A retrospective analysis of a cytotoxic T-lymphocytes antigen-4 antibody that can increase T cell activity and proliferation demonstrated that increased LDH levels indicate a poor outcome[8] According to the autopsy results of patients who died due to COVID-19, T cells play a vital role in this disease.[9] Serum albumin has been used as a prognostic factor for infections because it potentially decreases with infection exacerbation; it is low in patients with sepsis and has been reported to be a crucial factor affecting mortality and prognosis.[10–12]. The gene discussed is ALB; the disease is COVID-19.
