Here in this article, we will tell you what is a CRP test and how it can help COVID patients.
CRP stand for C-reactive protein. It is a test that helps in detecting the presence of inflammation or infection in the body. It is a commonly used blood test to detect the increased levels of infection in the body. A raised CRP level has been observed in most people suffering from COVID infection.
What is inflammation?
Inflammation is an umbrella term used to describe the release of chemicals involved in the immune system. CRP test integrates signals from various proteins involved in inflammation, called cytokines, which provides physicians with a picture of a person’s inflammatory activity within a few hours.
A higher CRP level indicates that the infection in the body is increasing. C-reactive protein is made by the liver in the blood.
Even if the person has normal SPO2 levels and the CRP levels are more than 70 mg/L, it can be an indication of an impending cytokine storm, which may be calling for immediate medical attention.
Normal CRP levels
The normal CRP concentration levels range from 30-50 mg/L.
Why does the CRP increase in COVID-19?
The overproduction of inflammatory cytokines can lead to a raised level of CRP level. The cytokines fight against the pathogens, but when the system is in a hyperactive mode, it can damage the lung tissues.
Who must take the CRP test?
As per experts, for patients with mild to moderate COVID symptoms, a CRP test is not necessary unless the patient has any severe symptoms even after passing the 5 days of infection.
People who have severe symptoms during any time of the infection must get their CRP test done. When done on time, the test can reduce the possibility of the infection turning in severity from mild to moderate.
How is the CRP test done?
A blood sample is taken to measure the CRP levels in your body. The process usually takes less than a minute and feels like a sting.
