Detecting acute inflammation: Identify the presence and severity of acute bacterial infections, such as pneumonia, appendicitis, or sepsis. Monitoring chronic diseases: Track disease activity and response to treatment in chronic inflammatory conditions like rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease. Assessing future heart risk: Using high-sensitivity CRP (hs-CRP) as a predictive marker for cardiovascular risk, as mild chronic elevation is associated with arterial inflammation. Distinguishing infections: Help differentiate bacterial infections (marked CRP elevation) from viral infections (slight or no elevation) in some cases.

Patients with acute symptoms: Those showing signs of infection or acute inflammation, such as fever or localized pain. Chronic immune disease patients: Individuals with rheumatic or autoimmune conditions for regular monitoring of disease activity. Cardiovascular risk patients: Individuals at risk of heart disease, as a supplementary test for risk assessment. Post-surgery patients: Patients after surgical procedures to detect early complications like inflammation or infection.

Unexplained high fever: Accompanied by persistent or recurrent chills. Joint pain and swelling: Redness or warmth in one or more joints. Severe abdominal pain: Could indicate an internal inflammatory condition requiring prompt evaluation. General infection symptoms: Such as extreme fatigue, body aches, or general weakness.

Normal (adults and children): usually below 5-10 mg/L. Some labs consider less than 3 mg/L as normal. Normal/mild: 200 mg/L (indicates severe bacterial infection or sepsis).

hs-CRP Inflammation Test | Lahalak Medical Platform

An advanced test measuring C-reactive protein levels with extreme precision to detect silent inflammation and potential health risks early, ensuring a healthier and safer life.

Scientific name: High-Sensitivity C-Reactive Protein Test (hs-CRP)

High-sensitivity quantitative test (hs-CRP or CRP quantitative) measures the concentration of C-reactive protein (CRP) in blood serum with precision. CRP is an acute-phase protein produced by the liver in response to inflammatory signals (cytokines such as interleukin-6). Its level rises rapidly (within 6–12 hours) from the onset of inflammation or...

Frequently Asked Questions (FAQs)

Difference between standard CRP and high-sensitivity CRP (hs-CRP)? Standard CRP: Used to diagnose and monitor acute and active infections. It typically measures higher levels, usually above 5-10 mg/L. High-sensitivity CRP (hs-CRP): Measures the same molecule with much greater precision to detect very low levels below 5 mg/L. It is mainly used to assess cardiovascular risk, as a slight chronic elevation (up to 3 mg/L) indicates inflammation in the arteries.
Can CRP rise for reasons other than infection? Yes, CRP can increase in many non-infectious conditions causing inflammation or tissue damage, such as: Acute myocardial infarction (heart attack). Major trauma or surgery. Severe burns. Active rheumatic diseases (e.g., rheumatoid arthritis). Certain types of cancer. Immune reactions.
Acute myocardial infarction (heart attack).
Major trauma or surgery.
Severe burns.
Active rheumatic diseases (e.g., rheumatoid arthritis).

Normal Levels

Normal (adults and children): usually below 5-10 mg/L. Some labs consider less than 3 mg/L as normal.
Normal/mild: < 10 mg/L.
Moderate elevation: 10 - 40 mg/L (often indicates mild localized or viral inflammation).
Significant elevation: 40 - 200 mg/L (usually indicates severe bacterial infection or systemic inflammation).
Severe elevation: > 200 mg/L (indicates severe bacterial infection or sepsis).

Conditions & Notices

• Fasting is not required for this test, unless it is requested as part of a test package that requires fasting.
• The sample is collected in a serum tube (red or yellow cap).
• No special preparations are required, but the physician should be informed of any recent infection or inflammation, or any medications (such as statins or anti-inflammatory drugs) that may affect the level.
• For hs-CRP testing to assess heart risk, the patient should be free from any acute infection or inflammation for at least two weeks, as acute inflammation will significantly raise the result and give a misleading reading of long-term risk.
