What Does C Reactive Protein Test For

How It Is Done

C Reactive Protein Test What does it mean?

The health professional taking a sample of your blood will:

  • Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
  • Clean the needle site with alcohol.
  • Put the needle into the vein. More than one needle stick may be needed.
  • Attach a tube to the needle to fill it with blood.
  • Remove the band from your arm when enough blood is collected.
  • Put a gauze pad or cotton ball over the needle site as the needle is removed.
  • Put pressure on the site and then put on a bandage.

C Reactive Protein Treatment

The conventional C Reactive protein treatment involve prescribing the same medications that is used for lowering LDL cholesterol to reduce C reactive protein. In addition to that a healthy diet is recommended, in fact Mediterranean diet has been found effective in helping lower C reactive protein levels. Besides making dietary changes, an individual also needs to quit alcohol, smoking and exercise regularly to maintain optimum levels of C reactive protein in the body.

What Is The Conventional Treatment Of Elevated C

Conventional physicians may prescribe the same drugs used to lower LDL cholesterol to also lower levels of CRP. In addition, they will typically recommend exercise and weight loss where appropriate, since both can help lower CRP levels. In general, conventional physicians recommend the same lifestyle changes shown to reduce heart disease diet, exercise, not smoking, drinking less alcohol, following a heart-healthy diet to lower elevated C-reactive protein levels.

Can I Take The Test At Home

Options are available for at-home CRP testing. For most of these tests, you collect a blood sample at home and then mail it to a laboratory where it can be analyzed.

The blood sample for at-home CRP tests is taken from your fingertip using a very small needle called a lancet. You then apply a drop of blood to a special test paper that can be processed by the lab. Results are usually provided through a secure website or smartphone app.

At-home CRP tests can be purchased without a prescription, but it is generally best to consult with your doctor before taking an at-home CRP test. Your doctor can discuss the appropriateness of testing and help interpret any test results.

Crp And Heart Disease

CRP (C

American Heart Association in 2019 states that when considering all risk factors, people with CRP levels greater than or equal to 2 milligrams per liter may need more intense measures to prevent cardiovascular disease.

Elevated levels of CRP may have an important role in identifying people who might need closer follow-up or more intensive treatment after heart attacks or heart procedures.

CRP levels may also be useful in identifying people at risk of heart disease when cholesterol levels alone may not be helpful.

  • a diet low in nutrients and higher in fat and refined carbs
  • physical inactivity
  • overweight and obesity

A family history of heart disease can also put you at a higher risk of heart disease.

No special preparation is necessary for this test. You may eat normally on the day of, and the test can happen at any time of day.

This test is done via a blood sample, so there will be a small needle involved.

How To Get Tested

C-reactive protein testing is typically performed only after being prescribed by a doctor or other health professional.

After your doctor orders a CRP test, the blood sample can be drawn at a hospital or clinic laboratory or, if you are hospitalized, at your bedside. In some cases, the sample might be collected at your doctors office. The measurement of CRP takes place in a laboratory.

What Is The Treatment For High C

Any therapy to lower CRP levels focuses on lowering cardiovascular risk factors. Regular exercise, appropriate diet, and smoking cessation are in the forefront of cardiovascular risk prevention and reduction.

  • Cholesterol-lowering medications have been linked to lowering of CRP levels in individuals with high cholesterol. The fall of CRP levels may occur even without significant improvement in cholesterol levels.
  • The use of aspirin in healthy individuals was not shown to reduce CRP levels significantly. However, in patients with cardiovascular disease and elevated CRP, the reduction of cardiovascular risk and CRP levels was noted after aspirin use.
  • Some oral diabetes medicines, thiazolidinediones , were noted to reduce CRP levels in patients with or without type 2 diabetes. This effect was independent of their glucose-lowering effects.
  • Routine follow-up with a doctor is recommended for the proper management of conditions that are known risk factors for cardiovascular disease, such as diabetes, high blood pressure, high cholesterol, and heart disease.

What Do The Test Results Mean

C-reactive protein is measured in milligrams of CRP per liter of blood . In general, a low C-reactive protein level is better than a high one, because it indicates less inflammation in the body.

According to the Cleveland Clinic, a reading of less than 1 mg/L indicates youre at low risk of cardiovascular disease.

A reading between 1 and 2.9 mg/L means youre at intermediate risk.

A reading greater than 3 mg/L means youre at high risk of cardiovascular disease.

A reading above 10 mg/L may signal a need for further testing to determine the cause of such significant inflammation in your body. This especially high reading may indicate:

Note that CRP levels may also be elevated for those taking birth control pills. However, other markers of inflammation arent necessarily abnormal in these individuals.

Elevated CRP values in pregnancy may be a marker for complications, but more studies are necessary to fully understand the role of CRP and pregnancy.

If youre pregnant or have any other chronic infection or inflammatory disease, a CRP test is unlikely to accurately assess your risk of heart disease.

Before having a CRP test, speak to your doctor about any medical conditions that may skew the test results. Since there are other blood tests that can be performed instead, you might wish to forego a CRP test altogether.

The erythrocyte sedimentation rate is another way to measure inflammation with a sample of blood. It is a less direct measure than the CRP test. Because the CRP level responds much more quickly to changes in inflammatory activity, it can give doctors more timely information.

The ESR has a role in certain conditions where the information it provides may contribute to the decision-making process. Your physician will decide whether both tests are needed to better understand your condition. Other names for the ESR include SED rate, sedimentation rate, and Westergren sedimentation rate.

When To Treat High Crp Levels

As an additional cardiovascular risk factor, CRP levels identify those people who are more at risk for cardiovascular disease. But how useful is that information to the physician and patient?

