What Does The Test Measure

The 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 aninflammatory 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 Else Do I Need To Know Before I Appear For A C

The CRP test is simple in nature and the following points will assist in getting to know the test and associated results better. A high level of CRP does not necessarily mean that you are suffering from a cardiac ailment. For any patient who is pregnant or has any other chronic infection or inflammatory disease, the CRP test alone is not sufficient to assess the risk of heart disease. The CRP level is termed as a biomarker and is not a precise indicator of any health problem. In case you have higher levels of the protein, the doctor may suggest lifestyle and dietary changes as a part of the treatment plan.Routine follow-up with the doctor is often necessary if any high-risk ailments like heart disease, diabetes, and others are established.

Why Do Healthcare Providers Perform Crp Tests

Healthcare providers typically order a C-reactive protein test to help diagnose or rule out certain conditions, including:

  • Severe bacterial infections, such as .
  • Fungal infections.

Your provider may also use CRP tests to monitor your treatment if youve already been diagnosed with an infection or a chronic inflammatory condition.

CRP levels increase and decrease depending on how much inflammation your body has. If your CRP levels go down, it’s a sign that your treatment for the inflammation is working.

Why Do I Need A Crp Test


You may need this test if you have symptoms of a bacterial infection, such as:

You may also need a CRP test if your provider thinks you may have a chronic condition that causes inflammation. The symptoms will depend on the condition.

If you’ve already been diagnosed with an infection or a chronic disease that causes inflammation, you may need this test to monitor your condition and treatment. CRP levels rise and fall depending on how much inflammation is in your body. If your CRP levels fall, it’s a sign that your treatment for inflammation is working or you’re healing on your own.

How Does A Crp Test Work

CRP blood work is fairly standard in terms of how it is administered. A small amount of blood is taken and placed into a vial or safe testing kit. The blood is then sent to a lab to be analyzed. The test can be performed at home or in a clinical setting. The test results measure the amount of CRP protein within the blood.

Depending on the amount of CRP in the blood, it could be a sign of serious infection, chronic disease, or another condition.

The ranges of CRP levels in the blood1 are as follows:

What Abnormal Results Mean

It is unclear if a minor rise of 0.3 to 1 mg/dL in CRP levels is a cause for concern. The hs-CRP is more precise and may be used to further understand these results.

  • CRP levels from 1 mg/dL to 10 mg/dL are thought to be a moderate increase.
  • CRP Levels greater than 10 mg/dL are considered a marked increase.

A positive test means you have inflammation in the body. The cause of a high CRP cannot always be determined. Some include:

What Are The Complications Of Osteomyelitis

c-reactive protein test explained | CRP test | Inflammation marker test | Blood CRP levels

Complications of osteomyelitis include:

  • Abscesses: Infection may spread to muscles and soft tissue, causing abscesses. These pockets of pus can seep through your skin. People with chronic osteomyelitis are more likely to have recurring abscesses. Treatment to drain these abscesses may slightly increase the risk of skin cancer.
  • Bone death: Also called osteonecrosis, bone death can occur if swelling from the infection cuts off blood flow to your bone. Very rarely, this may lead to loss of a limb or amputation.
  • Stunted growth: Osteomyelitis in a growing child may stunt bone growth.

What Do My Test Results Mean

Test results may vary depending on your age, gender, health history, and other things. Your test results may be different depending on the lab used. They may not mean you have a problem. Ask your healthcare provider what your test results mean for you.

The normal range for this test depends on the lab and the procedure used in the lab. Generally, a CRP level under 10 milligrams per liter is considered normal. If the level of CRP in your blood is higher than that, it may mean your body is having an inflammatory reaction to something. More tests will be needed to figure out what’s causing the inflammation.

How Much Does The Test Cost

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

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, the hospital, or laboratory administrator. Some health care institutions have financial advocacy offices that can assist you with concerns about cost. Typically, you can use your FSA or HSA to pay for testing.

