Is OncuraKit considered a liquid biopsy?

OncuraKit uses circulating microRNA from urine, which is a form of liquid biopsy — a broad term for any diagnostic test that analyzes tumor-derived material (DNA, RNA, proteins, or cells) from a body fluid rather than from a tissue biopsy. Traditional liquid biopsies analyze circulating tumor DNA (ctDNA) or circulating tumor cells (CTCs) from blood. OncuraKit analyzes circulating extracellular miRNA from urine. The advantage of the Yenos miRNA approach over ctDNA-based liquid biopsies is that cancer-associated miRNA overexpression begins earlier in carcinogenesis than ctDNA mutations accumulate to detectable levels, potentially enabling earlier detection.
