Theratyping and theranostics are two distinct approaches to advance CF treatment.

The challenges, advantages and disadvantages of both approaches are discussed here. While theratyping in cell lines offers ease of use, cost-effectiveness, and standardized platforms for experimentation, it misses physiological relevance and patient-specificity. Theranostics, on the other hand, provides a more human-relevant model for personalized medicine approaches but requires specialized expertise, resources, and access to patient samples.
