Can I ask a question for the ladies regarding period and blood testing

[Tinkerbell_84]

Hi

After all the amazing information from this page I have booked an advanced thyroid blood yest iron and vitamins test. I've booked for next Wednesday the 17th but I'm due on my period any day now. Should I move my teat back another week or is this OK.

Thank you so much in advance x

I'm lost already 😕😂

Look at the two bottom graphs in Figure 1. They show how TSH varies considerably during the menstrual cycle. This raises two issues: -1. It's wrong to focus too much on TSH as in menstruating women it can fluctuate considerably.

2. Testing every six months is a bad idea as the teo tests will be at opposite stages of the cycle!

Thank you so much. I think every test I've done so far has been 1 week after my period. I also take co codamol for period pain coukd this effect test. Guessing it might.
