Folate is needed by the body in your diet every dayIt plays a role in DNA replication and protection, it’s important for the production of red blood cells as well as in the prevention of neural tube defects in babies.

Low levels can indicate anaemia and can be implicated in raised homocysteine levels.

The test measures the volume of iron within your blood with the aim of diagnosing iron deficiency anaemia or iron overload syndrome (haemochromatosis).

The symptoms of too little or too much iron can be very similar I.e fatigue, muscle weakness, moodiness and difficulty concentrating

Ferritin is a protein which stores iron in your cells for your body to use later. Measuring ferritin levels gives us a good indication of the amount of iron stored in your body.

Low levels of ferritin can indicate anaemia which can be caused by excessive or chronic bleeding, poor absorption of iron or too little iron in the diet.

Raised ferritin levels can indicate iron overload syndrome (haemochromatosis) or any kind of liver damage. It is also a marker of infection and inflammation.

Total Iron Binding Capacity (TIBC)
measures how well the blood and iron bind to each other.

It can be used alongside other iron tests to help diagnose iron deficiency

A transferrin saturation test tells us how much iron in the blood is bound to transferrin.

A low transferrin saturation usually indicates iron deficiency

Magnesium is an abundant mineral which the body needs for energy production, nerve function and muscle contraction.

Magnesium is sourced through the diet,
