Blood Test

I took my bloods to send to Medichecks this morning at 6.30, but had already taken my Thyroxine at 6.05, do you think the Levo would have taken effect that quick.

I only ask, as it seems widely talked about doing bloods before Thyroxine.

Den53, I doubt the Levothyroxine will have been absorbed in 25 minutes. It will usually peak in the blood 1-2 hours after ingestion. In future take Levothyroxine after a blood draw.

Blood tests only measure what's in your blood not whether its working. If you take meds within 24 hours then results will be skewed.
