Check CRP value
✔ Sensitive marker for infections
✔ Relevant for inflammations
✔ Important for prevention
What is C-reactive protein (CRP)?
The C-reactive protein, or CRP, is a protein produced in the liver. Whenever an inflammation occurs in the body – for example, due to an infection, an injury, or a chronic disease – the concentration of this protein in the blood increases.
CRP is one of the so-called acute-phase proteins. This means that the level already rises measurably a few hours after the onset of an inflammatory reaction. This is precisely why it is so important in medical diagnostics.
The CRP level itself does not cause any symptoms. It serves as an objective laboratory parameter to make inflammatory processes visible and to monitor their progression.
Reference ranges
Under 5 mg/L: Normal range
5–10 mg/L: Mild inflammation possible
Over 10 mg/L: The CRP level is too high – possible acute inflammation or infection
Important: An elevated CRP alone does not constitute a diagnosis and must always be evaluated in the overall medical context and with other biomarkers.
Causes of elevated CRP levels
If the CRP level is elevated, it indicates an inflammatory reaction in the body. The causes can be varied.
Acute infection
Acute infection
Bacterial infections often lead to significantly elevated levels. In viral infections, CRP usually also increases, but often less strongly.
Chronic inflammation
Chronic inflammation
Diseases such as rheumatism, arthritis, or chronic inflammatory bowel diseases can cause permanently elevated levels.
Cardiovascular disease.
Cardiovascular disease.
Slightly elevated CRP levels in the range of approximately 1–3 mg/L may indicate an increased risk of vascular diseases and are therefore relevant in prevention.
Autoimmune diseases
Autoimmune diseases
If the immune system attacks the body's own structures, increased inflammation levels can also be measured.
Injuries and surgery
Injuries and surgery
After injuries or surgical procedures, CRP increases as the body activates healing processes.
CRP in medical diagnostics
The CRP value is usually not considered in isolation. It serves as a supplementary marker to assess inflammation in the body and monitor its progression.
Especially in chronic diseases, regular measurement helps to objectively evaluate changes and monitor therapy progress.

FAQ: Frequently Asked Questions about Stress, Burnout, and Cortisol Levels
CRP value — what is it and why is it important?
CRP value — what is it and why is it important?
The CRP value (C-reactive protein) is an inflammation marker in the body. It indicates whether there is an acute or chronic inflammation and is often used to assess the severity and cause of inflammations.
How is the CRP value measured?
How is the CRP value measured?
The CRP value is determined by a blood test. A simple blood sample is sufficient to measure the CRP value and detect possible inflammatory processes in the body.
What reference ranges are there for the inflammation marker (CRP value)?
What reference ranges are there for the inflammation marker (CRP value)?
A normal CRP level is below 5 mg/L. Values between 5 and 10 mg/L indicate a mild inflammation, while values above 10 mg/L may suggest an acute inflammation or infection. A high CRP level is often a sign of a severe inflammation.
What can elevated CRP levels mean?
What can elevated CRP levels mean?
An elevated CRP level indicates an inflammatory reaction in the body. If the CRP level is elevated, it can have several causes. Possible causes include bacterial infections, autoimmune diseases, injuries, or chronic inflammations such as arthritis. Cardiovascular diseases can also be associated with slightly elevated CRP levels.
What symptoms can indicate a high CRP level?
What symptoms can indicate a high CRP level?
Since the CRP value is only a marker for inflammation, it does not indicate any specific symptoms itself. However, symptoms of inflammation can include fever, pain, swelling, fatigue, and redness. A CRP test is often performed to clarify the cause of these symptoms.
What is the difference between CRP and hs-CRP?
What is the difference between CRP and hs-CRP?
The hs-CRP (high-sensitivity CRP) measures very low CRP levels and is often used to assess cardiovascular risk. While the regular CRP test measures acute inflammation, the hs-CRP test indicates subtle inflammation that may be associated with a higher risk of heart disease.
What can I do to lower my inflammation marker (CRP level)?
What can I do to lower my inflammation marker (CRP level)?
A healthy lifestyle can help lower CRP levels. Regular exercise, an anti-inflammatory diet, adequate sleep, and stress management contribute to reducing inflammation. In cases of acute inflammation, treatment with medication may be necessary.
When should the CRP level be checked?
When should the CRP level be checked?
The CRP level should be checked if there is suspicion of an acute or chronic inflammation or if symptoms such as fever, joint pain, or fatigue occur. The hs-CRP level can also be helpful in assessing the risk of cardiovascular diseases.
Can medications affect the CRP level?
Can medications affect the CRP level?
Yes, some medications can affect the inflammatory marker (CRP level). Anti-inflammatory drugs, such as corticosteroids or non-steroidal anti-inflammatory drugs (NSAIDs), can lower the CRP level. Before a CRP test, the doctor should be informed about all medications being taken.
How long does it take for the CRP level to normalize after an inflammation?
How long does it take for the CRP level to normalize after an inflammation?
The CRP level usually decreases within a few days after the cause of the inflammation has been treated. However, in chronic cases, the CRP level may remain elevated for a longer period, requiring regular monitoring.
