Obstetrical ultrasounds can be an exciting event during a pregnancy as there is a chance to see your baby before it is born and possibly learn the sex so that you can plan the baby’s room and choose a name. Your healthcare professional has ordered this exam for medical reasons. Family members are allowed to attend the exam with you.
To allow the sonographer to concentrate fully on the task at hand, questions will be answered once pertinent data has been obtained. Video cameras or other forms of recording are not permitted. Please see reception at the front desk on how to obtain images of your exam.
What is the Prep?
For this exam there is no prep. You may eat and drink normally.
What will the sonographer do?
For this exam, you will be asked to lie down on a table and an odourless, water-soluble gel will be applied to your skin by the sonographer. This gel helps to transmit high frequency sound waves and allows for easy movement of the probe over the skin. As the probe glides over your pelvic area, pictures are taken of the baby. You should not experience pain or discomfort from this examination. The sonographer will leave the room once all images are complete. You will be directed to a change room after which you will be free to leave.
Integrated Prenatal Screening (IPS)
This screening test combines measurements from a nuchal translucency ultrasound and two blood tests to estimate the chances of a developing baby having Down’s Syndrome. The IPS takes into account the measurement of the NT ultrasound and the level of the proteins and other substances measured in the blood tests. It then adjusts for the woman’s age and gives a numerical estimate of the chances of Down’s Syndrome. In addition, unlike the first trimester screening assessment (FTS) which also screens for Down’s Syndrome, the IPS will determine if there is also a chance of Spina Bifida.
The NT ultrasound measurement is completed at the same time as the first blood test. The sonographer will complete the ultrasound portion of the IPS form. This must be completed prior to the blood work as the ultrasound data must be sent along with the blood work for interpretation. The combined data is sent to the Genetics Department at Credit Valley Hospital for analysis. The second blood test does not require an accompanying ultrasound.
Results
The ultrasound and first blood test are completed between 11 weeks, 2 days and 13 weeks, 3 days of the pregnancy. The second blood test is done between 15-18 weeks. The results of the IPS are sent to your healthcare practitioner (obstetrician, family physician, midwife, nurse practitioner) approximately one week after the second blood test.
