What does an immune system blood test check?

If you suffer from frequent colds or illnesses, you could have a weak immune system. This test will help confirm if your immune system is functioning properly and if your diet is giving you enough key vitamins to support your immune health, such as vitamin D, B12 and iron.

How to test immune system strength at home

Testing your immune system strength at home has never been easier. The kit fits through your letterbox and comes with everything you need to collect a small blood sample and post it back. Your blood sample is analysed at an NHS lab, where our expert medical team create your report and provide feedback on what your results mean.

What causes a weak immune system?

A weak immune system can be caused by several factors. Chronic stress, lack of sleep, over exercising and poor diet choices can all compromise the immune system’s effectiveness. Certain medical conditions, such as autoimmune disorders or chronic illnesses, can weaken immune responses. Lifestyle factors like smoking, excessive alcohol consumption, and a sedentary lifestyle can also contribute to immune system impairment.

Frequently asked questions​

This is what our customers ask us most about this test. For more information, try our help centre.

  • What vitamins are essential for immune health?

    The following vitamins and minerals have an important role in normal immune system function:

    • Vitamin A
    • B Vitamins
    • Vitamin C
    • Vitamin D
    • Vitamin E
    • Vitamin K
    • Selenium
    • Zinc
    • Magnesium
    • Folate
    • Iron

  • How can I boost my immune system at home?

    It is important to use a blood test to identify any problem areas that could be impacting the immune system’s ability to correctly function. If there are deficiencies in key vitamins and minerals, food supplements are readily available in health food shops, pharmacies, and supermarkets.

    It is also important to manage stress, as this can keep your body in a stress-response state that can impair the functionality of your immune system.

  • Can exercising improve my immunity?

    Not many people realise that the lymphatic system (that connects our lymph nodes) has no pump. Instead, this system relies on our movement to ensure that fluid moves and drains through this system. Exercise can allow the immune system to work more effectively.

    Exercise can also prime the immune system with the increased flow of immune system cells and a post-exercise inflammatory response, effectively putting the body on guard duty.

    Regular moderate exercise can also reduce the amount of inflammation in the body, increasing your immunity.

  • What are the signs of a bad immune system?

    The following can be signs that you immune system is not functioning as well as it could be:

    • having colds frequently
    • wounds taking longer to heal
    • feeling tired all the time as your immune system tries to conserve energy
    • upset stomach, with research showing most of your immune system is focussed in your digestive system

  • How soon will the test arrive?

    If you order your test before midday on a Monday to Friday then your kit will be dispatched the same day.

    All our kits are sent out via Royal Mail first class post, so it should be with you within 1-2 working days.

  • Can I have someone take my blood for me?

    Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.

    A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.

    The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

  • Does a doctor review my results?

    We have a team of doctors and nurses who look at all results and will comment on any results that are outside of the normal range for your age.

  • Can I download the results to share with my GP?

    Yes, you can download your results from your health dashboard as a PDF to share with your GP.

About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don’t worry – you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your health markers change. You’ll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what’s tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.
