CRP Blood Test: The CRP test measures the amount of this protein in the blood. Let us explain which diseases the CRP test can detect and which diseases it can diagnose.

What is a CRP test?

When to get a CRP blood test: When an infection or inflammation occurs in the body, the body automatically recognizes and attempts to fight it. In this process, the liver produces a special protein called C-reactive protein, or CRP. When levels of this protein rise, it indicates inflammation or infection somewhere in the body. This is why doctors often recommend a CRP test for patients. This is a simple blood test, but its results can indicate several serious diseases. Let us tell you when this test is done and at what age it is appropriate to get it done.

What is a CRP test?

Now, let's look at why this test is done. The CRP test measures the amount of this protein in the blood. According to the Mayo Clinic, when there's an infection or injury in the body, the liver immediately increases CRP levels. Normally, the level in the blood is very low, but if the level is elevated, it could be a sign of some type of inflammation or infection.

Which diseases does the CRP test detect?

When the body experiences a serious infection, such as sepsis, CRP levels rise rapidly. The Cleveland Clinic reports that this test helps determine the severity of inflammation in such cases. Furthermore, autoimmune diseases such as rheumatoid arthritis and lupus cause the body to attack its own cells. Elevated CRP levels in these conditions can also indicate disease activity. CRP can also be elevated in inflammatory bowel diseases. A test called hs-CRP is used to assess heart health. If levels are consistently elevated, it may indicate inflammation in the heart's blood vessels and a risk of future heart attacks.

At what age should the CRP test be done?

Generally, not everyone needs this test. However, if you experience frequent infections, persistent fever, joint pain, fatigue, or symptoms of a serious illness, your doctor may recommend it. According to the Times of India, given the increasing incidence of heart disease, it may be beneficial to have an hs-CRP test periodically after the age of 30 to 40, especially if there is a family history of heart disease.
