CRP and COVID-19: Compared with moderate COVID-19 patients, severe COVID-19 patients frequently had hypoalbuminemia and relatively high levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), high-sensitivity C-reactive protein (hsCRP), ferritin, D-dimer and procalcitonin in the blood, suggestive of a significantly increased systemic inflammation (Chen G. et al., 2020).
