Leukemia Molecular Diagnostics segmentation by type distinguishes DNA‑based, RNA‑based, and protein‑based assays. DNA‑based tests, which detect somatic mutations and chromosomal translocations, dominate the market because they underpin most FDA‑cleared panels and support precise therapeutic matching. RNA‑based assays focus on fusion transcripts and gene‑expression signatures, offering higher sensitivity for certain sub‑types such as acute lymphoblastic leukemia. Protein‑based diagnostics, although a smaller niche, provide functional readouts of pathway activation and are increasingly integrated with multiplex platforms. Collectively, these three sub‑categories account for the full market valuation, with DNA‑based methods contributing roughly 60 % of revenue, RNA‑based 30 %, and protein‑based 10 %. The distribution reflects the relative maturity of the technologies, reimbursement frameworks, and the clinical decision‑making weight assigned to each molecular layer. Understanding this type‑level taxonomy is essential for forecasting investment flows and R&D prioritization within the Leukemia Molecular Diagnostics market.
