State‐of‐the‐art FISHing: Automated analysis of cytogenetic aberrations in interphase nuclei

Interphase fluorescence in situ hybridization (i‐FISH) is a powerful tool for visualizing various molecular targets in non‐dividing cells. Manual scoring of i‐FISH signals is a labor intensive, time‐consuming, and error‐prone process liable to subjective interpretation. Automated evaluation of signal patterns provides the opportunity to overcome these difficulties. The first report on automated i‐FISH analysis has been published 20 years ago and since then several applications have been introduced in the fields of oncology, and prenatal and fertility screening. In this article, we provide an insight into the automated i‐FISH analysis including its course, brief history, clinical applications, and advantages and challenges. The lack of guidelines for describing new automated i‐FISH methods hampers the precise comparison of performance of various applications published, thus, we make a proposal for a panel of parameters essential to introduce and standardize new applications and reproduce previously described technologies. © 2012 International Society for Advancement of Cytometry
