What an endometrial biopsy is
An endometrial biopsy is the taking of a small sample of tissue from the lining of the uterus so that it can be examined under the microscope. It is the key investigation for endometrial pathology and is carried out in the office, without a hospital stay.
When it is recommended
- Abnormal uterine bleeding.
- Bleeding after the menopause.
- A thickened endometrium on ultrasound.
- Investigation of infertility or recurrent miscarriage.
- Monitoring during hormone treatment, where this is considered necessary.
The procedure
A sample of endometrium is taken with a fine flexible catheter passed through the cervix. The examination takes a few minutes. You may feel cramping, similar to period pain, which settles quickly. Light bleeding for one to two days is to be expected. The result of the histological examination determines the next steps.
