Serum vitamin B 12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins. [1] Most of the time, 80–94% of vitamin B 12 in the blood binds to haptocorrin , while only 6–20% is binds to transcobalamin ll. [ 2 ] Only transcobalamin ll is "active" and can be used by the body.

Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
Diagnosing Vitamin B12 Deficiency and Cancer [38] If cancer is suspected as the cause of vitamin B12 deficiency, several diagnostic steps are necessary: Blood Tests : A simple blood test can measure vitamin B12 levels, along with other markers such as homocysteine and methylmalonic acid, which may also indicate a deficiency.
TC-2 binds cobalamin once it has been taken up by enterocytes of the terminal ileum and the "Intrinsic Factor-Vitamin B12" complex has been degraded. TC-2 is then involved with the transport of Vitamin B12 to the tissues, where it binds to its plasma membrane receptor (TC-2R), a heavily glycosylated protein with a monomeric molecular mass of 62 ...
Upon binding cobalamin, important elements of the binding site appear to become structured, including an alpha-helix that forms on one side of the cleft accommodating the nucleotide 'tail' of the cofactor. In cobalamin, the cobalt atom can be either free (dmb-off) or bound to dimethylbenzimidazole (dmb-on) according to the pH
Intrinsic factor (IF), cobalamin binding intrinsic factor, [5] also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells (in humans) or chief cells (in rodents) of the stomach. It is necessary for the absorption of vitamin B 12 later on in the distal ileum of the small intestine. [6]
A Chem-7 is thus a vital tool when attempting to stabilize a patient. [citation needed] Calcium (Ca 2+) is often considered part of the BMP, [9] [10] though, by definition, it is not part of the CHEM-7. A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8".
The comprehensive metabolic panel, or chemical screen (CMP; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, diabetic and parathyroid status, and electrolyte and fluid balance , but this type of screening has its limitations.
