Why Test for Vitamin B12 Deficiency?
Vitamin B12 is essential for red blood cell production, nerve function, and DNA synthesis. Deficiency can lead to symptoms such as:
- Fatigue and low energy
- Memory problems and difficulty concentrating
- Pins and needles or numbness
- Pale or jaundiced skin
- Mouth ulcers and a swollen tongue
- Mood changes, including low mood and irritability
Early detection of a deficiency is important to prevent long-term complications, including neurological damage and anaemia.
