Once a day T3ers only

Do you still do your blood tests in the same way as those on divided doses or T4?

I can't think of any better way unless someone has any ideas?

I am taking all my T3 on waking so got earliest appointment I could ( testing other stuff too so can't do my own finger prick test) and that is 10am Mon, sadly none earlier. So I have moved my t3 towards 10am for the last couple of days.

It will give a baseline level like with other types of thyroid testing, but is just further from last dose than when I was splitting the dose.

I now split my dose into 3 before testing, leaving 12 hours from the last dose.So the last test i was on 75mcg.

Took 35mcg morning, 20mcg afternoon and 20mcg at 8.30 pm. Blood drawn 8.30am.

My ft3 result was 6.2 (3.5-6.5) blood were for my endo appointment

He knows i take one dose and i split it before testing. He wants me on split dose but can't split as try every year for the last 10 years and feel I'm taking nothing by day 4

Although I take my T3 in one dose daily, I split it into two the day before my blood test trying to get as near to 12 hours before the test time for my last T3 dose.
