What Is C-Reactive Protein?

An overview of the C-Reactive Protein Test

The presence of a C-Reactive Protein in the body stems from a reaction generated by the liver when there are signs of breakout, infection or swelling.

A significant degree of C-Reactive Protein in the body may be a characteristic of infections. This may have occurred due to a virus or cancer in the body.

It could also indicate the presence of acute inflammation in the heart region, which often leads to cardiac arrest. Nonetheless, C-Reactive Protein tests can detect provocative situations in varied circumstances.

Reasons for a CRP Test

A CRP test would be done when a provocative disease such as cancer, infections, etc., is suspected to be present in the body. Although this test may point out that there is acute inflammation, it does not specify where it is situated or what could be its cause. For persons who have had provocative issues in the past, the CRP test will also be carried out to detect if it was taken care of.

Most importantly, a super-sensitive CRP test indicates diseases like stroke, cardiac arrests, etc. it also estimates a meagre degree of protein in the body which could still point out the presence of these diseases. A super-sensitive CRP differs from a typical CRP test as this can only disclose various causative disorders. If your test results show that you have a heart condition, your doctor may recommend a hypersensitive C-Reactive Protein test.

C-Reactive Protein and Cardiovascular Disease

According to an American Heart Specialist’s Judgement in 2019, in assessing possible threats, people who have C-Reactive Protein higher than or equate to 2mg per litre might require drastic actions to deter heart disease.

Applying greater C-reactive protein degrees may help signal people who require a proper observation or thorough medication after cardiac arrest or surgery.

According to the CDC, the following are considered crucial threat characteristics for generating a cardiac disease:

  • Sugar disease
  • Hypertension
  • Hypercholesterolemia
  • Smoking cigarettes
  • Ketogenic diet
  • Inertness
  • Dipsomania
  • Corpulence
  • Inherited cardiac disease.

Things to do in preparing for your CRP Test

There are no particular laid out preparatory measures to follow, but it is recommended that you feed as you usually would as this test can occur during any hour of the day. This test often involves the use of a syringe to draw blood specimens.

Factors to anticipate during the CRP test

Blood would be drawn from your vein by a medical professional. This blood specimen is usually drawn from your elbow region or the hand.

The healthcare worker would first clear the vein area, fasten a band around your arm to then inject the vein to draw blood.

Subsequently, the nurse will take out the band and apply cotton to the site to regulate the blood flow.

Are there possible dangers with the test?

It has been certified that there are no dangers related to this test aside from the typical issues that arise with any blood test. The following are the fundamental issues that you would notice:

  • A subtle tinge when the syringe is injected
  • A minor bruise at the site where the needle is injected.

If you are uncomfortable with needles, speak with your doctor to find means of making it easy.

Outcomes of a C-reactive test

Your doctor will often analyse your results, but generally, CPR test result is often scaled in milligrams per decilitre or milligrams per litre. The results would always look like this:

A normal result: lower than 10miligram per litre

A hypersensitive result: Equating to or higher than 10miligram per litre.

What does having a high C-reactive protein test entail?

As reported by an American organisation trusted authority in 2003, people who have a greater degree of C-reactive protein are more inclined to have a cardiac arrest than those with reduced degrees of C-reactive protein.

Another study from a secured authority in 2013 also verified one hundred people with dangerous heart disease. Investigators showed that a C-reactive protein degree of 10 milligrams per litre in ten years was attributed to a 4% danger of generating a deadly heart disease.

In conducting your tests, if your doctor detects that you may be in danger of cardiac disease, a high sensitive C-reactive blood examination will be included, among other tests that will be carried out.

Moreover, contemporary study shows that the C-reactive protein test may also be used to ascertain other conditions associated with lung disease.

In cases where your doctor feels you have other indications of provocative diseases asides the heart disease, they may recommend a routine C-reactive protein test to deduce the following:

  • Enteritis
  • Rheumatism
  • Systemic lupus erythematosus

What you are expected to do in cases of high C-reactive Protein

Reducing your C-reactive protein test does not guarantee a reduced danger of heart or immunological diseases.

CRP is a measurable indicator of the severity or presence of some disease state but not a specific detector.

According to authorities in 2015, consuming a nutritional diet including fruits may reduce the level of your C-reactive Protein.

When your doctor realises that you are in great danger of heart disease, they may suggest medication to reduce your cholesterol level.

The intake of vitamin C has also been employed to reduce C-reactive protein degrees for people with heart disease.

Research has also pointed out that bacteria in the body also influence reducing C-reactive protein.

Nevertheless, further studies have to be carried out to ascertain these claims.


The presence of a C-Reactive Protein in the body stems from a reaction generated by the liver when there are signs of breakout, infection or swelling. A CRP test is often recommended when you are suspected of having an increased degree of infection to identify the primary factor responsible for the condition.

If the C-reactive protein test does not state the cause of your infection, the doctor uses this diagnosis to determine your problem.A high degree of the C-reactive protein percentage points to the danger of cardiac disease.

Consult your doctor if you notice lasting discomforting differences in your body. Your doctor may decide on a C-reactive protein test.
