We have observed CT severity as the best visual marker of severity of COVID-19 pneumonia which can be correlated with inflammatory markers like ferritin, CRP, IL-6 LDH, D-dimer and lymphopenia, and lymphocyte platelet ratio, and it will help in triaging cases in casualty and help in targeting interventions in indoor units accordingly to have successful treatment outcome. This evidence concerns the gene CRP and lymphopenia.
