Guidance Needed for Thyroid meds dosage on Armour Thyroid & Additional T3, prior to blood tests

[FunkyC]

Good morning,

Id really appreciate some guidance of dosing prior to my thyroid blood test please. I am dyslexic and find processes quite tricky so please bare with me.

I’m on Armour Thyroid 2.5 grains (NDT) & additional 15mcg T3 combination

Im a bit confused with meds taking prior to blood testing.

I understand I need to take my last T3 dose around 12 hours prior for the T3 reading.

My Armour Thyroid reads on the label for 1 x grain (60mg)

Levothyroxine 38mcg

Liothyronine 9mcg

I’ve read that if you take Levothyroxine that the last dose should be taken 24 hours prior so would this be the same for me with my NDT containing Levothyroxine ?

I usually spilt my dosage of both medications between Morning (7am) & Lunch (1pm ) and aim to take the test in a morning at approx 8am.

Many thanks in advance
