An Uninformative Endometrial Biopsy: What Should You Ask Next?

After an endometrial biopsy, contact your team or GP for advice if bleeding becomes heavy or discharge becomes offensive, irritating or sore. West Suffolk’s March 2026 leaflet identifies these as reasons to seek advice.¹

This Q&A is for a result discussion after sampling. Your clinician needs to interpret your report alongside the reason for the investigation and your own circumstances.

What was the sample meant to establish?

West Suffolk explains that an endometrial biopsy takes tissue from the womb lining for laboratory analysis to investigate possible abnormalities.¹

Ask which question prompted your biopsy and whether the laboratory report answers it. Request a copy of the report with the clinical explanation. You could say: “Can you explain what this sample does tell us and what you still need to find out?”

If the report uses words such as “insufficient” or “inadequate,” ask what those words mean in your specific result. Do not decide from the label alone that the investigation is complete.

Why might hysteroscopy be discussed?

The leaflet says hysteroscopy may be indicated if the biopsy is uninformative or suggests a polyp inside the womb. It describes passing a telescope into the uterus to take further samples.¹

Ask what the proposed examination would add in your case and why the clinician recommends it. You can ask whether another approach is appropriate and what information would guide that choice.

You could say: “What question would the hysteroscopy answer, and how would its findings affect the next step?” Before agreeing, request an explanation of your individual benefits, risks, comfort options and preparation instructions.

Does every uninformative result lead to the same plan?

West Suffolk describes hysteroscopy as a possible further investigation. Ask your clinician to explain the plan for your result rather than borrowing another patient’s timetable.¹

Tell the team if bleeding has continued or changed since the biopsy. Ask whether that changes the review arrangements and what symptoms it wants you to report before the next appointment. Keep any instructions it gives you with the result letter.

If you found the first biopsy painful or difficult, explain what happened. Ask how those concerns will be addressed if another examination or sample is recommended.

Who should explain the follow-up?

Ask which service is responsible for the next decision, who will contact you and whom to call if the expected arrangement does not arrive. Request the explanation in writing if you need time to absorb it.

Before you leave, try saying: “Can we write down what remains unanswered, the next recommended step and the person I should contact?” Confirm whether you need to book anything yourself.
