What to expect from a tubal dye test for blocked fallopian tubes

A clinician places a speculum in the vagina, cleans the cervix, and guides a thin tube through it. Contrast dye is introduced into the uterus while X-ray images track its path. Dye moving through both tubes suggests they are open; dye stopping may indicate a blockage, although spasm or technical factors can affect the image. The test does not assess egg quality or every cause of difficulty conceiving.

Your clinic may schedule the test after bleeding has ended and before ovulation, and will confirm that pregnancy is not possible. Follow instructions about medicines, allergies, infection symptoms, and whether you need pain relief beforehand. Cramping, light bleeding, or watery discharge can occur afterwards. Arrange advice about driving if you receive medication that causes drowsiness, and use pads rather than tampons while bleeding continues if your clinic recommends this.

Contact the clinic promptly for fever, worsening pelvic pain, heavy bleeding, faintness, vomiting, or unpleasant-smelling discharge after the test. These symptoms can signal infection or another problem needing assessment. Seek urgent help for severe pain, collapse, or trouble breathing, especially if you have a known contrast or medication allergy.

Ask which medicines are suitable for cramping, when results will be explained, and what happens if a tube appears blocked. You can also ask how the findings fit with your partner’s tests and whether another scan or fertility treatment is appropriate.
