What is the viability scan?
The viability scan is typically the first ultrasound performed in pregnancy, usually between 7 and 10 weeks of gestation. It is sometimes referred to as the “dating scan” because it helps to confirm how far along the pregnancy is. This early scan provides vital information about the health and development of the pregnancy.

What is the aim of the viability scan?
- Confirm that the pregnancy is located within the uterus (to exclude an ectopic pregnancy)
- Check that the baby has a heartbeat and is developing normally
- Determine the number of embryos (single or multiple pregnancy)
- Accurately date the pregnancy and provide an estimated due date (EDD)
- Identify any visible early abnormalities
- Assess for internal bleeding/hematomas or any signs of complications
How is the viability/dating scan performed?
The scan is usually performed transabdominally (through the tummy). However, in very early pregnancies or when clearer images are needed, a transvaginal scan may be recommended. Both methods are safe and provide valuable information for early pregnancy assessment.
Can you have an early viability scan at 6 weeks?
Yes, in some cases, a viability scan can be performed as early as 6 weeks. However, it is important to note that at this stage, the baby and heartbeat may be too small to be clearly visible. If performed this early, a follow-up scan may be recommended a week or two later for more conclusive results.
Early scans at 6 weeks may be particularly helpful for women with a history of miscarriage, ectopic pregnancy, or fertility treatment.
Should you have a private viability scan?
Choosing a private viability scan offers several benefits:
- Early reassurance about the pregnancy
- Minimal waiting times and flexible appointment scheduling
- A more personalised and unhurried experience
- Access to expert specialists and advanced scanning technology
Many expectant parents opt for a private scan to gain peace of mind in the early weeks, especially if they’ve experienced complications in previous pregnancies or simply wish to check on the baby’s development sooner than the routine NHS scan.
Who should consider a viability scan?
A viability scan is especially recommended for:
- Women experiencing pain, bleeding, or other concerning symptoms
- Those with a history of miscarriage or ectopic pregnancy
- Women undergoing fertility treatment
- Anyone seeking early reassurance about their pregnancy
What happens after the viability scan?
Following your scan, the doctor will discuss the findings with you. If everything appears normal, you will be advised on the next steps, which may include scheduling your nuchal screening scan at around 11–13 weeks. If any concerns are noted, appropriate follow-up care and further investigations will be recommended.