What Does An Elevated C

Elevation of C-reactive protein indicates acute phase response or active disease in chronic inflammatory disorders. CRP is a more sensitive early indicator of an acute phase response than the ESR . C-reactive protein also returns towards normal more rapidly with improvement or resolution of the disease process.

C-reactive protein elevations are nonspecific and may be useful for the detection of systemic inflammatory processes to assess treatment of bacterial infections with antibiotics to detect intrauterine infections with concomitant premature rupture of membranes to differentiate between active and inactive forms of disease with concurrent infection, e.g., in patients suffering from systemic lupus erythematosus or ulcerative colitis to therapeutically monitor rheumatic disease and assess anti-inflammatory therapy to determine the presence of postoperative complications at an early stage, such as infected wounds, thrombosis, and pneumonia and to distinguish between infection and bone marrow rejection. Postoperative monitoring of CRP levels of patients can aid in the recognition of unexpected complications .

However, the C-reactive protein test is less sensitive than the ESR for some disorders, for example, ulcerative colitis and SLE .

Elevated of C-reactive protein test result means you have inflammation in the body. This may be due to a variety of conditions, including:

  • Rheumatic fever

Treating And Preventing Elevated C

Pin on Healthcare

By Jillian Levy, CHHC

C-reactive protein levels increase and decrease depending on how much inflammation youre experiencing at any given time. Inflammation is defined as Redness, swelling, pain, and/or a feeling of heat in an area of the body. This is a protective reaction to injury, disease, or irritation of the tissues.

When you arent sick or injured, its normal for C-reactive protein levels to be low. But when something happens to signal to the body that it needs to be healed, levels rise to make this happen. Once you start to recover and symptoms subside, levels will fall and should return to normal.

This is why doctors use CRP tests to determine if a patients treatment plan is working, in addition to assessing if he/she is at risk for problems related to chronic inflammation , including heart disease.

What Are The Treatments For Crohn’s Disease

There is no cure for Crohn’s disease, but treatments can decrease the inflammation in your intestines, relieve symptoms, and prevent complications. Treatments include medicines, bowel rest, and surgery. No single treatment works for everyone. You and your health care provider can work together to figure out which treatment is best for you:

  • Medicines for Crohn’s include various medicines that decrease the inflammation. Some of these medicines do this by reducing the activity of your immune system. Medicines can also help with symptoms or complications, such as nonsteroidal anti-inflammatory drugs and anti-diarrheal medicines. If your Crohn’s causes an infection, you may need antibiotics.
  • Bowel rest involves drinking only certain liquids or not eating or drinking anything. This allows your intestines to rest. You may need to do this if your Crohn’s disease symptoms are severe. You get your nutrients through drinking a liquid, a feeding tube, or an intravenous tube. You may need to do bowel rest in the hospital, or you may be able to do it at home. It will last for a few days or up to several weeks.
  • Surgery can treat complications and reduce symptoms when other treatments are not helping enough. The surgery will involve removing a damaged part of your digestive tract to treat

How Is Crohn’s Disease Diagnosed

Your health care provider may use many tools to make a diagnosis:

  • A medical history, which includes asking about your symptoms
  • A family history
  • Checking for bloating in your abdomen
  • Listening to sounds within your abdomen using a stethoscope
  • Tapping on your abdomen to check for tenderness and pain and to see if your liver or spleen is abnormal or enlarged
  • Various tests, including
  • An upper GI endoscopy, a procedure in which your provider uses a scope to look inside your mouth, esophagus, stomach, and small intestine
  • Diagnostic imaging tests, such as a CT scan or an upper GI series. An upper GI series uses a special liquid called barium and x-rays. Drinking the barium will make your upper GI tract more visible on an x-ray.

    How Is Sepsis Diagnosed

    Your health care provider may use many tools to make a diagnosis:

    • A medical history, which includes asking about your symptoms
    • A physical exam, including checking vital signs
    • Lab tests that check for signs of infection or organ damage
    • Imaging tests such as an x-ray or a CT scan to find the location of the infection

    Many of the signs and symptoms of sepsis can also be caused by other medical conditions. This may make sepsis hard to diagnose in its early stages.