Cholesterol-lowering medication such as a statin have been shown to lower CRP levels. A CRP test taken out of context can have questionable value. For example, if youre at low cardiovascular risk and your CRP level is borderline high, the long-term benefit of taking a statin to keep your CRP low is up for debate and further study.

C Reactive Protein Causes

The primary c reactive protein cause is the inflammation in the body. With inflammation in the body the CRP levels in the blood stream rises. This inflammation could be due to infection or trauma affecting the immune system, medical causes, lifestyle habits and genetics. The other causes of elevated CRP and other markers of inflammation are the following conditions

Normal Values For Esr And Crp

Normal results from an ESR test may show a range of range 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. The upper threshold for a normal rate value may vary among testing practices.

A person’s CRP values may vary over time. Normal results from a CRP test may show a common range of 1 mg/L to 3mg/L but are not considered high until reaching over 10 mg/L, according to the Mayo Clinic. Results for an hs-CRP test may vary from a level less than 2.0 mg/L to a level equal or greater than 2 mg/L .

Clinical Study Of Crp

In preparation for this article, I reviewed the CRP results for the last 115 patients referred to my clinic. All these patients had severe, intractable pain all were already taking opioid medications, but their pain was poorly controlled. A total of 32 patients had elevated CRP levels. Twenty-five of these 32 patients had their CRP levels return to normal with enhanced opioid therapy, while 7 patients continued to show an elevated CRP test. While a minority of patients had an elevated CRP, 27.8% is a significant percentage. Patients who were tested were already receiving pain treatment with opioids and other pharmaceutical agents, so the treatment at the time of testing undoubtedly had a positive effect on lowering the CRP. It is also possible and likely that some patients had a high CRP due to severe neuroinflammation. Two case reports illustrate how I interpreted the results.

What Is The Normal Range For A C

The general guidelines for the normal results of a CRP test vary. Usually, levels below 10 milligrams per liter are usually considered normal or free from infections. In most cases, the following values are taken into consideration for a general evaluation.Levels between 3 mg/L and 10 mg/L are considered as mildly elevated and usually result from chronic conditions such as diabetes, hypertension or lifestyle-related factors.Levels between 10 mg/L and 100 mg/L are moderately elevated. They are usually due to more significant inflammations and also indicate a higher risk from cardiac ailments. Levels above 100 mg/L are severely elevated and almost always a sign of a severe infection or an acute coronary ailment. In case a special high sensitivity CRP test is done for cardiovascular conditions, the following values are considered as benchmarks. Values less than 1 mg/L is classified as low risk. Values between 1 mg/L and 2.9 mg/L are classified as moderate risk. High risk is for results that are greater than 3 mg/L.

A high-sensitivity C-reactive protein test, which is more sensitive than a standard test, also can be used to determine the chances of developing CAD or coronary artery disease, a condition in which the arteries of your heart are narrowed. It can easily turn into a heart attack if not treated in time. Doctors believe that a high level of hs-CRP in your blood is associated with an increased risk of heart attacks. A CRP test doesnt accurately indicate the cause of inflammation. In such cases, a high hs-CRP level could mean theres inflammation caused by something besides your heart. Whether hs-CRP is the cause of high inflammation or just a marker for the same is a highly debated topic. The hs-CRP test is not prescribed for all, only for those who show a higher risk of contracting heart diseases .

The test is a simple blood test where a blood sample is drawn from your veins and sent to the laboratory for testing. The process generally includes the following steps. A healthcare practitioner disinfects the area from where the blood sample will be done. A vein near the elbow region is used in most cases. A rubber band is tied around the upper arm to increase the blood flow through the vein and make it appear prominent. A needle is inserted in the vein and the required volume of blood, which is generally around 5 ml, is drawn into an attached tube. The needle is withdrawn and the site is kept under pressure to prevent any further blood loss. It is then covered by a sterile bandage.Other than a slight prick or pain felt during the insertion of the needle, the test is simple and free from complications. In some cases finding the right vein might be difficult and multiple attempts with the needle may be necessary. There have been rare incidents of a patient feeling dizzy or light-headed after the blood is withdrawn. Any pain or bruising in the collection site is generally cured within a few days. In rare cases, excess bleeding or infection may happen which needs to be treated.

How Much Does The Test Cost

Many factors contribute to the cost of a CRP test, including the materials needed to carry out the test, the fee for the phlebotomist who draws your blood, the laboratorys fee for analyzing the sample, and the fee from your doctors office.

Your insurance coverage will determine your out-of-pocket cost. Insurance generally covers CRP testing, but depending on your policy, you might owe a deductible or a copay. If you are in doubt, check with your insurance provider.

If you are uninsured, then discuss the cost with your doctor or with the hospital or laboratory administrator. Some health care institutions have financial advocacy offices that can assist you with concerns about cost.

CRP Blood Test

A nurse or other healthcare professional will draw blood from a vein, usually on the inside of your elbow or the back of your hand.

First, they clean the skin over the vein with antiseptic. Next, they wrap an elastic band around your arm, causing your veins to bulge out slightly. The healthcare professional then inserts a small needle into the vein and collects your blood in a sterile vial.

After the healthcare professional collects your blood sample, they remove the elastic band around your arm and ask you to apply pressure to the puncture site with gauze. They may use tape or a bandage to hold the gauze in place.

Why Would I Need This Test

You might need this test if your doctor suspects that you have an infection or an illness related to inflammation or to check for infection, especially after surgery. CRP can help confirm a diagnosis and assess how well treatment is going for these kinds of illnesses.

Sometimes CRP is tested if a pregnant woman has ruptured her membranes early. CRP can indicate if there are any problems with the baby.

A special type of CRP called a high-sensitivity CRP can help determine the risk for heart disease.

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.
