In September 1999, it proposed new rules to require careful screening of tissue donors and testing of donated tissue.
They considered the risk of infection being transmitted in blood, attitudes of potential donors in complying with the selection criteria and improvements in testing of donated blood.
They wonder if, with proper testing of donated blood, a few federal restrictions may be eased and the common weal still preserved.
The company has grown in large part through acquisitions and now has three businesses -- drugs, the testing of donated blood for viruses like H.I.V. and hepatitis C, and vaccines.
And yes, they do all the routine testing of donated blood and other tissues but they need to do so much more, not just to keep us all safe when we have blood transfusions or tissue grafts, but to develop new products and rapid testing services for the future.
About 15,000 people a year die from hepatitis C. The C.D.C. used to recommend screening only for people most likely to be infected: intravenous drug users or people who got blood transfusions before 1992 when testing of donated blood for the virus began.
She said there had been advances in the testing of donated blood which had significantly reduced the chance of errors and had reduced the size of the "window period".
Tests on donated blood, the most reliable barometer of the epidemic's spread, show that almost 2percentt of the donors were infected in the last 10 days.
The paper describes a program of mechanical testing on donated human eye bank lenses.
We suggest targeted nucleic acid amplification testing of individual donations in high-prevalence regions, a strategy that was implemented successfully for screening of WNV in the United States in 2004 (36 ); nucleic acid amplification tests of minipools of several samples of donated blood have also been proposed (36 ).
