What are the high and normal CRP readings?

Normal CRP

Levels that are lower than 5mg/L are considered normal, and are a sign that there is no direct inflammation or infection sign associated with a condition. You can also get multiple tests done to understand the progression of certain conditions.

High CRP

A high CRP reading of upwards of 10mg/L can indicate the presence of inflammation, infection, or other serious conditions. You can get further testing done or a complete blood test to understand the root of the inflammation.
