Clinically, CRP concentrations are used for the diagnosis and monitoring of inflammatory processes (Pepys, 2003) in rheumatologic disease (Rhodes et al., 2010; Ammitzbøll et al., 2014; Wielińska et al., 2020), ankylosing spondylitis (Xu, Jiang & Zhang, 2020), inflammatory bowel disease (Vatay et al., 2003), pancreatitis (Windgassen et al., 2011), cardiovascular disease (Hage & Szalai, 2007; Ni et al., 2020), cancer (Windgassen et al., 2011), and infections (Pepys, 2003).
