A three-marker blood test measuring active vitamin B12, folate and vitamin D, for checking common nutrient deficiencies linked to energy, mood and immune health.
Cheapest 3-marker B12, folate and ferritin test here
This test measures active B12, folate and ferritin together, three markers linked to energy, red blood cell production and possible anaemia. It suits people with fatigue, dizziness or a suspected deficiency who want a broader check than a single marker.
Pricier and narrower than Medichecks' own 3-marker test
This test measures active vitamin B12 and folate, two nutrients involved in energy, brain function and red blood cell production. It suits people who want to check both markers together, such as vegans, vegetarians or those with absorption issues.
