A C-Reactive Protein (CRP) test is one that is used to measure the levels of C-reactive protein which is made by the liver that flows in the blood. It is due to inflammation, that this protein gets released into the bloodstream by the liver.
Inflammation is a general process through which the body’s white blood cells (WBCs) and its process of protecting the body against infections from foreign substances such as bacteria and viruses. Inflammation is the body’s defense mechanism against harmful bacteria and viruses and also plays a major role in the healing process. It can also be called a biological response.
Certain cells begin an inflammatory response to trap bacteria and other offending agents or start healing injured tissue. The result can be pain, swelling, bruising or redness.
The problems related to inflammation are asthma, tuberculosis, arthritis, periodontitis, rheumatoid arthritis, sinusitis, heart problems, cancer, alzheimer’s, and in some cases, even diabetes.
Unfortunately, inflammation can cause all sorts of pains such as sharp pain, throbbing pain, constant pain, pinching pain, shooting pain, and stabbing pain. In fact, biochemical processes can also induce pain as they affect how nerves act.
A CRP test is done to look for underlying diseases and problems. Inflammation is just a reaction which causes uncomfortable and unexplained pains. Hence, the CRP test may be useful for various screening tests.
An infection is again a response by the body due to some bacteria or virus. This includes pneumonia, sepsis, skin infection, etc.
In this type, inflammation remains for a longer time period. It can last months and even years and can cause conditions such as:
The CRP test is a general test for checking inflammation in the body. However, it is used to detect if someone is having symptoms that are related to an inflammatory or non-inflammatory condition. The CRP test helps in determining several other conditions such as:
According to several studies, high levels of inflammation is also related to fatigue.
CRP test is sometimes also used to predict the progression of COVID-19.
A CRP test is a blood test that does not require fasting. One can resume normal and daily activities, however, there may be some swelling and redness around the injection site.
This test is usually performed along with the ESR blood test, AKA Erythrocyte Sedimentation Rate which is primarily a blood test performed to check inflammatory activities in the body. It measures how quickly erythrocytes (red blood cells) settle at the bottom of the testing tube, which indicates the level of inflammation in the body.
The CRP test is measured in milligrams per liter (mg/L) or milligrams per deciliter (mg/dL). The CRP levels can either be high or low depending upon the levels of inflammation in the body. Based on the levels, the doctor narrows down the possible causes of this inflammation which leads to various illnesses.
Levels in the CRP test results:
20-50 mg/l is the level that is considered highly dangerous in COVID patients. Reports suggest, patients with severe disease courses had a far elevated level of CRP than mild or non‐severe patients.
CRP normal value is usually less than 6 mg/l and it is considered to be safe in the case of inflammation. If in any case the values are between 10-100 mg/l, immediate medical assistance is required.
If you or anyone you know is facing issues such as unexplained pains and pain in the joints or muscles, book a blood testing lab as soon as possible.
