Innovative Blood Test Could Revolutionize Bone Marrow Sampling for Leukemia Detection

Researchers at the Weizmann Institute of Science have developed a groundbreaking blood test that could serve as a less invasive alternative to traditional bone marrow sampling for diagnosing leukemia and related blood disorders. This new diagnostic tool leverages advanced genetic sequencing of blood stem cells that migrate into the bloodstream—a process that naturally occurs and contains vital information about blood health.

The study, led by Dr. Nili Furer and in collaboration with international medical teams, focused on myelodysplastic syndrome (MDS), an age-associated condition where blood stem cells fail to mature properly, potentially progressing to leukemia. Traditionally, diagnosing MDS involved a bone marrow biopsy, a procedure that is invasive, painful, and often uncomfortable for patients.

In this innovative approach, a simple blood sample followed by high-precision single-cell genetic analysis can reveal early signs of MDS and estimate the risk of developing leukemia. The technique identifies rare blood stem cells that exit the bone marrow and circulate in the bloodstream, providing crucial diagnostic insights. Interestingly, these circulating stem cells also serve as biomarkers of biological age, with notable differences observed between males and females, possibly explaining why men are more prone to blood cancers.

This research not only opens doors for less invasive diagnostics but also has the potential to be expanded to detect various blood-related illnesses. The ongoing clinical trials are testing the efficacy and accuracy of this blood test at multiple medical centers worldwide.

Dr. Shlush, a senior scientist at the institute, also practices at Assuta Medical Center and Maccabi Healthcare Services. His new medical school aims to integrate research and clinical practice, training future physician-scientists equipped with cutting-edge knowledge to advance medicine.

Overall, this innovative blood test heralds a new era in hematology, offering hope for earlier, safer, and more accessible diagnosis of blood disorders and leukemia.
