SCANS

Scanning has replaced many antenatal tests. Scanning is popular because it’s not invasive yet you get to see your baby on the screen. Because the equipment is expensive and needs specialised technicians, scans are expensive (if you don’t have medical aid), and not all antenatal facilities offer them. When this happens and you need to be scanned, you will be referred to an academic teaching hospital. Scans also establish the baby’s due date by measuring baby’s growth. Multiple pregnancies, placenta previa (attached too low on the womb) and some congenital abnormalities can be identified through scans. If and when a problem is detected during a scan, laboratory tests will be done before a diagnosis is confirmed.

Scans are often done at the first appointment – or at least four weeks after a missed period. It may be repeated at seven or 13 weeks.

At 16 weeks, you may be able to catch a glimpse of baby’s genitals and find out whether you are having a boy or girl. The 20 week scan checks the baby from head to toe including the heart, stomach, kidneys, spine and neck. Having a scan is your choice, but it is suggested that you have at least one scan (at 20 weeks), especially if there is a family history of congenital anomalies, a previous baby with problems or if you are taking chronic medication. Although scans are helpful, there’s no guarantee that they’re absolutely accurate.
