Definition The vitamin B12 level is a test to tell how much vitamin B12 is in your blood. How the test is performed Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic).

The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding. How to prepare for the test Yo...

But don’t panic and throw-out your antireflux drugs without investigating further.
They’re using a type of statistics that can magnify a small effect. For example, let’s say the risk of something in your age group is 2%. You have a 65% increased risk. That means your risk is 3.3%. Greater, yes, but still relatively low.
Metformin can also contribute to vitamin B 12 deficiency. This has been known since before I was diagnosed in 1996. In fact, the effect of the PPIs on B 12 deficiency has also been known for some time, as mentioned i...
