From Susan Lemire, can you confirm that the specimen stability for measuring fibrinogen is 24 hours? Thanks.
Hi, Susan, the attached Scientific Reports article (a Nature publication) gives specimen stability for several coagulation factors and assay results. The study seems conclusive, as the authors used a sufficient sample of 72 specimens and referenced several additional studies. We are always cautious about generalizing results from “asymptomatic patients” to those suspected of hypofibrinogenemia or dysfibrinogenemia, as abnormal fibrinogen may deteriorate at a different rate than normal fibrinogen.
