Blood test help

[janey1968]

I had bloods done on April 2nd and there is still no sign of the results for thyroglobulin, I know they take longer but it has been 8 weeks , I have the forms to have TG tested again but just wanted to know do I take my meds or not? im currently taking 125mcg levo an 20mcg lio and I know these can affect the result of bloods if testing for T4 T3 tsh but does the same go for thyroglobulin only?

Janey, My Tg is usually tested along with TSH, FT4 and FT3 so, I'm not sure. I'd play safe and take meds after the blood draw.

Thanks clutter, they were all done together but the TG seems to have gone astray and they are requesting it again
