Low HE4 (human epididymis protein 4): what it means
A HE4 (human epididymis protein 4) result below the normal range is considered low. Here is what a reduced HE4 (human epididymis protein 4) can point to, and when it is worth discussing with a doctor.
Reference range: ~<70–140 pmol/L depending on menopausal status; used WITH CA-125 (the ROMA score) to gauge the risk that an ovarian mass is cancer, not as a stand-alone screen
Understand your full resultWhat a low HE4 (human epididymis protein 4) can mean
- Lower estimated risk of ovarian cancer — a low HE4, with a low CA-125, is reassuring in the assessment of an ovarian mass.
- Normal in health — expected; but HE4 is not used to screen healthy women.
When to discuss with a doctor
HE4 is a specialist tool for characterising an ovarian mass that has already been found, not a screening test to 'check for ovarian cancer' in a woman with no symptoms or mass. Used with CA-125 and menopausal status in the ROMA score, it helps decide the level of cancer risk and whether referral to a gynaecological cancer centre is warranted. A raised result is interpreted alongside imaging and the clinical picture, and can have benign explanations such as kidney impairment. Mediora.AI shows HE4 alongside CA-125 and the other tumour markers so it is read in context; the ovarian-mass assessment and any ROMA calculation belong with your gynaecologist.
