C-Reactive Protein (CRP) Blood Test, Quantitative

What is the purpose of this test?

Order this C-Reactive Protein (CRP) Blood Test, Quantitative to measure CRP levels in the blood and helps screen for an acute infection or inflammation. CRP is a protein produced by the liver. The liver releases CRP into the bloodstream during infections or injuries to help combat bacteria or other antigens that threaten the body. This immune response is commonly referred to as inflammation or an inflammatory response. Inflammation is mainly associated with pain, redness, and swelling in the injured or affected area. Chronic conditions, including certain autoimmune disorders, may also cause inflammation. 

Therefore, individuals may order this C-Reactive Protein (CRP) Blood Test, QN to screen for or monitor conditions that cause inflammation, such as:

• Bacterial infections or sepsis
• Fungal infections
• Inflammatory bowel disease (IBD)
• Certain autoimmune disorders (lupus or rheumatoid arthritis)
• Osteomyelitis (an infection of the bone)

Note: CRP levels may be elevated by oral contraceptives, IUDs, pregnancy, or menstruation, with the lowest levels generally occurring around ovulation.

When should I order a C-Reactive Protein (CRP) Blood Test, QN?

Individuals may order this C-Reactive Protein (CRP) Blood Test, QN, if they have experienced symptoms associated with an acute infection. Common signs or symptoms of acute infection may include:

• Fever
• Chills
• Difficulty breathing or shortness of breath
• Increased heart rate or pulse
• Nausea and vomiting
• Swelling

Individuals diagnosed with an infection or a chronic condition may also use this test to monitor their treatment. CRP levels increase and decrease depending on the severity of an individual's inflammation. Therefore, decreased CRP levels may indicate that the treatment for inflammation is working.
