Your immune system is essential for protecting you from infections, viruses and disease, and also supports healing when you injure yourself. Our immunity blood test gives you a clear reading of the key biomarkers involved in supporting your immune health, so you can identify the areas that need improvement.
As well as measuring your full blood count, the immune blood test measures the essential nutrients needed to support your immune system such as ferritin, active B12, folate and vitamin D and keep it working efficiently.
White blood cells are the major components of the immune system. They help to protect your body from invading pathogens and infectious diseases. There are 5 types and they each have specific jobs within the system to help protect the body.
Our immunity blood test will show you your levels of these immune system cells but it will also provide you with a full blood count including red blood cells. Red blood cells are important for carrying oxygen around the body to the tissues that need it. Oxygen is essential for producing energy, a vital requirement during an immune response.
You’ll also gain a good understanding of your micronutrient levels such as ferritin, folate and active B12 which are essential for the production of red blood cells and their oxygen-carrying capacity.
Vitamin D is also measured which is not only vital for bone health, but is important for the regulation of the immune system. Some research shows that vitamin D deficiency can lead to an increased risk of autoimmunity, where your immune cells attack your body cells by mistake causing damage and illness.
A healthy, balanced diet will ensure you are getting all the essential vitamins and minerals your body needs to support its immune system.
These nutrients are critical for good immune function:

Weaken immune systems are generally caused by primary immune disorders.
Primary immune disorders are present from birth and people with this disorder are missing some of the body’s immune defenses, or have an impaired immune system that is not working properly.
However, other factors can cause a weak immune system such as some medical treatments, some types of cancer, and malnutrition.
People with a weakened immune system tend to get infections more often and it takes the body longer to fight them off. A weakened immune system can also lead to autoimmune disorders, digestive issues, inflammation of internal organs, and anemia.
It is not uncommon for adults to have 2 to 3 colds a year, but a poor diet and lifestyle can make it harder to fight off colds and infections.
A high white blood cell count is called leucocytosis and can indicate several things, including:
Having a good, balanced, healthy diet and the right amount of sleep each night is a good way to help your body fight off common infections and viruses. Good hygiene such as regularly washing your hands can also protect you against catching viruses.
Sleep is key to fighting off any infections which is why we are advised to get plenty of rest when we are ill. This is because your immune system releases proteins called cytokines some of which need to increase when you have an infection. So if you do not rest enough when you are ill, your immune system has less chance to release these proteins.
A good diet is also essential for supporting your immune system so ensure you are getting key vitamins such as vitamin B12, vitamin B9 (folate), and vitamin D, as well as iron.
Last but by no means least, is hydration. Hydration plays an important role in protecting us from infection as it encourages the production of saliva which contains high levels of IgA, the body’s first line of defence.

Yes. When we are stressed our bodies release the stress hormone called cortisol. Too much cortisol can impact the immune system as it decreases the level of lymphocytes – white blood cells – in the body. Lymphocytes are needed to help the body fight off infection.
In addition, stress can make us adopt more unhealthy lifestyles, such as drinking more alcohol and eating more unhealthy, high fat, high sugar foods. Research has also shown that spikes in sugar consumption can suppress the immune system.
