IL6 and COVID-19: Exertional tests have previously been proposed and evaluated to predict severe COVID-19 pneumonia to guide early admission [2-5]. Based on their experience with 26 discharge-ready COVID-19 patients, Fuglebjerj et al. had proposed that the six-minute walk test (6MWT) could be used potentially as a tool for the assessment of patients before discharge [6]. Elevated levels of laboratory markers such as d-dimer, interleukin-6 (IL-6), and IL-10, and lower levels of peripheral lymphocytes at discharge may be associated with poor outcomes [7,8].
