How can the sensitivity of the cross-match between the recipient's serum and the
donor's cells be enhanced?
What will be an ideal response
After the initial serum:cell incubation in a cross-match, the cells can be washed (Amos modification) to remove any
unbound antibodies that have fixed complement. Antihuman globulin can then be added to enlarge any formed
immune complexes. Fresh complement is then added, and the larger immune complexes should activate it
efficiently. Detection of Class I antibodies in the presence of Class II antibodies can be enhanced by first absorbing
the recipient's serum with donor platelets that express Class I but not Class II antigens.
