You Need This Blood Test

From eNewsletter 7/21/2025

DID YOU KNOW that there is a critical reason why we track your high-sensitivity C-reactive protein levels (hsCRP) year in and year out? It gives us a idea of your level of inflammation, specifically in the heart region. A new study from The Lancet eBiomedicine echos this.

After following almost 6,000 patients for over 20 years, those with the consistently highest serum hsCRP levels had the highest number of cardiovascular events and all-cause mortality, independent of any other form of testing.

There are two instances where hsCRP can be elevated but not necessarily tied to heart risk: acute exercise performed soon before your blood draw and acute infection. This is why it is important to continually get hsCRP at every blood test, so we can get a large sample size.
