ALB and cancer: The elevated blood D-dimer level and low serum albumin have also been validated to predict the PE recurrence in cancer patients [20-23]. The results of the current study have shown that both elevated D-dimer as well as low serum albumin can serve as satisfactory predictors of recurrence of PE. The association between low serum albumin level and thrombosis was explained by the fact that albumin is known to have both heparin-like antithrombotic activity as well as being an inhibitor of platelet aggregation; loss of these functions underlies the increased tendency to thrombosis [24].
