hsCRP

High-sensitivity C-reactive protein (hsCRP) is a refined biomarker that measures low levels of C-reactive protein, an acute-phase protein produced by the liver in response to inflammation. It is part of the body's innate immune response and is regulated by cytokines such as interleukin-6. Clinically, hsCRP is a valuable tool for assessing cardiovascular risk, particularly in individuals without known atherosclerotic cardiovascular disease (ASCVD). Elevated hsCRP levels are associated with an increased risk of major adverse cardiovascular events (MACE), cardiovascular death, and all-cause mortality. Researchers have found that hsCRP levels >3 mg/L significantly heighten these risks, making it a critical marker in primary prevention strategies. In the context of athletic performance and biohacking, hsCRP serves as an indicator of systemic inflammation, which can affect recovery and performance. Athletes and biohackers may monitor hsCRP to optimize training regimens and recovery protocols, aiming for lower levels to minimize inflammation-related impairments. However, interpreting hsCRP levels requires consideration of various confounders such as recent infections, injuries, or chronic inflammatory conditions. Time-of-day and fasting status do not significantly affect hsCRP levels, but acute physical exertion and certain medications can interfere with results. Therefore, consistent testing conditions are recommended for accurate longitudinal monitoring.
