CRP

When you visit a doctor with an infection or inflammation, they may order a C-reactive protein (CRP) test. It is a simple blood test that helps determine how much inflammation is present in your body. High CRP levels often indicate an infection or another inflammatory condition.

In this article, we’ll explore:

  1. What CRP is and why it matter?
  2. Common infections linked to high CRP
  3. Symptoms to watch for
  4. How to manage infections and reduce inflammation?
  5. When to seek medical help?

What is CRP?

CRP is a substance produced by your liver in response to inflammation. When your body fights an infection, injury, or disease, CRP levels rise.

Doctors use this test to:

  • Detect bacterial or viral infections
  • Monitor chronic inflammatory conditions like arthritis
  • Assess recovery after surgery or treatment

A normal CRP level is usually below 10 mg/L. Higher levels suggest an active infection or inflammation.

Common Infections Linked to High CRP

High CRP levels often point to infections such as:

1. Bacterial Infections

  • Pneumonia lung infection
  • Urinary Tract Infections
  • Sepsis- a severe, life-threatening infection
  • Skin infections like cellulitis, abscesses

2. Viral Infections

  • Influenza 
  • COVID-19
  • Hepatitis

3. Fungal or Parasitic Infections

  • Tuberculosis (TB)
  • Malaria

CRP levels are usually much higher in bacterial infections compared to viral ones. Doctors may use this to decide whether antibiotics are needed.
