Hemagglutination

Test Usage

The amount of isohemagglutinin activity in the serum of the progenitor cell transplant recipient is important information in cases of major ABO incompatible progenitor cell transplantation as it may impact on engraftment. Both IgM and IgG isohemagglutinins are titrated. Anti-A or Anti-B is titered based on the donor and recipient blood types.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
