healthy otherwise and on thyroxine, so I'm under control. Problem is I am now waiting for the 'go ahead' from the anaesthetist. So frustrating. Have arranged cover at work, husband has taken time off, kids booked in at childminders etc. Aargh!
