With the aging of the U.S. population, thrombophilia—a serious and complicated disorder associated with significant morbidity and mortality that requires anticoagulant therapy—is likely to increase. In an era when so many new anticoagulants are being developed, the role of the laboratory will continue to be central to quality patient care.
This workshop will include a discussion of the advantages and disadvantages of the assays currently in use to monitor treatment. Additionally, pre- and post-analytical factors that may affect interpretations of these assays are highlighted and emphasized. You'll gain a fundamental understanding of the mechanism of action of heparin, oral anticoagulant therapy, and direct and indirect thrombin inhibitors. Plus, you'll gain the knowledge that you need to improve your practical skills and insights into this high-impact section of the laboratory.
Following this workshop, you will be able to:
- Discuss venous thromboembolism and the significance of anticoagulant therapy in treating this disorder.
- Describe the mechanism of action of heparin, oral anticoagulant therapy, and direct and indirect thrombin inhibitors.
- Explain the advantages and disadvantages of the assays currently used to monitor anticoagulant therapy.
- Discuss the variables that affect interpretation of these assays.
Debut Presentation! 6866 Solving Those Unpleasant ABO Discrepancies
8:30 am - 4:00 pm 6.0 CMLE Credits

Transfusion medicine can be a daunting laboratory area, especially if you have not had extensive practice in blood banking. Attend this workshop to gain more confidence in your blood banking skills. Designed to contribute to your professional growth through training, presentations, and discussions, this session will increase your comfort level and interest in the transfusion medicine field.
ABO discrepancies can cause delays in turnaround time, especially if they have to be sent to a reference laboratory. This workshop will equip you with the knowledge to resolve these discrepancies, which will speed up workflow, alleviate stress, and decrease costs. In addition to a greater theoretical understanding of ABO discrepancies, this session will provide you with practical experience through the discussion of case studies involving discrepancies due to single specificity antibodies, multiple antibodies, antibodies to high frequency antigens, and autoantibodies. Resolution of these discrepancies will be addressed in detail, including antibody identification, enzyme treatment, adsorptions, neutralizations and adsorption/elution studies, and the use of your facility’s resources to assist with the process.
Following this workshop, you will be able to:
- Identify ABO discrepancies by recognizing unexpected red blood cell, serum/plasma, or mixed field reactivity.
- Discuss the common lectins and the various reagents used for ABO antigen typing; appropriately use them to solve ABO discrepancies.
- Resolve problematical ABO discrepancies by performing additional testing, including extended incubation, antibody identification, enzyme treatment, and adsorption/elution studies.
7400 Molecular Methods in the Clinical Laboratory
8:30 am - 5:00 pm 7.0 CMLE Credits

Molecular diagnostics testing is rapidly having an impact on many traditional areas of the clinical laboratory. If you’re interested in updating your molecular knowledge or considering adding molecular methods to existing laboratory sections, this is the workshop for you! You’ll benefit from a comprehensive introduction to molecular diagnostic applications.
A presentation on DNA basics and the differences between molecular and traditional laboratory testing will be followed by a discussion of nucleic acid amplification and non-amplification methods, such as PCR and target capture. Using infectious disease and human genetic assays as examples, the discussion will cover the diseases that are appropriate for testing by molecular methods and the advantages and disadvantages of various assays and platforms. You’ll also be introduced to genetic abnormalities in cancer development and specialized molecular methods of detection, such as FISH and cytogenetics.
Following this workshop, you will be able to:
- Discuss genetic material (DNA and RNA) as a specific target for quantitative and qualitative identification of pathogens as well as human genetic events.
- Describe the differences between molecular and traditional laboratory testing, including quality control.
- Compare methods for infectious disease nucleic acid identification and quantification.
- Describe how and why platforms and techniques for high-throughput infectious disease applications can also be used for human genetics.
- Explain how the acquired changes in cellular DNA that promote cancer development can serve as diagnostic targets.
