What Is The C-reactive Protein Test For?

C-reactive Protein (CRP) is a non-specific marker that can indicate the presence of infection and inflammation. It is protein that is part of the innate immune response.

The high sensitivity test can also be used to assess cardiovascular disease risk, as cardiovascular disease is associated with chronic inflammation and CRP levels can be used to track inflammation.

How To Test C-reactive Protein

By buying a laboratory test kit with professional nurse or clinic collection, you can accurately measure C-reactive Protein for total reassurance.

Professional analysis in an accredited laboratory ensures rapid result delivery.

The Vitall Inflammation (CRP) nurse or clinic test kit includes a C-reactive Protein test and is available for just £59.00.

What if C-reactive Protein Results Are High?

An elevated CRP can suggest an acute infection or inflammation. CRP is a non-specific marker, meaning it can rise in many inflammatory conditions, and this test alone cannot identify where the inflammation is coming from or what condition is causing it.

Inflammation can also occur without infection, and CRP cannot distinguish between inflammation caused by infection and inflammation from other causes. After recovery from an infection, CRP can remain raised for a short time because levels may take a little while to fall.

If CRP stays persistently raised, it may indicate an underlying process causing chronic inflammation, which is associated with a number of problems, including an increased risk of heart attacks. Significantly high readings are generally treated as clinically significant and are often reviewed further to clarify the cause, particularly when ongoing.

What if C-reactive Protein Results Are Low?

Low C-reactive protein (CRP) is generally considered more favourable than a high level, because it indicates less inflammation in the body.

A low CRP level on its own is not usually linked with a specific problem.

Who Should Take This Test?

Measure your C-reactive Protein levels and identify the presence of inflammation & its severity with a Inflammation (CRP) nurse or clinic finger-prick bloodtest kit

You get the convenient testing with the reassurance of professional clinical analysis. Your results are delivered quickly & securely online.

This Inflammation (CRP) Test is advised if you:

  • want the convenience of home testing without waiting for a GP appointment;
  • need a high quality, clinically accredited test done in a professional clinical laboratory.

How accurate is the CRP test from Vitall?

The CRP test from Vitall is highly accurate as samples returned are analysed by a UKAS accredited laboratory.

Is the CRP test a substitute for a medical check-up?

No, the CRP test should not be used as a substitute for a complete medical check-up. It's a useful tool in checking for inflammation, but it is just one aspect of diagnosing an ailment. If you are feeling unwell or have concerns, it's crucial to seek advice from a healthcare professional.

What do I do if my CRP test results are negative?

If your CRP test results are low, it generally means you do not currently have inflammation from the conditions this test helps to diagnose. Nevertheless, if you are experiencing symptoms, it's still important to consult a healthcare provider for further evaluation.

What should I do if my CRP test results are positive?

If your CRP test results are high, it indicates inflammation in your body. You should seek consultation from a healthcare provider who can evaluate your history, symptoms and other relevant factors to give an accurate diagnosis.

How can I interpret the results of my CRP test?

High levels of CRP may indicate the presence of inflammation in your body due to a variety of conditions. However, interpretation of results should be done in context with your symptoms. The disease causing the inflammation may not be known just from the test results.

How do I use the Vitall CRP test kit?

The Vitall CRP test kit is simple to use. Follow the instructions provided to prick your finger and apply a small amount of blood to the sample collection device. You then send this back to a UKAS accredited laboratory in the pre-paid, sealed package.

How does the C-reactive Protein test kit work?

The test kit includes everything needed to prick your finger and collect a small sample of blood. You then mail the sample to a UKAS accredited laboratory using the pre-paid package provided. Lab professionals analyse the sample and your results are sent securely to you.

What symptoms may prompt me to take a CRP test?

Symptoms prompting a CRP test may include unexplained fatigue, ongoing body aches, unexplained weight loss, persistent fever, or any other persistent symptoms related to inflammation.

What conditions can the CRP test help to diagnose?

The CRP test can help to diagnose conditions that cause inflammation. These can include bacterial infections, fungal infections, autoimmune diseases such as lupus or rheumatoid arthritis, inflammatory bowel disease, and heart disease.

What is a C-reactive Protein (CRP) test?

A C-reactive Protein (CRP) test is a blood test that measures the level of CRP in your blood. CRP is a protein produced by your liver in response to inflammation. High levels of CRP in the blood can indicate inflammation caused by various health conditions such as infections, heart disease, and autoimmune diseases.
