Repeat blood test advice?

[Pinebunny]

I think I have been under-medicated for some time. My GP agreed for me to try an increase in Levothyroxine and has left a request for repeat blood tests to pick up when I am ready.

Can anyone advise how long after an increase you can assess how you feel and also when to re-check T3 and T4? I am taking regular photos and after one week I can see my face looks less puffy which is encouraging!

Thank you, but wanted to know when I should do the repeat test?

don't forget to do the blood test first thing in the morning and don't take your thyroxine for 24 hours before the test. Take it afterwards instead.
