PROVIDER INITIATED TEST - The CA 27-29 test measures the level of cancer antigen 27-29, a protein that may be elevated in individuals with certain types of breast cancer. This test is most commonly used to monitor treatment response or detect recurrence in people with a known breast cancer diagnosis, rather than for routine screening.
CA 27-29 levels can also be influenced by non-cancerous conditions and other cancers, so results are interpreted alongside clinical findings and additional diagnostic tests. Tracking changes in CA 27-29 levels over time is often more informative than a single measurement.
