Lymphopenia, either isolated or in conjunction with an elevated absolute neutrophil count (ANC), increased lactate dehydrogenase, liver function tests, and troponins, and high levels of C-reactive protein (CRP), IL-6, IL-2 receptor, D-dimer, and ferritin are common following a symptomatic acute COVID-19 infection (39, 40). This evidence concerns the gene CRP and lymphopenia.
