Plasma Donors in the Southwestern United States Positively Contribute to the Diverse Therapeutic Antibody Profile of Immune Globulin Products 2020-04-22 .txt text/plain 4560 208 51 In this study, source plasma from donation centers in various locations of the Southwestern quarter of the United States was surveyed for antibody titers to hepatitis A virus (HAV), measles virus (MeV), and cytomegalovirus (CMV). Safety measures implemented nearly two decades ago-collaborative, industry-wide epidemiological surveillance of the donor population, judicious selection of donors, rigorous testing of plasma by serological and molecular (e.g., nucleic acid testing) methods and validation of manufacturing methods for virus clearance capacity-provide a high degree of confidence that IG products, regardless of plasma origin, safely deliver a diverse, natural combination of human polyclonal antibodies 1,2 . The analyses of individual units originating from select pools served to demonstrate that a number of centers in the US Southwest are capable of consistently generating plasma with elevated anti-HAV Ig titers. ./cache/cord-010328-uxpedpz8.txt ./txt/cord-010328-uxpedpz8.txt
