Short Synathcen test

[heathermr]

I am having a short synathcen test on Monday at 9am as it looks like I am going into pituitary failure. Should I take my T3 medication (I am T3 only) before having the test or wait until after? They are not looking at any thyroid values as they already know that my TSH does not work- ie is permanently zero.

Heathermr,

Probably best to contact the hospital and ask whether you need to leave off taking thyroid meds before your SST.
