Some laboratory features associated with severe COVID-19 had been reported, including elevation in D-dimer, C-reactive protein, lactate dehydrogenase, troponin, ferritin, creatine-phospho-kinase, and decrease in absolute lymphocyte count.[22–27] However in our study, the patients whose absolute lymphocyte count was lower than 800 per microliter did not had the higher odds of death. This evidence concerns the gene CRP and COVID-19.
