(en) DEAR EDITOR, We read with interest the letter by Nielsen N.D. and coll. [1] dealing with D-dimer and fibrinolysis in COVID-19 patients. The authors discussed the apparent discrepancy between increased D-dimer in and decreased fibrinolysis potential of the blood of COVID-19 patients. They proposed an extravascular origin for the observed increase in D-dimer plasma levels, which could solve the so-called paradox. This interesting discussion provides us with an opportunity to highlight some key points about D-dimer and the methods used to assess fibrinolysis. [...]
