CEU CASE STUDY: RESOLUTION OF A POSITIVE ANTIBODY SCREEN WITH A POSITIVE AUTOCONTROL

This course is designed to guide the learner through a commonly-encountered serological challenge. Unexpected pre-transfusion test results, including a positive three cell screen and a positive autocontrol require investigation. Resolution and transfusion considerations are discussed.

TARGET AUDIENCE: Technologists, Technicians, Laboratory Managers

LEVEL: Basic

SUCCESS TM CREDITS: 1 CEU

Enter Course

LEARNING OBJECTIVES

At the conclusion of this course, participants should be able to:

1. Correlate serologic findings between the autocontrol and DAT

2. Appropriately utilize EDTA Glycine Acid reagent

3. Employ techniques for excluding alloantibodies when an autoantibody is present

4. Identify antibody specificities that may be naturally-occurring

5. Recognize special transfusion considerations for patients with a positive autologous control


LEARNING TASKS

To receive CEU credit for this course, participants must:

1. Review the presentation " Resolution of a Positive Antibody Screen with a Positive Autologous Control" or read the PowerPoint slides and accompanying notes available as a printable Adobe Reader® file.
