Viability Scan

A viability scan is a non-invasive diagnostic test used to assess the health of a developing pregnancy. It uses ultrasound technology to determine if the embryo is likely to be viable and can assess the fetal heart rate and identify multiple pregnancies.

This scan can also determine the dates and gestational age of the pregnancy, allowing for more accurate monitoring throughout. The viability scan is an invaluable tool in helping couples achieve their dream of having a baby.

What is a viability scan?

A viability scan is an ultrasound procedure used to assess the development and progress of a pregnancy. It involves examining the gestational sac, foetus, and surrounding fluid to determine if a pregnancy is progressing normally.

A viability scan may also be referred to as an early pregnancy scan or a reassurance scan. The scan can usually detect a heartbeat after 6 weeks of gestation, although, in some cases, it may not be visible until 8–9 weeks.

Following the scan, the results will be discussed with patients and any further tests recommended.

Who qualifies for a viability scan?

Anyone over 6 weeks pregnant can qualify for a viability scan. The purpose of the scan is to confirm if a pregnancy is viable, meaning that it has an adequate fetal heartbeat and growth.

Patients with any kind of bleeding or pain should seek medical advice before booking a viability scan. Scans are usually performed between 6 and 10 weeks after the first day of the last menstrual period.

If a patient's dates are uncertain, they may be asked to wait until they are 8–10 weeks pregnant before booking their scan.

How should a patient prepare for a viability scan?

Patients should come to the viability scan appointment with a full bladder and avoid eating or drinking anything for two hours prior. It is important to wear comfortable clothing, as the patient may need to remove some of it for the scan.

Loose trousers are preferable, as some ultrasound gel needs to be put on the abdomen area. It can also help if patients bring a record of their medical history, including any relevant pregnancy information.

When would a doctor suggest undergoing a viability scan?

Patients may be advised to opt for a viability scan if they are experiencing irregularities in their menstrual cycles, or if there is a suspicion of miscarriage or ectopic pregnancy.

Doctors may also recommend it after an IVF cycle to check whether the embryo has been implanted and is continuing to develop normally. In cases where the patient has had difficulty conceiving, a viability scan can provide valuable insight into the progress of the pregnancy.

Finally, it is often recommended that women over 35 have one for reassurance that the pregnancy is progressing as expected.


A viability scan is an important medical tool used to assess the health of a pregnancy. It can provide information on the location of the embryo and its heartbeat, as well as other vital factors.

By utilizing this procedure, fertility experts are empowered to make informed decisions regarding the viability of the pregnancy.

This simple and quick test can give expecting parents peace of mind and ensure that their child has the best possible chance for a healthy start in life.
