Also, at a cutoff value of 72 ng/ml, NGAL predicted severe COVID-19 with a sensitivity rate of 57% and a specificity rate of 84%. Serum NGAL level (adjusted hazard ratio [aHR]=1.020, 95% confidence interval [CI]= [1.006-1.035], p=0.007), and D-dimer level (aHR=2.371, 95% CI= [1.085-5.181], p=0.030) were the variables that were revealed to be significantly associated with the disease severity.Conclusion: We demonstrated that NGAL was highly associated with COVID-19 severity. We consider that NGAL might be a useful biomarker to diagnose the disease severity in patients with COVID-19. ER -
