Significance of Laboratory Markers in Predicting the Severity of COVID-19 in the Central Reserve Police Force Front-line Workers with a Review of Literature

COVID-19 disease has variable clinical presentations, ranging from asymptomatic to mild symptoms to severe manifestation with pneumonia, acute respiratory distress syndrome, septic shock, disseminated intravascular coagulation, and/or multiple organ failure. The real-time reverse transcription-polymerase chain reaction is gold standard test for severe acute respiratory syndrome-coronavirus-2 detection. In the present study, we aimed to predict the significance of various hematological and biochemical markers for early identification of complications and assessing the severity of the disease. A total of cases were divided into two study groups, namely, severe and nonsevere based on clinical presentation. Out of 210 cases, 186 (88.5%) cases were nonsevere and 24 (11.5%) cases were severe. Among various hematological and biochemical markers studied, hemoglobin, total leukocyte count, neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, albumin, lactate dehydrogenase, C-reactive protein, ferritin, D-dimer, and interleukin-6 are found to have P < 0.05 and significantly correlated with the severity of disease.
