Summary

- It helps identify any structural issues early.
Introduction
Pregnancy involves several important medical checkups, and one of the key scans is the anomaly scan.
This test helps doctors understand how your baby is developing and whether everything is progressing normally.
However, the timing of this scan plays a very important role in getting accurate results.

Which Week is Best to Take an Anomaly Scan?
While the best time to take an anomaly scan is between 18 and 22 weeks of pregnancy, doctors recommend taking it at 20 weeks as it provides them with the best possible view of the baby’s anatomy and development.
Why is the 18–22 Week Period Ideal?
- The baby’s organs have developed enough to check for abnormalities
- The baby’s size allows detailed scanning
- Movement of the baby helps doctors view different parts clearly
- Early detection allows doctors to plan further care if needed.
Can Anomaly Scan Be Done Earlier Than 18 Weeks?
Before 18 weeks:
The baby’s organs are still developing, which makes it difficult for a detailed evaluation.
Certain structural abnormalities may not be easily identified at this stage.
A follow-up scan may be recommended later for a more detailed assessment.
Can the Scan Be Done After 22 Weeks?
Yes, it can still be done, but it’s not the preferred timing.
After 22 weeks:
- The baby is bigger, making some areas harder to examine
- There may be less time for important medical decisions
- The baby is larger and takes up more space in the uterus, so it becomes hard to capture the whole body or certain organs in a single clear view.
What If You Miss the Recommended Time?
If the scan is not done within the 18–22 week window:
- Your doctor will still advise getting it done as soon as possible
- Some conditions may be harder to detect
- Even if it’s done later than recommended, the scan still provides valuable information and remains important.
Who Should Be More Careful About Timing?
Some pregnancies need extra attention when scheduling this scan:
- Women with high-risk pregnancies
- Those with a family history of genetic disorders
- Pregnancies involving diabetes, hypertension, or previous complications
- Women above 35 years of age.

FAQ
1. Can an Anomaly Scan be done at 17 weeks?
For some expectant mothers, doctors may recommend an early anomaly scan, also known as an early target scan, between 16 and 18 weeks to screen for abnormalities. However, since the baby’s development is still ongoing, a follow-up scan may be needed.
The ideal time for a routine anomaly scan is between 18 and 22 weeks, as it provides the most accurate and detailed view of the baby’s structures.
2. Is 20 weeks the best time for the scan?
Although 20 weeks is the best time, it is not the only suitable time. The scan can be performed effectively between 18 and 22 weeks of pregnancy.
3. Is 23 weeks too late for an anomaly scan?
It’s a little beyond the ideal period, but the scan can still be done, though with some limitations.
4. Why is the anomaly scan done in the second trimester?
By this time, the baby’s organs are developed well enough to be seen clearly and assessed more accurately during the scan.
5. How early should I book my anomaly scan?
It’s best to book it around 12–14 weeks to ensure you get an appointment during the ideal time.
