From: Brancaccio Mauro, ICD-Partners, Italy. Is it possible and correct to do the PT on the sangueblood?
Hello, Bancaccio Mauro. If I translate correctly, I will take sangueblood to mean whole blood (with thanks to Dave McGlasson for his assistance). Yes, the PT has been established as a whole blood assay using point of care instrumentation. Many POC instruments apply a ratio computation to modify whole blood results so they correlate with plasma-based results. I hope this is the answer you are looking for, and thank you for contacting Fritsma Factor.
