Genetic testing is simply one more way of caring.
This test identifies whether you are a carrier of specific genetic disorders that may be passed on to your child. Knowing this in advance gives you the power to plan, prepare, or even breathe easy knowing the risk is low.
What Exactly Is Genetic Testing Before Pregnancy?
Carrier screening (also known as genetic testing before pregnancy) is a simple medical test that looks for inherited conditions you might pass on to your baby.By examining your DNA for gene changes, this test helps you understand the risk of passing on inherited conditions, so you can plan with confidence.
You don’t have to be sick to carry a gene. In fact, most carriers of genetic conditions have no symptoms at all.
You can get important genetic insights without discomfort, just a saliva sample, no needles required.
Why Some People Choose It
Not everyone has to go for genetic testing, but many do, and here’s why:1. You Have a Family History of a Genetic Condition
If a close relative has a condition like thalassemia, cystic fibrosis, or muscular dystrophy, testing helps you understand your chances of passing it on.2. Your Ethnic Background Is Linked to Certain Conditions
Some inherited conditions are more common in certain communities. For instance:- Thalassemia is more common among people from India, Pakistan, or the Mediterranean.
- Sickle cell anaemia tends to affect certain communities more, especially those with African or Middle Eastern roots.
3. You’ve Had a Miscarriage or a Pregnancy With Complications
Sometimes, these experiences lead couples to look for more information. Genetic testing can offer insights when trying again.4. You Simply Want to Plan Proactively
There’s nothing wrong with wanting to know more. This is your journey, and it’s okay to gather all the information you can.What Can the Test Tell You?
Genetic tests look at hundreds of conditions. Some of the most common ones include:- Thalassemia: A blood disorder that can lead to severe anaemia.
- Cystic fibrosis: Affects the lungs and digestion.
- Spinal muscular atrophy (SMA): Makes muscles weaker over time, affecting strength and movement.
- Tay-Sachs disease: Affects the nervous system.
What Happens If Your Results Are Positive?
Getting a “positive” result doesn’t mean bad news. It just means you carry a gene that could be passed to your baby if your partner is also a carrier of the same condition.In that case, you can speak with a genetic counsellor to understand:
- What are the chances your baby could be affected?
- What are your options moving forward?
- Is there a way to test your partner, too?
- Could IVF with genetic testing be considered?
When Should You Consider Testing?
It’s best to start before you begin trying for a baby; that way, you’ll have more time and choices available.But even if you’re already pregnant, don’t worry, your testing is still possible. Early consultation with your physician is essential for timely guidance and care.
How the Testing Works
Here’s a simple step-by-step overview:
- Consult your doctor or genetic counsellor
Talk through your family history and decide what kind of test you may need. - Give a saliva sample
This is usually done at home or at a clinic. No blood or painful procedures involved. - Wait for results

A genetic counsellor will explain what your results mean and help with the next steps.
Whether you decide to go ahead with the test or not, just remember this: you’re doing your best for your future child, and that’s what matters most. You're allowed to ask questions, explore your options, and make decisions that feel right for you.

FAQs on Why Some People Choose Genetic Testing Before Pregnancy
- Is genetic testing safe?
Yes. Preconception genetic testing is a safe, non-invasive way to get answers, usually with just a saliva sample. - Will it tell me if my baby will definitely have a condition?
No. It tells you if you carry certain genes. If both partners carry the same gene, the baby may have a higher risk, but it’s not certain. - Do I need to test both partners?
If one person tests positive as a carrier, the partner may also be advised to get tested for the same gene. - What if I get a positive result?
A positive result means you carry a gene, not that your baby will definitely have the condition. You’ll be supported by healthcare professionals to understand your choices.
