When to get blood tests?

Hi knowledgeable people, I will have been on NDT for 1 month next week, having stopped 175mcg levo. My query is should I get bloods done at 4 weeks to see where I am? I am self medicating, private bloods. So far I am utterly crap but I understand these things take time, I also only started supplements at the same time as NDT so lots of changes. Only found out I have hashimoto's from private bloods a month ago, I just keep reading and learning and adjusting. Onward and upward but miserable while I try and get some control.

Skyebeardie Four weeks is too soon really. It takes six weeks for the levo to completely leave your body, so it's best to wait until six weeks is up.

Thanks seasidesusie, I wasn't sure.


Six weeks is best practice. Although with NDT some just keep raising the dose every few weeks till you reach about 3 grains and then start regular testing. With my own I am very cautious, though, and have tested for every raise - partly because a good doctor had told me I might require a very low dose.
