Mindray's Biochemistry D-dimer Solution for COVID-19

Mindray 2020-12-31

COVID-19 caused by SARS-CoV-2 infection, is a contagious disease leading to the ongoing pandemic. D-dimer testing, a sensitive parameter to investigate hemostasis, could be helpful to rapidly identify COVID-19 patients with severe illness, pulmonary complications, and risk of thromboembolism. A recent meta-analysis has shown that patients with severe COVID-19 have higher D-dimer concentrations[1]. The risk stratification assisted by D-dimer testing and early treatment might reduce COVID-19-related morbidityand mortality[2,3]. As a sensitive monitoring index, D-dimer could provide valuable clinical information in the management and prognosis prediction of COVID-19 patients.

Mindray's Biochemistry D-dimer Solution

Mindray biochemistry D-Dimer assay with particle-enhanced immunoturbidimetric method can give quantitative determination of cross-linked fibrin degradation products (D-dimers).

Key benefits of Mindray D-dimer tests:

Ready to use reagent: fully automated processing without manual working solution preparation

Stable reagents: 4 weeks on-board stability at 2–8°C

Wide linearity range (0.5~48 μg/mL): reduce sample dilution and improve efficiency

High precision:
