What Is A Blood Test

C Reactive Protein Test What does it mean?

By taking and testing a small sample of a persons blood, doctors can check for many kinds of diseases and conditions. Blood tests help doctors check how the bodys organs are working and see if medical treatments are helpful.

To help your child get ready for a blood test, find out if they need to fast or should stop taking medicines before the test. Explain what to expect during the test. If your child is anxious about it, work together on ways to stay calm.

What Are The Causes Of Elevated C

Elevated CRP can signal many different conditions, including cancer, cardiovascular disease, infection, and autoimmune conditions such as rheumatoid arthritis, lupus, and inflammatory bowel disease. The chronic inflammation behind an elevated CRP level may also be influenced by genetics, a sedentary lifestyle, too much stress, and exposure to environmental toxins such as secondhand tobacco smoke. Diet has a huge impact, particularly one that contains a lot of refined, processed and manufactured foods.

What Do The Results Mean

If your results show a high level of CRP, it probably means you have some type of inflammation in your body. A CRP test doesn’t explain the cause or location of the inflammation. So if your results are not normal, your health care provider may order more tests to figure out why you have inflammation.

A higher than normal CRP level does not necessarily mean you have a medical condition needing treatment. There are other factors that can raise your CRP levels. These include cigarette smoking, obesity, and lack of exercise.

If you have questions about your results, talk to your health care provider.

Some Cutoffs Have Already Been Established

Without preset cutoffs, doctors wouldn’t know how to interpret CRP test results. Dr. Paul Ridker, a Harvard researcher, was principal investigator on most of the crucial CRP studies and is co-inventor on related patents. He says it’s now possible to classify CRP levels in terms of low, moderate, or high risk.

Less than 1 milligram per liter of blood corresponds to a low risk for heart attack or other cardiovascular problems 1-3 milligrams per liter corresponds to moderate risk and over 3 milligrams, to high risk. These cutoffs might change with more research , but they’re a starting point.

When Is It Ordered

What is CRP Normal Range (rapid and Hs c

The CRP test may be ordered when it is suspected that you have a serious bacterial infection based on your medical history and signs and symptoms. It may be ordered, for example, when a newborn shows signs of infection or when you have symptoms of sepsis, such as:

  • Fever, chills
  • Rapid breathing
  • Rapid heart rate

It may also be ordered on a regular basis to monitor conditions such as rheumatoid arthritis and lupus and is often repeated at intervals to determine whether treatment is effective. This is particularly useful for inflammation problems since CRP levels drop as inflammation subsides.

It is also ordered and monitored after surgery to ensure that you are free of post-surgery infection.

What Does The Test Measure

A C-reactive protein test measures the amount of CRP in your blood. CRP levels can reflect the presence and severity of inflammation in your body.

CRP is a protein produced by the liver. When bacteria or other cellular invaders threaten the body, the liver releases CRP into the bloodstream to help organize the bodys defenses. This early response is called an acute phase response. It is also referred to as inflammation or an inflammatory response. The acute phase response also can occur in chronic conditions, including some autoimmune diseases.

As an early responder, CRP is technically known as a positive acute phase reactant. Its level, measured from a blood sample, gives your doctor information about the presence of inflammation and how serious it is. However, CRP levels do not tell the doctor where in your body the inflammation is located or what is causing it.

High-sensitivity CRP testing is a different form of testing that identifies very low concentrations of CRP. Although both tests measure CRP, hs-CRP is considered a separate test with distinct uses.

What Does The Test Result Mean

The level of CRP in the blood is normally low.

Increased CRP level:

  • A high or increasing amount of CRP in the blood suggests the presence of inflammation but will not identify its location or the cause.
  • Suspected bacterial infectiona high CRP level can provide confirmation that you have a serious bacterial infection.
  • Chronic inflammatory diseasehigh levels of CRP suggest a flare-up if you have a chronic inflammatory disease or that treatment has not been effective.

If the CRP level is initially elevated and drops, it means that the inflammation or infection is subsiding and/or responding to treatment.

What Elevated Crp Levels Mean

When CRP levels remain elevated for a long time, it can be an indication that chronic inflammation of the blood vessels is present.

This type of low-grade inflammation contributes to the deposit of fat and other substances in the artery walls, a condition called atherosclerosis.

This build-up can narrow the arteries that feed the heart blood, causing coronary artery disease . Over time, heart attack, stroke, or heart failure can occur.

This is true even for those with elevated CRP levels who have no obvious signs of active inflammation.

It is now well-established that inflammation is an important contributor to atherosclerosis. Elevated CRP is also firmly associated with an increased risk of CAD.

What is not known is whether CRP itself actually contributes to CAD directly.

How Much Crp Is Dangerous

Your results may vary depending on a number of factors – age, gender and health history being the most common. With that said, if your levels are above 10 mg/L it might suggest that an underlying condition or serious infection is present and some further tests may need to be carried out .

