IL6 and COVID-19: Consistent with these findings, our study observed correlations between elevated ALT and GGT, LDH, ferritin, and troponin in non-COVID-19 patients and with GGT, LDH, ferritin, CRP, and platelets in COVID-19 patients, supporting the link between liver damage, coagulopathy, and endotheliopathy, but not IL-6.
