While you can get vitamin B12 from food sources like meat, eggs, and dairy, deficiencies are commonespecially for vegetarians, vegans, or individuals with absorption issues
Labs employ techniques like turbidimetry or immunoturbidimetry to analyze blood samples and accurately determine the concentration of ferritin in the body
This mechanism becomes clinically important when using high-dose oral supplements (typically 1000 micrograms or more), as it can provide adequate absorption even when the intrinsic factor pathway is impaired
For optimal functioning and health, your body requires a good diet containing enough essential vitamins and minerals
The injection can be given every 6 months if due to a dietary deficiency, or 2-3 months if the cause of your low B12 levels is pernicious anaemia
Intrinsic factor antibodies show pernicious anemia, an autoimmune issue causing vitamin B12 not to be absorbed
