I had to take a pre-employment drug screen today.

Customer Question

Hello, I had to take a pre-employment drug screen today. Periodically, I take B-12 supplements (3000 mcg). I am now reading information that this supplement can trigger a false positive. How much has to be in the system for that to happen and should I be concerned?

you shouldn't be stressed

b vitamins should not cause false positive for your employment screening urine tests.

B vitamins are very common, and is supplemented in your foods, breads, cereals.

b vitamin deficiency is very very uncommon because of so much B vitamins supplemented in our food sources

you don't have to worry about it causing you false positive urine screenign
