Besides the Schilling test, is there another tests which shows b12 absorption. My levels in standard testing are always really high.

I'm interested as well, tcoach - as the basic B12 - showed mine quite high...but apparently that doesn't show what we're absorbing...only what's floating around in the blood stream.

One of the best tests for B12 is an Active B12 test, which measures halotranscobalamin - this is the only form of B12 taken up and used by cells in the body. I'm not sure of the availability of this test in other countries though - I think it is still only available privately in the UK, not NHS.

I had a Genoa nutrival test done by Genoa. It showed me low on some b levels, including b12.

Quest also does histamine testing that reveals possible b12 problems
