Laboratory abnormalities in patients with COVID-2019 infection

The currently available data suggests that many laboratory parameters are deranged in patients with COVID-19, and some of these may also be considered significant predictors of adverse clinical outcomes. The most frequent abnormalities were lymphopenia (35–75% of cases), increased values of CRP (75–93% of cases), LDH (27–92% of cases), ESR (up to 85% of cases) and D-dimer (36–43% of cases), as well as low concentrations of serum albumin (50–98% of cases) and hemoglobin (41–50%). Many laboratory abnormalities were instead predictive of adverse outcome, including increased white blood cell count, increased neutrophil count, decreased lymphocyte count, decreased albumin, increased LDH, ALT, AST, bilirubin, creatinine, cardiac troponins, D-dimer, prothrombin time, procalcitonin and CRP values
