Blood Test For Thyroid Issues - Can I Drink?

[S_Austin]

Hi,

This more than likely is the wrong forum, but I could not find a more suitable one.

On Friday I am having a blood test to determine whether I have a thyroid disorder, I am just wondering what the situation is on drinking alcohol the night before a blood test. I would presume it would not be recommended as it would thin and contaminate the blood, correct?

Yes it it might depend on what meds your on as well, im only on T4 med.

I've always been told that taking thyroid med prior to testing can skew the tests, especially if you are on a T3 med, such as cytomel, (I am) because it works very fast and my levels might be higher if I've taken my med than they would otherwise.  I don't go to a hospital for my tests.  I get a lab order from my doctor and go to a lab.  Both the lab and my doctor have given these instructions, so that's what I do.

I have never had to fast for a thyroid test (dealing with it for 15yrs now), but I guess every hospital is different. I have never even been told NOT to take my medication before getting lab work for thyroid levels.

Now this is interesting..I have only heard fast for my Cholesterol 12 hours only water..Nothing bout Fasting for thyroid blood test, does it make a difference to the test?  I Haven't heard dont drink before a test, but i probably wouldn't..

I've always been told to fast for 8 hours prior to my thyroid tests and nothing has ever been said about alcohol, but I usually don't drink the night before.  I've also been told not take meds prior to blood work.

Hi,

Thyroid tests don't require fasting.

Recommended  not to drink alcohol the night before though.

Lipid profile and fasting blood glucose do.

Best wishes

You should fast 14 hours before the test and drink a lot of water !
