Diagnosis is supported based on vitamin B 12 blood levels below 150–180 pmol/L (200–250 pg/mL) in adults. [51] However, serum values can be maintained while tissue B 12 stores are becoming depleted. Therefore, serum B 12 values above the cut-off point of deficiency do not necessarily confirm adequate B 12 status. [2]
Serum vitamin B 12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins.

Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
