Proteomics focuses on studying the configuration and operation of proteins. It is usually placed under the wider umbrella of genetic testing, because much of the research and results overlap. Note that proteomics does not study genetics or genes directly, but examines the proteins themselves to classify them and see how they interact.
For example, the protein structure and interactions of damaged DNA can lead scientists to developing new treatments and new drugs that affect only the damaged proteins. By isolating proteins, it is possible to ensure that future examinations of the same proteins will bring the same conclusion; this is similar to the classification of genes which allowed various genetic treatments and therapies. It also allows the modeling of proteins with enzymes, other proteins, and genetic structures, giving a better understanding of how each individual protein acts and reacts in the body.
