Meet the One Lambda Brand: Delivering Personalized Transplant Care Through Precision

For over 25 years, One Lambda brand assays have been the gold standard for the detection of donor-specific antibodies. As the trusted partner of HLA labs around the world, we provide essential assays to deliver reliable and actionable data for the screening and monitoring of transplant patients. In this short video, discover how we are working to help deliver personalized care to every transplant patient.

One Lambda is dedicated to enabling more personalized treatment in the transplant clinic in order to help our customers improve the lives of patients around the world.

Our comprehensive product portfolio includes a broad range of Antibody Detection assays, HLA Typing products, and post-transplant monitoring solutions, including MMDx® Heart and MMDx® Kidney that are biopsy-based Laboratory Developed Tests that measure gene expression profiling and provide risk assessment for rejection and injury in transplant organs.

The MMDx Heart & Kidney tests can help stratify the risk for conditions like T-cell mediated rejection (TCMR), antibody-mediated rejection (ABMR), acute and chronic injury, atrophy fibrosis, and arterial hyalinosis.

Value of MMDx in Diagnostic Uncertainty in Patients with Heart Transplantation: A Case-Based Presentation

Friday, October 14, 2022 | 10:00 AM PST / 1:00 PM EST

Guest Speaker

Heart transplant patients often have scenarios where in the clinical presentation and pathological diagnosis on biopsy are discrepant. We will explore the utility of MMDx ® Heart in such patients through a case-based discussion. This webinar will identify the types of scenarios where gene expression profiling is useful for assessing risk of injury or rejection and will discuss the clinical application in follow-up testing.

Learning Objectives:

  • Identify Scenarios where in MMDx Heart could be useful
  • Introduction to diagnostic reporting of MMDx Heart and their interpretation as relevant to clinical presentation
  • Utility of follow up testing in MMDx Heart

How Emerging Technologies Are Filling The Gaps And Positively Impacting Post-Transplant Care

Once again, the American Transplant Congress delivered an excellent program for all attendees, and we are pleased to have played a part in its success. A highlight for us was our symposium, “How Emerging Technologies are Filling the Gaps and Positively Impacting Post-Transplant Care.” During the presentation, Dr. Rajeev Sharma and Dr. Jamil Azzi discussed how new molecular solutions can provide clinical utility and enhance the patient experience. Additionally, our patient advocate, Valen Keefer, provided a unique perspective to consider. If you missed the live presentation, you can view a recording of this talk and others on our Learning Center!

Using Molecular Diagnostics for Kidney Transplants: Getting There!

Speaker:
Gaurav Gupta
Medical Director of the Kidney Transplant Program | Virginia Commonwealth University

This presentation focused on the use of gene expression profiling for the management of kidney transplant biopsies.

Learning Objectives:

  • Recognize the significance of molecular diagnostic methods in kidney transplantation
  • Understand the complementary diagnostic value of gene expression in kidney transplant biopsies in addition to traditional histology
  • Understand how to incorporate the molecular microscope results into a management plan

Innovations in Rejection Surveillance after Heart Transplantation

Moderator:
Dr. Christopher Lawrence, BSc MBBS LLM MD(Res) MRCP(nephrology) FRCP
Director of Medical Affairs | Thermo Fisher Scientific

Guest Speaker:
Jon A. Kobashigawa, MD │ Director, Heart Transplant Program │Cedars-Sinai Medical Center, Los Angeles, California

For post-transplant management in heart patients, the endomyocardial biopsy is considered the gold standard to detect acute rejection. However, research has found that in biopsy assessments for rejection, concordance among expert pathologists is less than 67%. This presentation will explore case studies and the clinical use of novel technologies, including molecular diagnostic testing of intragraft mRNA transcripts and donor-derived cell-free DNA, for more accurate diagnosis of cellular and antibody-mediated rejection, acute rejection, and cardiac allograft vasculopathy (CAV).

Case Study

A Challenging Diagnosis in Kidney Transplantation: A case study on how the Molecular Microscope Diagnostic System for Kidney (MMDx Kidney) provides added confidence and alters management

Dr. Raghavan’s case study at 2021 ATC describes how MMDx Kidney can help in challenging kidney transplant diagnostics, how MMD Kidney reports were more consistent with the patient’s clinical course, and how they increased confidence in the patient management. We bring the full video case study as well as the written summary.

Featured Publication

New Research: Discovery and Validation of a Urinary Exosome mRNA Signature for the Diagnosis of Human Kidney Transplant Rejection

In this paper, Dr. Rania El Fekih et al. describe the discovery and validation of two urinary exosomal mRNA multigene signatures for the non-invasive diagnosis of acute TCMR and ABMR as well as chronic active ABMR in kidney transplant patients. The study determined that these exosomes show high stability, suggesting this may be a reliable and non-invasive method for allograft rejection monitoring.
