Mineral Check

About this test

Minerals are essential to the functioning of the entire body. Some minerals are present in large amounts such as calcium. Others like manganese exist in trace amounts but are critical to the body's overall health and wellbeing.

The most common mineral / trace element deficiency is iron dificiency.

Additional calcium is sometimes needed to treat osteoporosis and iodine may be added to salt in areas where a dietary deficiency may occur.

Mineral supplements may be recommended, by a doctor, for those who have intestinal disorders that prevent proper absorption of minerals.

Who is this test for?

This test is for individuals who are worried they may be deficient in important minerals due to dietary insufficiency or malabsorbtion. This test is also for those who may be suffering symptoms consistent with a mineral deficiency.

Important Information

Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. Our doctors will interpret your results based on the information you have provided, but will not diagnose, consult or provide any treatment. You will be advised to see your doctor for any necessary follow-up action.

Tests Included


This test measures how much iron is in your serum with the aim of identifying iron deficiency anaemia or iron overload syndrome (haemochromatosis)

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

A raised result can mean that you have iron overload syndrome, an inherited condition where your body stores too much iron, or that you are over-supplementing or that you have a liver condition.

A low result can mean that you are anaemic or are suffering from gastro-intestinal blood loss (or other blood loss). Anaemia is also very common in pregnant women. 

Magnesium is an important mineral needed for proper muscle, nerve, and enzyme function. It helps the body make and use energy and aids the movement of electrolytes such as potassium and sodium into and out of cells.

The kidneys remove any excess magnesium from the body so developing raised magnesium levels (hypermagnesemia) is rare. However, those with kidney problems and those supplementing high amounts of magnesium may be at risk of developing hypermagnesemia.  

A low magnesium level can be caused by poor nutrition and a high intake of alcohol.  Magnesium is found in a variety of foods including nuts, leafy green vegetables, legumes and whole grains. 

Zinc is necessary for immune function, wound healing, taste, smell and is essential for cell division and growth. Zinc also removes toxic metals such as copper, lead and mercury from the brain. 

Even though zinc is an essential requirement for a healthy body, too much zinc can be harmful. Care is needed when taking zinc supplements as it is possible to overdose on zinc. A raised zinc result may be due to over supplementing.

A low result may be caused by a lack of zinc in your diet. Zinc can be found in red meat, poultry, pulses, seeds and nuts.
