The Vitamin B12 (active) blood test is great if you are experiencing symptoms of fatigue, weakness and pins and needles. B12 is essential and can become a deficiency due to factors such as avoiding animal based foods, and diseases like Crohn’s.

This test will show levels of active B12 within the blood stream and ensure that your body is absorbing Vitamin B12.

This test is for people who may have recently been diagnosed with anemia, people who take medication that may absorb vitamin B12 or people that just want to check Vitamin B12 levels within the blood.
