OBJECTIVES/HYPOTHESIS Whereas mechanical (traumatic) causes of laryngotracheal stenosis (LTS) are identified based on history, autoimmune laryngotracheal stenosis (aLTS) and idiopathic laryngotracheal stenosis (iLTS) are often more difficult to differentiate. The objective of this study was to evaluate serologic testing in a large cohort of nonmechanical LTS patients to determine which tests, i...

Abstract In April 2020, the National Cancer Institute (NCI) and Frederick Laboratory for Research (FNLCR) built Serological Sciences Network(SeroNet) on foundation of HPV Serology program to develop serology technologies better understand immune response infection vaccines. SeroNet members (steering committee, investigators, working groups) are funded by NCI (through The Paycheck Protection Pro...

Pre-transfusion testing is performed to ensure the normal survival of transfused red blood cell products i.e. to prevent hemolytic transfusion reaction via immune-mediated mechanism [1]. The serological part of pre-transfusion testing includes; ABO group and Rh (D) type, antibody screening and crossmatching [2]. Antibody screening is included to detect unexpected antibody and was first introduc...
