[A Family with Congenital Dysfibrinogenemia and Blood Transfusion].

Objective: To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies.

Methods: Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members.

[Gene Sequencing Analyses of 10 ABO Ambiguous Blood Group Samples].

Objective: Through analysis of ABO blood group gene typing technology, to assist in the identification of difficult clinical serological specimens.

Methods: A total of 10 forwardreverse typing ambiguous samples were collected from January 2021 to August 2021 in our hospital.ABO genotypes were analysed by gene sequencing.
