question: What laboratory abnormalities are commonly seen in patients with COVID-19?
answer: Common laboratory abnormalities among patients with COVID-19 include:
  
  1. Elevated inflammatory markers (e.g., ferritin, C-reactive protein, and erythrocyte sedimentation rate).
  2. Elevated aminotransaminase levels (i.e., AST, ALT).
  3. Elevated lactate dehydrogenase (LDH) levels.
  4. Lymphopenia, leucocytosis.
  
  Abnormalities in coagulation testing (e.g., increased D-Dimers, decreased platelets), elevated procalcitonin levels, and elevated troponin levels have also been reported. The degree of these abnormalities tends to correlate with disease severity.
