AB We have decided that it is essential to establish a process to protect
patients receiving concentrated red blood cells (CGR) from a residual
risk of contamination by the HIV virus or by the hepatitis C virus.
Viral inactivation techniques of labile blood products are not presently
in use, only safety measures obtained by quarantine allow a reduction of
this risk to a value approaching 0. We have developed, from known
deep-freeze methods of red blood corpuscles, a process to place the
samples of concentrated red blood cells in quarantine by means of
deep-freezing. We have modified and automated the deep-freezing, thawing
and washing manipulations of the red blood corpuscles in order to obtain
a final product which is standardized in quantity and quality. The
result of our work will show: That all the means employed are not a
source of contamination of the end product. That the procedures employed
may be easily adapted to all Blood Transfusion Centers. That the
end-product may be used after 21 days of conservation. That the extra
cost entailed by this procedure is realistic.
