Laboratory assessment of vitamin B12 status

No single laboratory marker is suitable for the assessment of B12 status in all patients, so Sequential assay selection algorithms or the combination of multiple markers into a single diagnostic indicator are both approaches that can be used to mitigate inherent limitations of each marker when used independently.

The Application of Holotranscobalamin and Methylmalonic Acid in Hospital Patients and Total Vitamin B 12 in Primary Care Patients to Assess Low Vitamin B 12 Status

The prevalence of low B12 status in internal patients was higher than for external patients and the incidence of elevated MMA in the small group of external patients was high; suggesting that the application of total B12 alone may not identify all patients with low vitamin B 12 status, and that MMA is a useful marker in confirming B12 Status.

High prevalence of vitamin B-12 insufficiency in patients with Crohn's disease.

BACKGROUND AND OBJECTIVES In Crohn's disease (CD), belonging to inflammatory bowel disease, the small intestine is involved in most cases. Most frequently affected is the distal ileum, where vitamin

Significant Reduction of Vitamin B12 Levels in Sudanese Sickle Cell Disease Patients

The mean of serum Cobalamin in the sickle cell patients was statistically significantly lower compared with the normal non-sickle cell disease group with p value = 0.01; 7.1% of Sudanese Sickle-cell disease has a deficient serumCobalamin (hypocobalaminemia).

The importance of supplementing vitamin B12 (methylcobalamin, vitamin B9 (folic 24 acid), vitamin B6 (pyridoxine), and SAM to patients in early stages of LOAD is emphasized.


To prevent irreversible complications, early diagnosis and adequate supplementation of vitamin B12 deficiency is essential, best done by detecting the subjects at risk (AG patients) by targeted GastroPanel screening, even years before the development of protean clinical manifestations.

Evaluation of vitamin status in patients with pulmonary tuberculosis.

Severe neuropsychiatric symptoms due to vitamin b12 deficiency: a case of pernicious anemia or metformin use?

A case of a 49-year-old adult patient with type 2 diabetes medicated with 850 mg of metformin per day, which presented a clinical scenario of severe vitamin B12 deficiency with associated pancytopenia, postero-lateral demyelinization of spinal cord and acute psychosis, which recovered completely from the neuropsychiatric and hematological dysfunctions with parenteric vitamin B 12 treatment.

Vitamin B 12 deficiency : metabolic effects , clinical evaluation , and treatment

The physiology of vitamin B12 from its digestion and absorption to its distribution in tissues, metabolic effects and controversies regarding the diagnosis of deficiency, and to dietary and pharmacological treatments are reviewed.

Vitamin B 12 in relation to oxidative stress : A 2 systematic review 3

The evidence appears to suggest that lower B12 status is related to increased pro-oxidant and decreased antioxidant status, both overall and for subclinically deficient compared to normal serum B12, but randomised controlled trials and prospective studies focusing specifically on the relation between B12 and oxidative stress in humans are lacking.



Anaphylactic reaction after injection of vitamin B12.

The patient had no history of allergic diseases, and had not previously shown allergic or adverse reactions to drugs, but within a couple of minutes after receiving the last injection of hydroxocobalamin he developed symptoms of anaphylactic shock, with peripheral circulatory collapse, unrest, shivering, and general itching.

Sensitivity to cyanocobalamin and hydroxocobalamin.

Attention is drawn to sensitivity to cyanocobalamin and hydroxocobalamine as a cause of chronic urticaria and to report the case of a patient who also reacted to vitamin B,2 given by mouth and the findings were noted by H0vding (1968) in his report of a case of anaphylaxis after intramuscular injection of vitamin B.

Erythrokinetics in pernicious anemia.

Quantitative measurements of the erythropoietic activity of the marrow, of circulating red cell production and destruction have been made in patients with pernicious anemia in relapse and during response to vitamin B12 therapy, indicating that the greater portion of marrow activity is ineffective in terms of blood production.
