A 5-year retrospective study published in the British Journal of Haematology examined changes in practice within a haematological malignancy diagnostic service. The study found that there has been an increase in the use of ancillary immunophenotypic, molecular, and cytogenetic assays to supplement morphological assessment in order to improve diagnostic accuracy and treatment options. The study also observed an increase in the number of testing modalities per specimen, particularly in genomic testing, which has led to more confident diagnoses of chronic myeloid disease. The findings highlight the need for increased scientific capacity and training within laboratories to support the analysis of these complex assays. [Extracted from the article]
