Dividing doses before blood work.

Hi all, Thanks for all the support and guidance over the years! I would have been bedridden had it not been the good info I received since my thyroidectomy. I don’t post very often because I’m still not able to focus enough to write a proper post, but I read all the good info daily. I’m due for blood work in a couple of weeks and want to be fully prepared. I take Synthroid 62.5 + NDT 75, I’m looking for advice as to how to divide my doses the day before my labs. I take the full dose of both every morning at 7-8 am. Thanks to all who have helped me in this horrible journey!!

Last dose of Synthroid should be 24 hours before the test.

Last dose of NDT should be 8-12 hours before the test, splitting the dose and adjusting time if necessary the day before. You could split your NDT into 3 doses if it's possible, if not then 2 doses.
