Why Test Your
CRP Levels?

CRP or C-reactive protein, is a biomarker for inflammation. It is a protein that increases when there are high levels of inflammation present, and so can be good indicator of infection, injury, or a poor diet. As inflammation is linked to heart disease, lowering your levels will help to keep your heart healthy.

CRP will increase immediately in response to intense exercise but should return to normal within 20 hours. So, if you’re an athlete or exercise regularly, measuring your CRP level can  help you to calculate the recovery time needed between sessions or after and event. 

When to take This test

The best time to take the test is between 8am and 10am. As CRP levels rise dramatically following exercise, it is best to carry out the test before you workout or a few days after.

What Causes Inflammation In The Body?

Inflammation is the body’s natural response to fighting off things that it thinks will harm it like toxins, bacteria, viruses and injuries and is part of the body’s immune response.

If an invader or an injury is detected, an immune response is triggered and the cells in your immune system release chemicals and antibodies to help fight it off as well as increasing blood flow to the affected area. That’s why you may get symptoms such as redness, swelling and heat around the site of infection or inflammation. This type of inflammation is acute and usually only lasts for a few hours or days.

Medical experts now recognise that the build-up of fatty plaques in the artery walls (known as atherosclerosis), is an inflammatory process. Because the inflammation it causes is low level but long-term, a high sensitivity test can detect even small increases of C-reactive protein in the blood.

What is chronic inflammation?

Chronic inflammation, on the other hand, occurs when the inflammatory response by your body is prolonged and is constantly in a state of alert.

This type of inflammation is believed to play a key role in the development of chronic illnesses such as heart disease and cancer.

Causes of chronic inflammation include:

  • Untreated infections or injuries
  • Autoimmune conditions
  • Smoking
  • Poor diet
  • Obesity
  • Stress
  • Alcohol consumption

By understanding the levels of inflammation in your body you can help reduce your risk of chronic disease by implementing lifestyle changes and keep your body in the best of health.

Frequently asked questions

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

  • What should CRP levels be?

    The normal level of CRP is between 0 – 5 mg/L.

  • Can I improve my result?

    Yes, if your CRP levels are raised because of low-grade inflammation linked to obesity, smoking, diet, or alcohol, then there are changes you can make to your lifestyle to help reduce your result.

    For example, eating a Mediterranean style diet that is high in fruit, vegetables, whole grains, nuts, and fish has been shown to lower inflammation in people who are overweight or have type 2 diabetes.

    Cutting down alcohol to less than 14 units per week can also help to improve results.

    Finally, if you exercise regularly, ensure you are giving your body enough time to recover between sessions.  CRP levels can take 20 hours to recover after exercise.

  • What does it mean if I have a high CRP level?

    If you exercise regularly, raised CRP levels can indicate that you are not giving your body enough recovery time between intense periods of exercise.

    High CRP levels can also indicate an infection within the body as a result of toxins, bacteria, viruses, and injuries.

    Raised levels of C-reactive protein can also indicate an increased risk of developing heart disease.

    It can also indicate that you have a bacterial infection or have an autoimmune condition like:

    • Rheumatoid arthritis
    • Lupus
    • Inflammatory bowel disease (IBD)

    Knowing you have high levels of CRP will enable you to look into other areas of your health, such as cholesterol levels, and make changes to your lifestyle in order to lower the level of inflammation in the body.
