CRP Test Full Form

The full form of CRP Test is C Reactive Protein Test.


CRP Test Means

The CRP (C Reactive Protein) test is one of the most commonly done blood tests. 

  • To understand this test, it is very important to know that blood consists of two major parts: primarily plasma and cellular elements.
  • This plasma is part of the blood that is liquid, which allows the blood to flow easily. 
  • The other part of the blood consists of cells.
  • The three major cells in the blood are white blood cells (WBC), red blood cells (RBC), and platelets. 
  • And each of these types of cells carries out specific and important functions.


Interesting Facts About CRP Test

  • CRP (C Reactive Protein) is an acute-phase protein produced by the liver in response to inflammation.
  • CRP levels in the blood can rise rapidly within a few hours after the onset of inflammation or tissue damage.
  • Measuring CRP levels can help assess the presence and severity of inflammation and monitor response to treatment.


CRP Test Purpose

The purpose of the CRP (C Reactive Protein) Test is to evaluate the overall health of a patient and to detect the presence of various blood disorders like anemia, infections, inflammation, and cancer to check below purpose such as:-

  • Abnormalities in the blood
  • Evaluation of overall health
  • Rule out any disease or disorder
  • Monitoring the treatment
  • Diagnosis and treatment of various diseases

CRP Test Procedure

Here is the basic procedure of the C Reactive protein (CRP) Test.

  • A healthcare professional collects a blood sample from a vein.
  • The blood sample is sent to a laboratory for analysis.
  • In the laboratory, the CRP level in the blood is measured.
  • The results are interpreted by healthcare providers.
  • The CRP test procedure is relatively quick and straight forward.


CRP Test Result

Here is basic information regarding how to read or interpret CRP Results.

  • High CRP levels indicate inflammation or infection in the body.
  • Normal CRP levels suggest no significant inflammation or infection.
  • Low CRP levels are typically within the normal range and indicate minimal inflammation or infection.

Test Name Normal Range
CRP (C Reactive Protein) Test < 1.0 mg/L


CRP Test Intepretation

CRP Test Interpretation based on CRP Normal Range Levels.

CRP Test Result Interpretation
< 1.0 mg/L Normal CRP levels
1.0 - 3.0 mg/L Slightly elevated CRP levels
> 3.0 mg/L Elevated CRP levels, indicating inflammation or infection


CRP Test High Levels

Here is potential cause of High CRP Levels.

High CRP Levels Causes
Inflammation Infection, autoimmune diseases, injury
Tissue damage Trauma, surgery, heart attack
Chronic conditions Rheumatoid arthritis, lupus, cancer


High levels of CRP indicate inflammation or infection in the body.


What is it used for?

The CRP test may be used to find or monitor wide medical conditions that cause inflammation. These include:

  • Viral infections
  • Allergic reaction
  • Asthma, Bronchitis & Pneumonia
  • Autoimmune diseases like lupus & rheumatoid arthritis
  • Bacterial infection
  • Cancer
  • Celiac disease
  • Connective tissue disease
  • COPD (Chronic obstructive pulmonary disease)
  • Diabetes
  • Heart attack & Heart disease
  • High blood pressure
  • Inflammatory bowel disease (IBD)
  • Major trauma
  • Pancreatitis
  • Pelvic inflammatory disease (PID)
  • Systemic fungal infections
  • Vascular diseases like vasculitis & aortic aneurysm
  • Bone Infection called osteomyelitis


Specimen Requirements For CRP Test

Here are the specimen requirements for the CRP (C Reactive Protein) Test.

Specimen Blood
Volume 1 -2 ml
Container Lavender-top (EDTA) tube


CRP Test is Safe?

CRP (C Reactive Protein) Test is safe and widely used in clinical practice.

  • It is a routine blood test with minimal risk.
  • The procedure carries no significant safety concerns.


When Do You Get CRP Test Results?

CRP test results are typically available within 2 - 4 hours.

  • The exact reporting time may vary depending on the laboratory.
  • It is best to consult your healthcare provider for specific information regarding the reporting time of your CRP test.


CRP Test Limitation

CRP test results can be influenced by various factors such as infections, inflammation, and certain medications.

  • CRP levels may not always directly correlate with the severity or specific location of inflammation.
  • CRP test alone is not sufficient to diagnose a specific condition and should be interpreted in conjunction with other clinical findings


CRP Test Risk Factors

Risk factors for elevated CRP levels include obesity, smoking, chronic inflammatory conditions, and certain infections.

  • High CRP levels may indicate an increased risk of cardiovascular diseases such as heart attack or stroke.
  • Certain medications and medical conditions can affect CRP levels and should be considered when interpreting the test results.

What diseases cause high CRP levels?

Inflammation is the primary cause of high CRP levels in the blood. Therefore, conditions that are associated with inflammation can cause elevated CRP levels.

  • Some diseases that can cause high CRP levels include infections, autoimmune disorders, cancer, cardiovascular disease, and inflammatory bowel disease.
  • Infections that can cause high CRP levels include bacterial, viral, and fungal infections, such as pneumonia, meningitis, and sepsis.
  • Autoimmune disorders, such as rheumatoid arthritis and lupus, can also cause high CRP levels due to chronic inflammation.
  • High CRP levels can also be seen in cancer, as the body mounts an inflammatory response against the tumor.

What is a good CRP level?

Here is good CRP Level in table format.

CRP Level Interpretation
<1 mg/L Low risk of cardiovascular disease
1-3 mg/L Moderate risk of cardiovascular disease
>3 mg/L High risk of cardiovascular disease

What is the most common cause of high CRP?

Here is most common cause of high CRP.

  • Inflammation is the most common cause of high CRP levels.
  • Acute infections, such as bacterial and viral infections, can cause a rapid increase in CRP levels.
  • Chronic inflammation due to conditions such as autoimmune disorders, cancer, and cardiovascular disease can also cause elevated CRP levels.
  • Lifestyle factors such as smoking, poor diet, and lack of exercise can also contribute to chronic inflammation and elevated CRP levels.
  • Treating the underlying cause of inflammation is key to lowering CRP levels, and may involve lifestyle changes, medications, or other interventions depending on the specific condition.

What do high CRP levels mean?

High CRP levels indicate inflammation in the body. CRP, or C-reactive protein, is a substance produced by the liver in response to inflammation. When there is tissue damage, infection, or certain diseases, CRP levels rise. It is a marker used to monitor the severity and progress of inflammatory conditions. Elevated CRP levels alone do not provide a specific diagnosis, but they signal the presence of underlying inflammation that requires further investigation.
