Once again the diagnostic meeting took place at the wonderful Paul Klee Zentrum. We are very thank full to Richard Ratei, Nad Saarow (DE) who lectured about the importance of flow cytometry for the diagnosis and treatment of ALL at the Keynote session. HIs presentation was perfectly in line with the talk from the collueges of the Swiss Molecular Hematology Society, as both speaker presented their high expertise on ALL Diagnostics. The talks about the telomere length assessment by flow cytometry and leucemic stem cells in AML and the crash course with case presentation offered various insights into the diagnostic world of flow. We thank all speakers and participiants! We are looking back at a once again successful Meeting and already happily forward to the next SSH Diagnostic Meeting in 2026!
