A Twin Pregnancy Scan is a private ultrasound tailored to pregnancies with two babies. The assessment is adapted to gestation and may include fetal viability, the number of fetuses, chorionicity and amnionicity where visible, fetal position, placental appearances, amniotic fluid and growth or wellbeing observations where appropriate.

The Twin Pregnancy Scan is £160 at Tunbridge Wells and Orpington and £200 at Canary Wharf.

Twin pregnancies can be assessed from early pregnancy onward. The scope changes with gestation: early scans focus more on pregnancy location, viability and twin type, while later scans can include wellbeing and growth observations.

Where the relevant ultrasound features are visible, chorionicity can be assessed to determine whether the twins appear to share a placenta or have separate placentas. Early pregnancy is often the best time to establish chorionicity reliably.

Amnionicity describes whether the babies are within separate amniotic sacs or share one sac. It is an important part of classifying a twin pregnancy.

Chorionicity affects pregnancy risk and the type and frequency of surveillance recommended through your NHS maternity or fetal medicine pathway. Monochorionic pregnancies need specialist follow-up because complications can differ from dichorionic pregnancies.

Yes. Fetal cardiac activity is assessed for each fetus when appropriate to gestation and technically visible.

Yes, where gestational age and scan scope make this appropriate. Each fetus is measured separately, and in later pregnancy the estimated size of each baby can be compared.

In later pregnancy, separate fetal measurements may allow comparison of the babies' estimated sizes. A private scan does not replace formal NHS serial growth surveillance, particularly in higher-risk twin pregnancies.

Yes. Placental location and the fluid around each baby are reviewed where technically possible and appropriate to gestation.

A focused private scan may identify findings that warrant concern, but TTTS surveillance in monochorionic twins belongs within a specialist NHS or fetal medicine pathway. This scan does not replace scheduled specialist surveillance.

No. Twin pregnancies usually require a defined NHS surveillance plan based on chorionicity and individual risk. Private scans should complement, not replace, your NHS maternity or fetal medicine care.

Yes. You receive a same-day digital report documenting the findings for each fetus and ultrasound images where obtained.

No. You can self-refer and book directly. If your maternity team has arranged specialist twin surveillance, continue that pathway even if you also book privately.

Seek prompt maternity assessment for heavy bleeding, severe or worsening abdominal pain, leaking fluid, regular contractions when not expected, reduced or changed fetal movements later in pregnancy, fainting, fever or feeling acutely unwell.
