From Ann Helen: Can you trust results of PTT and factor VIII in umbilical cord blood? It seems as if it is usual to draw umbilical cord blood from newborns when the mother is a known carrier of Hemophilia A. Can you trust a high APTT and a low factor VIII in such a sample? Kind regards.

Friend and Colleague Dennis Ernst, Center for Phlebotomy Education, shared this January 8, 2021 question with George: Hello Phlebotomy Today, We’ve come across a patient whose platelets clumped in EDTA and citrate tubes. We understand that ammonium oxalate may be used to provide an accurate platelet count. Do you know of a manufacturer of these tubes? Thanks very much.