Crp Levels And The Diagnosis Of Rheumatoid Arthritis

No single test can confirm that you have RA. However, measuring levels of CRP in your blood can be part of a comprehensive diagnosis. A doctor can use your CRP levels to track the degree of inflammation over time.

If youre getting tested for RA, the doctor will likely order a standard CRP test rather than an hsCRP test.

To confirm a diagnosis of RA, the doctor will:

  • analyze results from other lab tests, such as the rheumatoid factor antibody test and cyclic citrullinated peptide antibody test
  • assess levels of morning stiffness and the amount of swelling and pain in your joints
  • document the duration of your symptoms
  • examine X-rays of the hands and feet to check for erosions or bone damage

How To Treat And Prevent Elevated Levels

C-reactive protein treatment depends on what the underlying cause of the inflammation is. The best way to naturally treat high levels is to uncover the root cause of someones inflammatory response and then make lifestyle or medication recommendations based on that finding.

The same types of healthy habits that help protect against heart disease, such as eating a balanced diet, not smoking and exercising, are also usually involved in treatment for high CRP levels are.

1. Eat An Anti-Inflammatory Diet

In order to protect against the effects of inflammation on your heart and elsewhere, its recommended that you eat a whole-foods diet such as the Mediterranean diet. This type of nutrient-dense diet includes plenty of vegetables, fruits, fresh herbs, fish, whole grains, legumes and nuts.

Eating foods high in antioxidants, such as vitamin C, A and E, plusprobiotic foods can help to support your immune system. One study found that high intake of vitamin C helped to reduce CRP levels in people with levels greater than 1 mg/L.

Its also important to address any food allergies you may be suffering from, as well as to avoid foods that trigger flair-ups if you have inflammatory bowel disease. These foods can include: gluten, dairy, caffeine, alcohol and others depending on the person.

2. Get Regular Exercise

3. Talk to Your Doctor About Your Medication Use

If an infection is the root cause of your elevated CRP, then antibiotics may be needed to help you recover.

Why Do I Need A Crp Test

You may need this test if you have symptoms of a serious bacterial infection. Symptoms include:

If you’ve already been diagnosed with an infection or have a chronic disease, this test may be used to monitor your treatment. CRP levels rise and fall depending on how much inflammation you have. If your CRP levels go down, it’s a sign that your treatment for inflammation is working.

What is C-Reactive Protein & How to Lower it? Dr.Berg

A high C-Reactive Protein level in the blood is usually a sign of inflammation or bacterial infection because CRP is one of the most sensitive acute-phase reactants.

Elevated serum concentration of CRP is an unequivocal evidence of an active tissue damage process, but it is a nonspecific test that indicates only an inflammation.

CRP can increase dramatically in case of severe trauma, bacterial infection, inflammation, surgery, or neoplastic proliferation.

A high CRP may be a sign of the following diseases:

  • Inflammatory bowel diseases .
  • Chronic inflammatory diseases .
  • Bacterial infections .

Since CRP production is a non-specific response to tissue injury, it is recommended that results of the test should be correlated with clinical findings to arrive at the final diagnosis.

A high CRP value in a blood test means:

Measuring Your C Reactive Protein Levels

Since a large number of disparate conditions, such as obesity, can increase CRP production, it cannot be used to diagnose a specific disease such as rheumatoid arthritis. CRP is merely an indicator or biomarker of a disease process that is causing cell death due to inflammation. ESR rates can be affected by obesity as well as renal failure, aging, and female sex.

Today, a high-sensitivity CRP test, usually designated as hs-CRP, measures low levels of CRP using laser nephelometry.3,4 Several studies suggest that an elevated hs-CRP is predictive of coronary heart disease.14,15 Arterial damage results from white blood cell invasion and inflammation within the walls of coronary arteries. 14 A high hs-CRP, therefore, is a rough proxy for cardiovascular risk. The widespread use and publicity surrounding the association of hs-CRP with heart disease may have obscured its diagnostic role in pain and other non-cardiac conditions.6,9-13 If a pain patient has an elevated hs-CRP, it simply means that there is an active focus of inflammationbe it in the heart, CNS, or elsewhere in the bodyand efforts must be made to eliminate it.

What Is C-Reactive Protein?

Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Bacterial infections are the most common cause, but other types of infections can also cause it.

The infections are often in the lungs, stomach, kidneys, or bladder. It’s possible for sepsis to begin with a small cut that gets infected or with an infection that develops after surgery. Sometimes, sepsis can occur in people who didn’t even know that they had an infection.

Does Aspirin Help

Aspirin does not specifically reduce levels of CRP. However, daily aspirin therapy can be used as a heart attack and stroke prevention measure, but the risks of taking aspirin for prevention may outweigh the benefits.

This may be recommended for some people with elevated CRP who are at a higher risk of heart disease or who have already experienced one of these consequences.

Those with elevated CRP may benefit from aspirin therapy more than people whose CRP levels are normal.

Aspirin therapy isn’t for everyone. Always talk to your healthcare provider before starting an aspiring regimen.
