Laboratory markers are also indicative of certain pathologies associated with mortality: including (i) abnormal inflammatory markers (elevated C-reactive protein, ferritin, lactate dehydrogenase and procalcitonin, and lymphopenia) [16], (ii) myocardial injury biomarkers (elevated troponin) [17,18], biomarkers of acute respiratory distress syndrome (ARDS) (hypoxaemia and hypercapnia) [19], (iii) coagulopathy markers (elevations in D-dimer, thrombocytopenia, and prolonged prothrombin time) [20,21,22]. This evidence concerns the gene F2 and acute respiratory distress syndrome.
