CRP Test: What It Is, Why It’s Done, and What Your Results Mean

Introduction to the CRP Test

The CRP test, also called the C-reactive protein test, is a simple blood test. It checks for inflammation in your body. Doctors often use the CRP test to help find out if you have an infection or another health problem. Because it is quick and easy, many people get a CRP test when they feel unwell. In this blog, you will learn what the CRP test is, why it is done, and what your results mean.

What Is a CRP Test?

A CRP test measures the amount of C-reactive protein in your blood. C-reactive protein is made by your liver. When your body has inflammation, your liver makes more CRP. Inflammation can happen for many reasons, such as infection or injury. Since the CRP blood test is simple, it helps doctors find out if there is a problem in your body.

Why Is the CRP Test Done?

Doctors order a CRP test for several reasons. Sometimes, you may have symptoms like fever, pain, or swelling. In these cases, the test helps find out if inflammation is present. Other times, the CRP test is used to:

Check for infections, such as pneumonia or sepsis

Monitor chronic diseases, like arthritis or lupus

See how well treatment for inflammation is working

Help diagnose other health problems that cause swelling or pain

For example, if you have a high fever, your doctor may order a CRP test to check for infection. In some places, you may hear about the “CRP test in [City/Country]” when looking for local labs.

How Is the CRP Test Performed?

The CRP test is quick and safe. A healthcare worker will take a small sample of blood from your arm. Usually, the steps are:

First, your arm is cleaned with alcohol.

Next, a small needle is used to draw blood.

Then, the blood is sent to a lab for testing.

Finally, you can go home right after the test.

Most people feel only a small pinch. Afterward, you may have a tiny bruise, but it goes away quickly. Because the test is simple, you do not need to stay at the clinic for long.

What Do CRP Test Results Mean?

CRP test results show how much C-reactive protein is in your blood. Here is what the results may mean:

Normal CRP level: Usually less than 10 mg/L. This means there is little or no inflammation.

High CRP level: Above 10 mg/L. This can mean you have inflammation, infection, or another health problem.

However, a high CRP test result does not tell you the exact cause. For example, it may be due to a cold, a serious infection, or a long-term disease. Your doctor will look at your symptoms and other tests to find the cause. Sometimes, a very high CRP level can mean a serious infection or injury. But mild increases can happen with minor illnesses.

How to Prepare for a CRP Test

Most people do not need to do anything special before a CRP test. You can eat and drink as usual. However, always follow your doctor’s advice. If you take medicine, let your doctor know. Some medicines can affect your CRP levels. Because the test is simple, you can return to your normal activities right after.
