What Is a High Sensitivity C-reactive Protein (hs-CRP) Test?
The high sensitivity C-reactive protein (hs-CRP) test measures very small amounts of C-reactive protein (CRP) in your blood. CRP is a protein produced by the liver when there is inflammation in the body. Unlike the standard CRP test, which is used to detect infections and active inflammatory conditions, the hs-CRP test is designed specifically to assess your risk of developing heart disease. It is also known as hs-CRP test, cardiac CRP test, high sensitivity CRP test, or ultra-sensitive CRP test. A small blood sample drawn from a vein is all that is needed.
What Does a High Sensitivity C-reactive Protein (hs-CRP) Test Measure?
The high sensitivity C-reactive protein (hs-CRP) test detects and quantifies CRP at very low concentrations in the blood. This level of precision makes it useful for spotting ongoing, low-grade inflammation that a standard CRP test might miss entirely.
The table below summarises what the test analyses:
| Parameter | What It Tells You |
|---|---|
| hs-CRP (mg/L) | The level of C-reactive protein in the blood, used to estimate chronic low-grade inflammation and cardiovascular risk |
Because CRP levels can rise dramatically in response to even minor tissue injury or inflammation, the high sensitivity C-reactive protein technique provides a more accurate picture of baseline inflammation linked to heart disease risk.
Why Is a High Sensitivity C-reactive Protein (hs-CRP) Test Done?
Doctors order the hs-CRP test to assess cardiovascular risk, particularly in people who sit in an intermediate risk category. It is also used to monitor inflammation in those with known chronic conditions.
Common Symptoms That May Require This Test
Your doctor may suggest this ultra-sensitive CRP test if you experience any of the following:
- Unexplained tiredness or fatigue
- Persistent muscle or joint aches
- High blood pressure
- High cholesterol levels
- A family history of heart disease
- Obesity or a high body-mass index
- A diagnosis of diabetes
Conditions This Test Can Help Detect
The cardiac CRP test can help identify or assess risk for the following conditions:
- Atherosclerosis (the hardening and narrowing of arteries)
- Increased risk of heart attack (myocardial infarction) or stroke
- Peripheral vascular disease (reduced blood flow to the limbs)
- Inflammatory conditions such as rheumatoid arthritis and systemic lupus erythematosus (SLE)
- Chronic infections or autoimmune disorders
High Sensitivity C-reactive Protein (hs-CRP) Test for Chronic Disease Monitoring
For people already living with cardiovascular disease or chronic inflammatory conditions, regular hs-CRP testing can track how well treatment is working over time. Because CRP levels can vary from day to day, most guidelines suggest two measurements taken at least two weeks apart before drawing firm conclusions about cardiovascular risk.
How to Prepare and What to Expect
No special preparation is needed for this test. The process is quick and straightforward.
Do You Need to Fast?
No, fasting is not required before the hs-CRP test. You can eat and drink as normal. However, if your doctor has requested a lipid profile alongside this test, you may need to fast for those additional tests, so check with your doctor in advance.
Practical Tips Before Your Test
A few simple steps will help ensure accurate results:
- Avoid getting the test done if you currently have a cold, infection, or acute illness, as these temporarily raise CRP levels
- Inform your doctor about all medications and supplements you take, particularly statins, NSAIDs (pain relief medicines), or hormone therapy
- Drink enough water before the test to keep your veins accessible for blood collection
- Avoid intense physical activity on the day of the test, as strenuous exercise can briefly raise CRP levels
- Wear a loose-sleeved top to allow easy access to the arm for blood collection
Step-by-Step Procedure
Here is what you can expect during the sample collection:
- A trained phlebotomist (a person who specialises in drawing blood) will ask you to sit comfortably and roll up your sleeve.
- The skin over the chosen vein, usually inside the elbow, is cleaned with an antiseptic wipe.
- A soft elastic band is placed around the upper arm to make the vein more visible.
- A fine, sterile needle is gently inserted into the vein to draw a small blood sample.
- The needle is removed, and a small piece of cotton or a plaster is placed over the site. The whole process takes only a few minutes.
- The labelled sample is sent to the laboratory, where it is analysed using specialised techniques that measure protein levels in the blood.
Factors That Can Affect Accuracy
Several factors can influence your hs-CRP test result:
- Recent infection, illness, or injury can temporarily raise levels
- Smoking, ageing, and obesity are associated with higher baseline hs-CRP
- Hormone therapy (oestrogen or progesterone) may increase levels
- Chronic inflammatory conditions such as rheumatoid arthritis or kidney failure can cause persistently elevated readings
- Certain medications, including statins and NSAIDs, can lower CRP levels
Understanding Your High Sensitivity C-reactive Protein (hs-CRP) Test Results
Your high sensitivity C-reactive protein (hs-CRP) test results will be expressed as a CRP concentration in mg/L and placed into a cardiovascular risk category. Always review your results with your doctor, who will consider your full clinical picture.
| hs-CRP Level | Interpretation |
|---|---|
| 0.5-1.0 mg/L | Low risk of coronary artery disease |
| 1.0 to 3.0 mg/L | Moderate risk of coronary artery disease |
| > 3 mg/L | High risk of coronary artery disease |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how your results should be read:
- Pregnancy and use of oral contraceptives may raise hs-CRP levels, which can make cardiac risk interpretation less straightforward.
- Chronic conditions such as rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease can cause persistently high CRP, complicating its use as a pure cardiovascular marker.
- Kidney dysfunction may produce CRP elevations unrelated to inflammation elsewhere in the body.
- Some antibiotics, particularly carboxypenicillins, can cause artificially low CRP readings in laboratory samples.
- CRP levels tend to be slightly higher in women than men and generally increase with age.
How to Maintain Healthy Levels
General lifestyle habits can support lower inflammation over time:
- Follow a diet rich in fibre, vegetables, and healthy fats. Research suggests a Mediterranean-style eating pattern may meaningfully reduce hs-CRP levels.
- Exercise regularly and maintain a healthy body weight, as both obesity and physical inactivity are linked to higher CRP.
- Avoid smoking, limit alcohol, and find practical ways to manage stress day to day.

Frequently Asked Questions
Both tests measure the same protein, but they work at different levels of precision. The standard CRP test is used to detect significant inflammation, such as during an active infection. The hs-CRP test detects far smaller amounts of CRP and is specifically used to assess long-term cardiovascular risk in people who appear otherwise healthy.
The hs-CRP test is particularly useful for adults at intermediate cardiovascular risk, that is, those who are not clearly at low or high risk based on standard markers alone. It is especially valuable for people with high cholesterol, high blood pressure, diabetes, obesity, or a family history of heart disease, where an additional risk marker can help guide decisions about further care.
No fasting is needed before the high sensitivity CRP test. You can eat and drink normally on the day of collection. If your doctor has also ordered a lipid panel or blood glucose test, fasting may be needed. Confirm with your doctor before your appointment.
When a result comes back above 10 mg/L, it is recommended to repeat the test twice, ideally two weeks apart, to confirm whether the elevation reflects cardiovascular risk or a temporary condition such as an infection. Your doctor will advise on the right frequency for your situation.
Yes. Recent illness, infection, physical injury, or intense exercise can temporarily raise CRP levels. This may not reflect your true baseline cardiovascular risk. If you have recently been unwell or very active, let your doctor know, as they may advise waiting before testing.
Yes, certain medications can lower hs-CRP. Statins (cholesterol-lowering medicines) and NSAIDs (pain relief medicines) are both known to reduce CRP levels. Hormone therapy may raise levels. Always inform your doctor about all medicines and supplements you are taking before the cardiac CRP test.
