Answer

Lymphopenia (83%) is the most common laboratory finding in hospitalized patients with coronavirus disease 2019 (COVID-19). [1]

Findings that may be associated with more illness severity include the following [1] :

  • Lymphopenia

  • Neutrophilia

  • Elevated levels of serum alanine aminotransferase and aspartate aminotransferase

  • Elevated lactate dehydrogenase

  • High C-reactive protein (CRP) level

  • High ferritin levels

Elevated D-dimer and lymphopenia have been associated with mortality.

Although procalcitonin is typically normal on admission, levels may increase among those admitted to the intensive care unit (ICU).

Critically ill patients generally have high plasma levels of inflammatory makers, suggesting potential immune dysregulation.
