Evaluation of ischemia-modified albumin in the diagnosis and the clinical severity of COVID-19 in children.

Background: There is no specific biomarker used in the diagnosis of COVID-19 and predicting its clinical severity. This study aimed to investigate the utility of ischemia-modified albumin (IMA) in diagnosing and predicting clinical severity in children with COVID-19.

Methods: Between October 2020 and March 2021, 41 cases constituted the COVID-19 group and 41 cases constituted the healthy control group.

Evaluation of D-dimer levels measured by different analytical methods in COVID-19 patients.

Clinicians experience some challenges due to the lack of standardization of test, although D-dimer is a prognostic marker for COVID-19. We compared the clinical and analytical performances of D-dimer results obtained from different devices, kits and methods in patients with a diagnosis of COVID-19. Thirty-nine patients with a diagnosis of COVID-19 and 24 healthy individuals were included in the study.
