Should I do Thyriod Medicheck test while on Antibiotics

[ssjg]

Hi, Happy New Year all

Quick question, I’ve had a chest infection for the last two weeks and am nearing the end of my antibiotic course (Amoxicillin).

I’d intended to do my Medicheck test tomorrow morning (before Levothyroxine) as it’s 8 weeks since my dose was put upto 100mg.

Would I be wise to wait until the course is finished and I feel brighter, could it affect the results?

I would say wait till you are better, you should not do bloods while you are poorly, I am not sure about the antibiotics affecting results but any infection should be over, or you will need to do a retest.

Some people advice waiting 12 weeks after a dose change so this may be better all round for you hopefully you will be well over the infection in another 4 weeks,

Any acute infection can affect your thyroid results, it is recommended to wait until a few weeks after the infection has cleared before doing a thyroid test otherwise you cannot rely on the results being accurate.

Thank you, I’ll wait a couple of weeks as suggested.

I would wait a couple more weeks at least if you have had an infection or have been unwell with a cold or Virus. When looking at when my routine blood tests were taken pre COVID pandemic, they always coincided with a GP visit or a few days after for either an infection or generally being unwell, nearly every time it resulted in a dose change up or down. I would see the GP and whilst there they would say you haven't had a TSH check lately and that would be it.
