Two further examples of IgG thimerosal-dependent antibodies and their serological characteristics

Two further examples of IgG thimerosal-dependent antibodies have been found by routine immunohematological tests carried out in our laboratory. Both antibodies fixed the complement and had no apparent blood group specificity. Their reactivity was inhibited by adding thimerosal to the serum prior to the addition of red blood cells. If cross matching is performed accordingly, thimerosal-dependent antibodies should not any longer represent a blood bank problem.
