Program Description
This program is intended as an introduction and/or refresher on “high titer low avidity” (HTLA) reactivity that often present a challenge to identify and work around. Within the lecture portion of the program, learners will receive background on the blood group antigens associated with these tricky reactivity patterns. Learners will also be presented with methods and techniques used in the laboratory to identify these antibodies. Case studies will conclude the session to provide examples of how these antibodies may present within a patient case.

Learning Objectives
After participating in this educational activity, participants should be able to:

Describe the concept of “high titer low avidity antibodies” (HTLA) and associate appropriate blood group antigens with this type of reactivity. (Chido/Rodgers blood group, Knops blood group, Cost collection, JMH, Sda, Bgs)
Discuss the serologic characteristics, clinical significance, and therapeutic implications of the antibodies directed toward the antigens listed above.
Discuss the laboratory methods used to differentiate these serologically difficult antibodies including titration, urine and plasma neutralization, and enzyme sensitivity.
Identify reactivity patterns associated with these blood group antigens within the context of a case study.

How to Claim Continuing Education Credit

Single Viewers: if you registered as a single viewer, complete the evaluation found on the "CE Information" tab after watching the video. By submitting the evaluation, you are attesting to watching the presentation in its entirety.
Group Viewers: This is applicable for groups/facilities that purchased Group Viewing access for this program (registration will be verified prior to processing a group viewing attendance log). Group Viewing Coordinators should submit the attendance log to eLearning@aabb.org within 72 hours of the completion/viewing date. Once AABB receives an attendance log, each participant on the attendance log will be granted access as a single viewer to this program and will be required to complete the evaluation in order to claim continuing education credit. Each participant will be required to have an AABB account in order to access this program/platform. If a participant does not have an account, he/she can create one using the same email address provided on the attendance log.