    What Is The Most Likely Cause

    C-Reactive Protein (CRP) Blood Test in 3 Minutes

    Chronically elevated CRP levels often signal RA or infectious arthritis, which occurs when a joint becomes infected.

    Significantly elevated CRP levels tend to occur with severe infections, such as bacterial or fungal infections. Bacterial infection is responsible for about of the cases involving CRP levels higher than 50 mg/l.

    Sometimes, higher levels also occur with certain cancers and other conditions that can cause significant inflammation.

    What Are The Risk Factors For High Levels Of C

    Heart disease has an inflammatory component, which may be linked to high C-reactive protein levels. However, based on the current available data it cannot be considered an independent risk factor for cardiovascular disease.

    Based on the review of the published data, the CDC and the American Heart Association have recommended the following guidelines for assessment of cardiovascular disease risk:

    • CRP levels of 1 mg per liter or lower are considered low risk for cardiovascular disease.
    • CRP levels of 1-3 mg per liter are considered moderate risk for cardiovascular disease.
    • CRP levels greater than 3 mg per liter are considered high risk for cardiovascular disease.
    • CRP levels greater than 10 mg per liter may suggest an acute coronary process, such as heart attack .

    The known risk factors for cardiovascular disease are:

    This may be possibly related to ongoing inflammatory atherosclerosis in these individuals because of their risk factors.

    Despite these associations, research has not clearly and consistently established c-reactive protein as an independent risk factor for cardiovascular disease, as the data seem to be inconsistent from different studies. It has been proposed that elevated c-reactive protein is an independent predictor of atherosclerosis among healthy men and women.

    What Are The Treatments For Sepsis

    It is very important to get treatment right away. Treatment usually includes:

    • Maintaining blood flow to organs. This may involve getting oxygen and intravenous fluids.
    • Treating the source of the infection
    • If needed, medicines to increase blood pressure

    In serious cases, you might need kidney dialysis or a breathing tube. Some people need surgery to remove tissue damaged by the infection.

    Who Is At Risk For Sepsis

    Anyone with an infection could get sepsis. But certain people are at higher risk:

    • Adults 65 or older
    • Fever, shivering, or feeling very cold
    • Clammy or sweaty skin

    It’s important to get medical care right away if you think you might have sepsis or if your infection is not getting better or is getting worse.

    How Does Crp Relate To Cardiovascular Risk


    Your level of C-reactive protein can be an indicator of how at risk you are for developing cardiovascular problems. This is because the development of atherosclerosis is associated with inflammation within the vessel walls. The result is higher levels of CRP in patients with atherosclerosis than in those without atherosclerosis.

    The value of knowing CRP levels depends on whether you fall into one of three cardiovascular risk groups:

    • Low risk because of low cholesterol levels and little history of risk factors that is, no diabetes, high blood pressure, or smoking, and no family history of heart attacks at an early age. Even a higher level of CRP will probably not put you at a level of risk that requires than lifestyle changes.
    • Intermediate risk helpful to know CRP level, because it can provide missing piece of information for physician deciding next step in treatment
    • High risk not essential to know your CRP, because you should already be combining aggressive treatment with lifestyle changes to lower your risk

    Who Should Get A Crp Test

    If your doctor suspects you might have an inflammatory disorder like arthritis, cancer, an infection, etc., they may order a C-reactive protein test. This test can show theres a high level of inflammation, but it cannot show where the inflammation is located or what might be causing it. If you have been previously diagnosed with an inflammatory issue, your doctor may also order this test occasionally to see how your treatment is working and if the issue is being properly managed.

    Its important to note that the high-sensitivity C-reactive protein test is a slightly different test than a regular C-reaction protein test. This test typically predicts heart disease and strokes. And while the regular C-reactive test can help to uncover different diseases that cause inflammation by measuring high levels of protein, the hs-CRP test measures a lower amount of protein, which can signal the risk of heart disease and stroke.

    Your doctor may order an HS-CRP if theyre focusing on cardiovascular issues.

    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.
