Hey
I've just posted on this issue, but didn't know til gynae told me that if you've applied gel to the arm that you used for the draw in the previous month it can corrupt the test, ditto the hand of the arm for the test. So I use my left arm for bloods, so been applying gel with my right hand to thighs and with the lid of oestrogel pump pack to my right arm to avoid using my left hand.
I'm still unclear on how testing off gel (given it's nearly out of our systems within 24 hours) tells us anything though - I did one test off, and then another a month later with gel applied (not the arm) two hours before testing.
It frustrates me that there's no clear guidance on this, as it seems a fairly important fundamental question for women on HRT - is it absorbing or not?? I get that there will be tissue levels, which is why they say leave at least a month between any dose change, ideally three, as it gives time for the body to calibrate but quite why gynaecology hasn't yet come up with a bloomin' factsheet on this, no idea, would save us all a load of time, worry, and money.
Gynae wants my levels 600+
