A case of falsely elevated D-dimer result

Abstract

Heterophile antibodies can cause interferences in immunometric assays. While many tests are shown to be affected by interference from heterophilic antibodies, the D-dimer test has rarely been reported to be affected. With this case, we report an elevated D-dimer measurement which was not compatible with the clinical presentation.
