The global fluorescent in situ hybridization (fish) probe market encompasses a diverse range of molecular diagnostic tools designed to identify and visualize specific DNA or RNA sequences within cells and tissues, supporting accurate disease diagnosis and research applications. By type, the market is segmented into DNA probes, widely utilized for detecting chromosomal abnormalities and gene amplifications in cancer and genetic studies, and RNA probes, primarily used for analysing gene expression and detecting RNA viruses, offering high sensitivity and specificity. By technology, the market includes quantitative FISH, enabling precise measurement of gene copy numbers, multiplex FISH, allowing simultaneous detection of multiple genetic targets for complex analyses, and conventional FISH, extensively used in cytogenetic laboratories for standard chromosomal mapping and visualization. By application, FISH probes find broad use in cancer diagnostics, genetic disease detection, and cytogenetics, as well as in other fields such as microbial identification and prenatal testing. By end user, the market serves research laboratories, clinical diagnostic centers, and companion diagnostics applications, underscoring its expanding role in precision medicine, translational research, and targeted therapy development. Collectively, advancements in probe labeling, imaging systems, and automation continue to enhance the accuracy, throughput, and clinical utility of the FISH probe market worldwide.
A major trend in the fluorescent in situ hybridization probe market is the shift from using FISH probes mainly for general cancer diagnostics to employing them as companion diagnostics directly tied to specific therapies. As per the U.S. FDA, the FDA had approved a PMA supplement for the Vysis ALK Break Apart FISH Probe Kit to include an indication for ENSACOVE (ensartinib) in non-small cell lung cancer (NSCLC), linking FISH testing directly to treatment decision making. This development highlighted the move from broad diagnostic use towards therapy-linked precision testing, which not only improved clinical adoption of FISH probes but also strengthened their role in guiding targeted cancer treatments.
A key trend in the global market is the shift from highly restrictive regulatory requirements to a more streamlined approval pathway. For example, in June 2025, the U.S. FDA reclassified FISH-based devices for detecting chromosomal abnormalities from the more restrictive Class III to Class II (special controls), which simplified regulatory requirements and facilitated faster clinical adoption. This change reflected the move from lengthy, complex approval processes to a more efficient regulatory pathway, which reduced barriers for manufacturers, accelerated product approvals, and supported faster market availability of advanced FISH probe products.

A key driver in the FISH probe market is the rapid improvement in technologies, such as multiplex FISH, which make probes more specific, faster and more sensitive. For example, in March 2024, Oxford Gene Technology IP Limited’s Cytocell launched its latest multiplex FISH panel capable of simultaneously detecting multiple chromosomal abnormalities in a single assay, which further reduced processing time while improving sensitivity and specificity.
A major restraint in the FISH probe market is the high cost associated with the FISH assays, which restricts their adoption across clinical settings. This is especially challenging for complex tissue analyses, where advanced probe design and specialized handling are required. As a result, the expensive nature of these assays slowed widespread implementation, limited market growth, and accessibility of FISH-based diagnostics.
An opportunity in the FISH probe market is its expanding use for hematologic cancers, where chromosomal abnormalities play a critical role in diagnosis and treatment selection. Recently, Empire Genomics and BioDot launched hematology-focused FISH probe panels for multiple myeloma, validated on the BioDot CellWriter S platform. This reflected a strong opportunity for companies to develop disease-specific panels that enhance diagnostic efficiency and automation.
The North America region dominated the market with a revenue share of 47.23% in 2025.
