    Hi all hope you all well has can be. Some think been on my mind and you guys might be able to solve it.

     

    when I had my pet scan end of June my 3 month bloods was due at my GP at the end of July. On that test my thyroid was lower which my GP said we will keep watching it in 3 months time on next bloods. Unfortunately I had 2 nodes in chest positive so started keydruda. On bloods test my thyroid had reduce to 0.4 which was discussed in clinic on visit. They asked me how I was feeling as this was low and would start treatment if had symtoms. 

    I replied this is what I am dealing with at present. The Mel, going through menapause, sinus issues and now low thyroid. I suppose lots of side effects I am feeling could relate to most of my issues. They have decided to wait 3 weeks for next bloods. 

     

    What point if you had a thyroid issue went on treatment and can pets an interfere with thyroid results.

      Hi,

      I don't know if pet scans interfere with the blood test results.  I only know when my thyroid numbers were off they put me on medication right away.  No waiting.

      Good wishes to you.

      Not sure if this helps, but my experience is that my Endocrinologist always wanted me to wait until at least 2 weeks after any CT or PET scans for any of the contrast injections/agents to flush out of my system before retesting blood levels to check my thyroid.

      I looked at my labwork after reading this.  I was put on 25mg of synthroid after 2nd treatment, then 50mg and am now on 75mg.  My last Petscan was on 9/11 and i don't see where it changed any of the numbers. Due to my high lliver panel and being still on Prednisone my blood is tested either once or twice a week depending on the ALT/AST numbers.      Scroll down to see                                                                                                     Name TSH

      9/18/17      26.47 (7 days after Petscan )
