Hi everyone. Normally I would leave 24 hours between taking Levo and having a blood test. A few months ago however I started taking T3 also, and I have to split it half/half around 8am and again at 3pm, I would leave 12 hours before a blood test with T3. But at my last Endo visit I was prescribed a new brand (Prothyrid) which has both T3 and T4 combined, which has been great, but now I find myself not knowing how/when to take my dose before my next blood appointment which is next week.
I do still have some old T4 and T3 tabs that I could take separately, but the point is to see if this new brand is working for me and I don't want to do anything to skew my results.
I can take my blood any time from 8am to 12pm on the day of my test. Should I just take my meds as usual and do the test right at 8am? That would leave 17 hours from my last dose.
Any advice would be appreciated.
