Ultrasound Scans in Late Pregnancy
Additional ultrasound scans may be recommended during pregnancy if there are concerns about your baby’s growth, movements, or overall wellbeing. These scans help assess your baby’s growth, amniotic fluid levels, and placental function.
Most women will not require further ultrasounds after the routine 18–20 week anatomy scan. However, some pregnancies may require ongoing monitoring with additional scans to ensure your baby continues to grow and develop appropriately.
If your pregnancy continues beyond your due date, ultrasound assessments may also be arranged to check amniotic fluid levels and monitor your baby’s wellbeing.
Cardiotocography (CTG)
A cardiotocograph (CTG) is a monitoring test used in late pregnancy to assess your baby’s heartbeat and movement patterns. This test can provide reassurance about your baby’s wellbeing and is commonly recommended if:
You are overdue
There are concerns about reduced fetal movements
There are medical or pregnancy-related complications requiring closer monitoring
The test is non-invasive and usually takes around 20–40 minutes.
Blood Tests in Late Pregnancy
Most women will not require additional blood tests after gestational diabetes screening at 24–28 weeks. However, some women may need further testing later in pregnancy depending on their individual circumstances.
Women who are Rhesus (Rh) negative or who have developed blood group antibodies will usually have repeat blood tests between 34 and 36 weeks of pregnancy.
Additional blood tests may also be recommended for women with conditions such as:
High blood pressure or pre-eclampsia
Gestational or pre-existing diabetes
Anaemia or low iron levels
Other medical conditions requiring closer monitoring during pregnancy
