HT2-B27 Results Entry Guide


NEW for laboratories that do not perform crossmatching!

In the past, if your laboratory did not perform crossmatching and you wanted to order the discounted AC module (serum samples only), both the AC and AT modules had to be selected in your PT order. This year, laboratories that want the discounted module containing serum samples only, do not have to select two modules in their PT order. They only need to select the new AO (Antibody Only) discounted module since the AO module replaces the prior AC/AT ordering format.



Subscribers from each survey region/ group will have the opportunity to utilize their own AC survey antibody results in conjunction with donor cell typing from another region/group (assigned by the PT Committee) to perform virtual crossmatch assessments that can be compared to actual crossmatch results from AC survey responses. Look for updated information in AC survey instructions, ASHI Insights and ASHI Quarterly.
