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.

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.
