Why D-Dimer test is Important in Severe COVID-19 Infection


Severe COVID-19 infection is associated with high morbidity and mortality with 50% of the deaths determined to be due to coagulopathy1. Studies have revealed that patients with serious infection are more likely to have COVID-19 associated coagulopathy than patients with mild infection, and those who die from COVID-19 are more likely to have met the International Society on Thrombosis and Haemostasis, criteria for disseminated intravascular coagulation compared to survivors. Elevated D-dimer at admission and markedly increasing D-dimer levels (3- to 4-fold) over time are associated with high mortality, likely reflecting coagulation activation from infection/sepsis, cytokine storm and impending organ failure2. Based on these studies and recently published guidelines from the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC), strongly advocate for D-Dimer testing in patients with COVID-193.

Because of the increasing number of patients with severe COVID-19 infection, labs are experiencing a spike in D-Dimer test demand. The need for improved turnaround time and for a more reliable supply chain has left many labs reevaluating their current D? Dimer testing strategy.
