Pre-Natal Screening & Test

Pre-natal screening and tests can provide vital information to expecting parents about the health of their unborn baby. This important testing helps identify potential problems so that any necessary steps can be taken before birth. It is important to note that this type of testing is not mandatory and that the decision on whether or not to proceed with it rests with the mother and her medical team. Pre-Natal Screening and Testing provides a way for parents to make informed decisions about their pregnancy and their newborn's health.

Types of Pre-Natal Screening and Tests

There are various types of pre-natal screening and testing available. These include ultrasound scans, which use sound waves to create images of the baby; non-invasive prenatal testing (NIPT), which involves taking a blood sample from the mother to analyse the baby's chromosomes; chorionic villus sampling (CVS), which involves taking a small sample of cells from the placenta; and amniocentesis, which requires a small amount of amniotic fluid to be taken for testing.

When should one see a doctor for Pre-Natal Screening and Tests?

It is recommended that pregnant women see their doctor as soon as they find out they are pregnant. During the first prenatal visit, the doctor will discuss the available screening and diagnostic tests and when they should be done. Screening tests can be performed anytime between 10-14 weeks into the pregnancy to detect any potential genetic abnormalities or other problems. Diagnostic tests such as amniocentesis can be performed anytime between 15-20 weeks of pregnancy to provide more detailed information about a developing baby's health. Expectant mothers need to make all necessary appointments with their doctor to ensure a healthy pregnancy and baby.

Risk factors for Pre-Natal Screening & Tests

The main risk factors for Pre-Natal Screening & testing are mothers aged over 35, a family history of certain genetic conditions or birth defects, multiple pregnancies, and previous pregnancies with complications. Additionally, if the mother has tested positive for HIV or other infections during pregnancy or has had exposure to certain medications or chemicals, it may be recommended that she undergo Pre-Natal Screening and tests. Lastly, if the foetus is showing signs of slowed growth or abnormal development on ultrasound scans, then further testing may be advised.

How should a patient prepare for Pre-Natal Screening & Tests?

Before undergoing Pre-Natal Screening and tests, it is recommended to have a good night's rest and eat a light snack. Avoid alcohol, smoking, and caffeine for 24 hours before the test. Drink plenty of fluids and wear comfortable clothing that can be easily removed. It may also be necessary to provide a urine sample on the day of the test. Additionally, it is advised to bring any relevant medical records or notes from previous appointments. Finally, if possible, arrange for someone to accompany you during the test.

What are the possible results of a Pre-Natal Screening & Test?

Pre-natal screening and test results can indicate whether a pregnancy is likely to result in a healthy baby or one with developmental issues such as Down syndrome. The test may also detect chromosomal abnormalities, spina bifida, abdominal wall defects, and heart conditions. If a problem is detected, the patient will be able to make informed decisions about their pregnancy and have time to prepare for any extra care that may be needed. Results may also come back as normal or inconclusive, meaning further tests are required.


Pre-natal screening and testing are an important part of prenatal care for expecting mothers. It helps to assess the health of your baby and identify any potential issues or complications before birth. The tests are simple, noninvasive, and often provide an early diagnosis of any potential health issues. The results of these tests can give parents peace of mind in knowing that their baby is healthy or provide them with the opportunity to make informed decisions if any issues arise. Pre-natal screening and testing are crucial steps in ensuring a healthy pregnancy for both mother and baby.

1. What are the differences between screening and diagnostic tests for prenatal health?

Screening tests provide an estimate of the risk that a foetus has a certain genetic disorder or birth defect, while diagnostic tests can confirm or rule out the presence of a specific condition with greater accuracy.

2. What methods can be used to detect foetal abnormalities during pregnancy?

Common methods used to detect foetal abnormalities include ultrasound imaging, maternal blood testing, and amniocentesis.

3. How soon after conception should pre-natal testing occur?

Pre-natal testing should begin as early in pregnancy as possible to ensure accurate results. Depending on the test being taken, most are typically done between 10-14 weeks of gestation.

4. Is there any difference between pre-natal screening and genetic counselling?

Pre-natal screening provides estimates of the risk of certain conditions from an isolated sample or test result, while genetic counselling involves discussing family history and other factors that may influence the risks of inherited diseases.
