HUMAN EPIDIDYMIS PROTEIN 4

The human epididymis protein 4 (HE4) test measures the level of HE4, a protein produced by certain types of cancer cells, in the blood. This test is used to diagnose and monitor ovarian cancer, assess the effectiveness of treatment, and detect recurrences. Elevated HE4 levels can indicate the presence of ovarian cancer or other conditions, such as endometriosis and benign ovarian tumors. The HE4 test is valuable for guiding treatment decisions, evaluating therapy outcomes, and monitoring for cancer recurrence in patients with ovarian cancer.
