Researchers watch and wait: can unexplained low blood counts predict bone marrow disease?

This study follows 300 people who have persistent low blood cell counts (anemia, low white cells, or low platelets) that cannot yet be diagnosed as a bone marrow disease called myelodysplastic syndromes (MDS). The goal is to track how often these patients progress to MDS or related conditions over time. No treatment is given; the study simply observes and records outcomes to better understand the natural history of these pre-MDS states in a Chinese population.
