A Retrospective Hospital Based Assessment of D Dimer – Prognostic Indicator for Disease Severity in Patients Hospitalized with COVID 19

ABSTRACT

Aim: To evaluate the usefulness of D-Dimer levels in blood to correlate with disease severity in COVID 19 patients. Material & Methods: The present retrospective study includes 50 patients hospitalized for COVID-19 during a period of 6 months in Government Medical College, Bettiah, Bihar, India. D-dimer evaluation was performed using an immunoturbidimetric assay on Erba Mannheim ECL 105 machine. Results: The study was conducted on 50 COVID 19 positive patients admitted to the hospital. Of the total patients, 34 were male and 16 were female. In mild cases D Dimer varies from 52 ng/ml to 192 ng/ml with mean 98.3 and median 99. In moderate cases D Dimer varies from 262 ng/ml to 998 ng/ml with mean 664.8 and median 812. Conclusion: D dimer helps in identifying severe disease and can be used as an essential biomarker in developing the management protocol for COVID 19 patients.
