A member asked:

What are the impacts on tsh if you forget taking levothyroxine for 4-5 days before blood test? let's say it's 3,0 when on medication, would it elevate significantly?

Not much: I don't think 4-5 days would make a huge impact on your TSH, but it would be a good idea to let your doc know the situation just in case the values came back abnormal. Hope this helps!
