So 3 months ago my B1 came back low. It was a 6 I believe. So doc said to start taking 500mg a day. wasn't the best student, and probably have managed to get that 500mg 3-4 days a week since.

I got back my B1 results from last week. Now my number was a 66??!! Crazy high according to the 'normal' range that DLO had posted. It also had a disclaimer that taking it up to 24 hours prior to test could result in a false reading.

First, no one told me not to take out the day before.... But if did take it, it was before 4pm the day before (I take it at work).

Wtf?! Any ideas? I'm going to call my doc on Monday, but I'm perplexed.....

I'm apparently an overachiever I guess?

It could be you just took it too soon before the labs were drawn. I've seen various medical opinions on it, and different vitamins have different wait times. But I would stay off all supplements for at least 3 days prior to labs.

I'm sure there is B1 in your multis as well. Maybe you just had enough?

I would ask for new labs, and stay off the multi for a few days prior.

Thanks. I'm going to definitely ask for a new full lab draw, and not take anything for a few days...

If hate to think I've got 'normal' readings on something else that is actually low, ya know?

I'm sure I put my patches on that morning too... I guess I missed the chapter on not taking supplements before a blood draw... Duh.
