Insight Molecular Diagnostics to Host Virtual KOL Event on August 17, 2026: Moving Toward In-House Heart Transplanted Organ Rejection Testing
NASHVILLE, Tenn., Aug. 11, 2026 (GLOBE NEWSWIRE) -- Insight Molecular Diagnostics Inc., (Nasdaq: IMDX), (iMDx), today announced that it will host a virtual key opinion leader (KOL) event on Monday, August 17, 2026 at 11AM ET featuring Max Jacob Liebo, MD (Loyola University Medical Center), who will join Nick Ioannou, MD, MHA (iMDx VP Medical Affairs) and Josh Riggs (iMDx CEO), to discuss the Company's GraftAssure platform, which leverages digital PCR technology to deliver reliable dd-cfDNA results for transplanted organ health monitoring. To register, click here.
The event will provide an overview of GraftAssure, currently under review by the FDA to be commercialized in kitted form for labs to test patients for kidney transplant rejection. Dr. Liebo will discuss how a kitted GraftAssure test (GraftAssureDx) can be used for in-house heart transplant rejection monitoring, as well as implications for the industry and patients.
A live question and answer session will follow.

About iMDx’s GraftAssure technology
iMDx aims to deliver proven, more affordable, faster tests that can be run in-house at local transplant center laboratories. We have designed the GraftAssureDx molecular test to be sold as a test kit so that transplant center laboratories can run tests locally. By running tests locally, laboratories can deliver critical test results to the physicians of transplant patients much more quickly than can be done with the currently available send-out tests. Our company is now seeking FDA marketing authorization to sell these kits in the U.S. If GraftAssure technology becomes available commercially as a test kit, it may be an industry-transforming event for transplanted organ rejection monitoring.
Over time, iMDx sees three potential paradigm shifts in transplanted organ health monitoring:
- Bringing testing closer to the patient: The first is a shift in the location of where donor-derived cell-free DNA (dd-cfDNA) testing is performed – migrating out of a send-out service model and into hospital-based laboratories that can deliver results locally. iMDx seeks to demonstrate that in-house testing is better for patients and physicians. (As a reminder, dd-cfDNA is an established biomarker for assessing the health of a transplanted organ through a simple blood draw.)
- Expanding the clinical role of dd-cfDNA: The second shift is the growing potential for dd-cfDNA testing, powered by digital PCR technology, to support earlier detection of allograft injury, longitudinal monitoring of transplant health, and assessment of response to emerging anti-rejection therapies.
- Advancing from rule-out testing to comprehensive decision support: The third shift is the expansion of dd-cfDNA testing from mainly being used to rule out patients’ need for confirmatory biopsy testing, to also being used proactively to predict whether a patient may be progressing toward organ rejection. This important shift is enabled by GraftAssure’s ability to measure both dd-cfDNA percentage and absolute, true concentrations as copies per milliliter of plasma.
iMDx Transplant Products and Product Candidates in Development
iMDx’s flagship transplant testing technology quantifies a molecular biomarker known as donor-derived cell-free DNA (dd-cfDNA). The Company’s scientists in Germany and the U.S. have played a critical role over the past decade in developing the science that helped establish dd-cfDNA as a trusted biomarker of transplant rejection. iMDx is commercializing this technology using a market-disruptive business strategy. Under the GraftAssure™ brand, iMDx’s transplant diagnostics include the following:
- GraftAssureCore – The company’s laboratory-developed test (LDT), currently reimbursed by CMS and performed at iMDx’s CLIA-certified laboratory in Franklin, Tennessee.
- GraftAssureIQ – A research-use-only (RUO) kit intended and labeled for non-clinical applications.
- GraftAssureDx – The in vitro diagnostic (IVD) kit currently under FDA review for use in clinical decision-making.
