What we test
This test measures your total vitamin B12 levels in the blood. Vitamin B12, also known as cobalamin, is essential for numerous vital functions in your body.
Red Blood Cell Formation: B12 is crucial for producing healthy red blood cells. Deficiency leads to megaloblastic anaemia, where red blood cells are larger than normal but fewer in number, reducing oxygen transport throughout your body.
Nerve Function: B12 maintains the protective covering (myelin sheath) around nerve fibers. Deficiency can cause nerve damage, leading to numbness, tingling, balance problems, and cognitive issues.
DNA Synthesis: B12 is required for proper DNA synthesis and cell division. This is particularly important for rapidly dividing cells like those in bone marrow that produce blood cells.
Energy Metabolism: B12 works with folate to convert homocysteine to methionine, supporting energy production and reducing cardiovascular risk.
