CRP and COVID-19: In addition, serum albumin concentration showed linear correlation with highest hs-CRP (r = −0.306, p < 0.001), highest procalcitonin (r = −0.286, p < 0.001), and lowest lymphocyte count (r = 0.264, p < 0.001), indicating a clear link with the hyperinflammatory response in COVID-19, especially in the setting of chronic inflammation in metabolic disease.
