A normal C-reactive protein (CRP) level is generally considered to be between 0 to 3 milligrams per liter (mg/L) of blood.
Here's a more detailed breakdown:
- Normal CRP Level: Less than 3 mg/L. This typically indicates a low level of inflammation in the body. A more specific normal range is often cited as less than 0.9 mg/dL.
- Elevated CRP Level: A CRP level above 3 mg/L suggests that there is inflammation present. The higher the CRP level, the greater the degree of inflammation. The cause of the inflammation needs to be determined by a healthcare professional.
While there isn't a concept of a "low" CRP level causing concern, an elevated CRP level is a sign that something is causing inflammation in the body. This could be due to various factors, including:
- Infections (bacterial, viral, or fungal)
- Inflammatory conditions (such as arthritis or lupus)
- Tissue injury
- Certain cancers
- Heart disease
It is important to consult with a healthcare provider to interpret your CRP level in the context of your overall health and medical history. They can order further testing to determine the underlying cause of elevated CRP levels.
