Chinese expert consensus on hematologic malignancy karyotyping.

Chromosomal karyotype analysis is crucial for diagnosing and managing hematologic malignancies, yet inconsistent protocols compromise reliability. To standardize practices, this consensus integrates international guidelines (WHO, ICC, ELN) with clinical expertise, providing evidence-based recommendations for specimen collection, cell culture, chromosome harvesting, banding techniques, karyotype analysis, and reporting. By establishing uniform operational standards, this initiative seeks to mitigate variability, improve detection rates, and support precision medicine in hematologic malignancies.
