Why Test Your Immune Health?

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.

What Can the
Immunity Test Tell You?

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 provide you with a measurement of your white blood cell count together with red blood cells, including haemoglobin and hematocrit. 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.

Vitamin D levels
79%
of Forth customers were found to have sub-optimal levels of vitamin D (>75 nmol/L).
Vitamin B12 levels
50% of customers
improved their B12 result between tests.

Diet And The
Immune System

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:

  • Vitamins B12 and folate help produce cells involved in the immune system. Good sources include beef, lamb, chicken, milk, cheese, and eggs (B12) and green leafy vegetables, nuts, seeds, and pulses (folate).
  • Iron helps to keep your immune cells healthy as well as being a vital component of haemoglobin in red blood cells, the protein responsible for carrying oxygen around the body. The best sources of iron are red meat and fish but there are plant-based sources including spinach, kale, whole grains, nuts, and dried fruit.
  • Vitamin D is needed for a strong immune response. Most of your vitamin D comes from sunlight exposure but there are some food sources available like eggs and mushrooms. However, everyone in the UK is advised to supplement their intake of vitamin D.

Frequently asked questions

 Here are some of the most frequently asked questions. If you need anything else try our help section.

  • What are signs of a weak immune system?

    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.

  • What do elevated white blood cells indicate?

    A high white blood cell count is called leucocytosis and can indicate several things, including:

    • Bacterial infection
    • Inflammation
    • Injury/trauma
    • Leukemia/blood disorders
  • How can I improve my immune system?

    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.

  • Can stress affect the immune system?

    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.
