A literature review reported that common COVID-19 laboratory findings include eosinopenia (frequency noted in COVID-19 patients: 78.8%), lymphopenia (68.7%), elevated AST (63.4%) levels, elevated CRP (60.7%) levels, elevated PT (58.0%), elevated lactate dehydrogenase (LDH) (47.2%) levels, elevated D-dimer (46.4%) levels, thrombocytopenia (36.2%), elevated ALT (21.3%) levels, and elevated high-sensitivity troponin (12.5%) levels [20]. Here, CRP is linked to lymphopenia.
