The application of proteomics is poised to revolutionize Clinical Diagnosis by providing a dynamic view of a patient's health status, directly reflecting current physiological conditions and disease states. Unlike genomics, which provides a static blueprint, the proteome captures real-time changes in protein expression, localization, and activity that are central to disease mechanisms in conditions like cancer, cardiovascular disease, and neurological disorders.

In personalized medicine, proteomics offers critical insights for tailoring therapeutic strategies. By profiling a patient's specific protein signature, including variants and PTMs, clinicians can predict drug responsiveness, identify resistance mechanisms, and select the most appropriate targeted therapy. For instance, analyzing protein profiles in tumor tissues or patient biofluids can categorize patients into responder and non-responder groups before treatment even begins, significantly improving patient outcomes and reducing the use of ineffective therapies within the clinical space.
