High-Sensitivity C-Reactive Protein (hs-CRP) Unit Converter

High-sensitivity C-reactive protein (hs-CRP) is a blood test that measures very low levels of C-reactive protein, an acute-phase protein made by the liver in response to inflammation anywhere in the body.

While standard CRP tests detect high levels of inflammation (10-1000 mg/L), the hs-CRP test is designed to detect much smaller increases (0.3-10 mg/L). This makes it useful for identifying low-grade, chronic inflammation that may otherwise go unnoticed.

The hs-CRP test is primarily used for cardiovascular risk assessment, as low-grade inflammation plays a key role in the development and progression of atherosclerosis (plaque buildup in arteries).

CRP is produced by the liver in response to inflammatory signals, primarily the cytokine interleukin-6 (IL-6), which is released by immune cells and fat tissue during inflammation.
