Patent ID: 6972180

Claim:
A method of using a salivary biomarker to differentially diagnose carcinoma of the breast in a human test subject, said method comprising: providing a salivary secretion specimen from a human subject to provide an individual salivary biomarker diagnostic for carcinoma of the breast, said biomarker soluble in said salivary secretion and selected from the group consisting of cancer antigen 15-3, tumor suppressor oncogene protein 53, oncogene c-erbB-2 and combinations thereof; using the salivary secretion concentration of said individual biomarker to compare with a protein biomarker reference panel, said reference panel including at least one of cancer antigen 15-3, tumor suppressor oncogene protein 53, oncogene c-erbB-2 protein biomarker, and combinations thereof; and differentially identifying the diagnosis for said subject indicated by said comparison.
