Genetic screening before conception is now more frequent than ever. The tests can inform you as to whether you are a carrier of specific inherited medical conditions, even if you are entirely healthy. Being aware of this knowledge earlier can ensure that you and your partner are making informed, sure decisions regarding your future family.

What Is a Genetic Health Check?
A genetic health screening is a medical test that scans your DNA for alterations or "mutations" in particular genes. These mutations may at times result in inherited disease.You and your partner may both be carriers of the same gene mutation, but not suffer from the condition yourself. If you and your partner both pass on that mutation to your baby, there's a greater chance the baby might get the condition. Genetic screening allows you to learn about these risks before you get pregnant.
Why Do Couples Choose Genetic Testing Before Pregnancy?
There are several reasons that couples include genetic health screening as part of pre-pregnancy planning.1. Identifying Risk of Inherited Conditions
Certain illnesses, such as thalassemia, sickle cell anaemia, cystic fibrosis, and some metabolic diseases, are inherited. You may not know you are a carrier until you are tested.A genetic health screening will tell you if you or your partner has such genes and how these may impact your baby's health.
2. Informed Pregnancy Decisions
If the test reveals that you and your partner are both carriers of the same condition, then you can:- Consult a genetic counsellor for advice.
- Discuss assisted reproductive treatments, including IVF with genetic screening.
- Plan early treatments or medical procedures after birth.
3. Peace of Mind
For most couples, genetic testing is really about reassurance. Even if no risks are detected, knowing your genetic status can give you greater confidence going forward.4. Special Considerations for Certain Backgrounds
Certain communities have a greater risk of inheriting specific genetic conditions. If you and your spouse have such backgrounds, genetic testing may be particularly helpful in knowing your risks.5. Age and Planning Ahead
Even though age itself is not the cause of genetic disorders, pregnancies at older ages may have a slightly higher risk of specific chromosomal conditions. In these situations, genetic health screening can be a helpful part of planning ahead.How Does Genetic Testing Work?
It is easy and painless in the vast majority of situations:- Consultation: You sit down with a doctor or genetic counsellor to review your family and medical history.
- Sample Collection: This may be a blood test, saliva sample, or cheek swab.
- Lab Analysis: Experts examine your DNA for known mutations.
- Results and Counselling: You get your results and talk about what they mean for your pregnancy options.
If You’re Both Carriers
Carrying the gene does not mean you can't have a healthy child; it just means you're at greater risk. Some possible options are:- Preimplantation Genetic Testing (PGT) with IVF
- Prenatal Testing during pregnancy to screen the health of the baby early
- Donor sperm or eggs from a non-carrier
- Considering adoption if you don't want to pass along a condition
Common Myths About Genetic Testing
Myth 1: Only couples with a family history need it.
Truth: Many carriers don’t know they have the gene because it can skip generations.Myth 2: It predicts everything about the baby’s future health.
Truth: It only detects certain known mutations, not every possible condition.Myth 3: Being a carrier means you can’t have children.
Truth: You can still have healthy children; you may just need additional planning.Benefits of Genetic Health Checks Before Pregnancy
