What is SIS test?
April 13, 2017
I have been recommended to have an SIS – what is this?
An SIS – Saline Infusion Sonography, is a type of ultrasound test where a small amount of saline is passed into the uterus to visualise the uterine cavity and fallopian tubes. It is one of the more basic forms of checking that the cavity is normal and the tubes are open – the practitioner watches the fluid travelling on scan to assess these factors.
It is quick and relatively pain free (it can sometimes induce period like cramps) but most people don’t feel any pain. It can determine some important factors – what direction the neck of the uterus is facing, if there are any polyps or fibroids present and if the fallopian tubes are open and not blocked.« Return to Blog
