Specimen Type: Blood

Description:

Human Epididymis Protein 4 (HE4) Test

This test measures levels of Human Epididymis Protein 4 (HE4) in the blood.  HE4 is a protein which is produced by Epithelial Ovarian Cancer Cells.  Epithelial Ovarian Cancer is the most common type of Ovarian Cancer accounting for about 90% of cases.  Many, but not all, women with ovarian cancer will show elevated levels of HE4.  HE4 is most useful as a tumor marker and can be used in some cases to monitor how well a person is responding to treatment.  The HE4 test is not recommended as a screening for cancer since other healthy types of cells also produce HE4 and the presence of HE4 is not a clear indicator that a person has ovarian cancer.

An HE4 test is typically ordered after a person has been diagnosed with ovarian cancer to establish a baseline level. Subsequent testing can then be used to monitor disease progression and response to treatment.  HE4 is often ordered along with a CA 125 test.

Turnaround for this test is typically 2-4 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.
