Are there any laboratory findings which are typical for patients with COVID-19?
In general, laboratory findings vary. However patterns have been reported: 80% have lymphopenia, frequently platelet count is low, however usually not < 100 G/L. D-Dimer is elevated and this is also a predictor of poor outcome. Other coagulation parameters are usually normal. When coagulation parameters deter, this could point to DIC.
70% of patients have low levels of eosinophilic granulocytes. Liu et al. suggested that a rise in eosinophils may be a sign of recovery.
ALAT is typically elevated because cholangiocytes express ACE2 and are therefore also a target for SARS-CoV-2
CK may be elevated in some patients
Procalcitonin is usually not elevated, unless bacterial superinfection is present.
