From “Kaarin,” We are wondering what other labs are using for a positive (deficient) control for factor XIII assay by the clot-lysis methodology. Deficient plasma?
Hello, Kaarin, thanks for your question, which will attract some responses soon. A quick check of major plasma control distributors shows that only Hyphen BioMed, distributed in North America by Aniara, provides a factor XIII deficient plasma. We’ve also had some past discussion on factor XIII assays, linked here. I wonder how many of us continue to use urea solubility as our primary assay?
