Vitamin B12 Test (Active B12)
£65
Why This Test Is Important
Vitamin B12 is essential for energy production, nerve health, and red blood cell formation. Testing helps detect deficiencies that can cause fatigue, weakness, memory issues, or anemia, ensuring you maintain optimal energy and neurological function.
Unlike Total B12 - Active B12 measures only the biologically active form of vitamin B12 that your body’s cells can absorb and use. It gives a more accurate picture of your true B12 status and is often an earlier indicator of deficiency.
What's Included
- Vitamin B12 (Active B12)
Important Pre-Test Information
