Hi, I need some help understanding my B12 results, my Doctor phoned me to say my B12 is elevated and to do another test on the 7 September, but I'm googling and it's frightening me.
But then I'm thinking if it was really bad I would be referred!
Thank you for your help in this matter.
Kind regards

Well, it is on that range, but ranges vary. Honestly, don't worry. Just stop taking it for a while and the level will come down. It's water-soluble, so you'll just pee out what your body doesn't need.
I get B12 injections every 2 months and when I last got a load of bloods taken mine was over 2000. The GP wasnt bothered although the lab did slap his wrist as its a pointless test when you're on injections. Its going to be very high, that's the point of the jabs.
So it looks as though supplementing has done a good job. Drop off the B12 now and just continue with B Complex, that should hopefully maintain a good level. You should have been taking a B Complex with the B12 to keep all the B vitamins balanced.
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg)
