Graft-Versus-Host Disease (GVHD) is a serious complication that can occur after bone marrow or stem cell transplants. It develops when the donor's immune cells recognize the recipient's body as foreign and begin attacking healthy tissues. While GVHD is primarily diagnosed through clinical symptoms and tissue examination, blood testing plays a crucial role in monitoring immune system activation and guiding treatment decisions.
This test measures soluble IL-2Ra/CD25 levels in the blood, which serve as important biomarkers of T-cell activation. Elevated levels can indicate immune system activation associated with GVHD development, helping healthcare providers detect the condition early and monitor the effectiveness of immunosuppressive treatments.
There is no single blood test that definitively diagnoses GVHD, as the condition is typically confirmed through clinical evaluation and tissue biopsy. However, blood tests are fundamental for detecting early signs of immune system activation, monitoring the severity of the immune response, and assessing the effectiveness of treatment interventions.
When GVHD occurs, the donor's T-cells become activated as they recognize the recipient's tissues as foreign. This activation leads to the release of various inflammatory markers, including soluble IL-2Ra/CD25. Monitoring these markers through blood testing provides valuable insight into the immune response and helps guide treatment decisions to prevent or manage GVHD complications.
