Genetic health checks can help couples understand the chance of them passing inherited conditions to their children. If you are planning a pregnancy either now or in the future, these tests will provide you with key information about your genetic background. In this blog, you will learn the types of couples who should do genetic health checks, why genetic health checks matter, and how they can assist with informed family planning decisions.

Suppose you and your partner decide to start a family. You focus on your diet, lifestyle, and annual health check-ups. But what about your genetic health? Sometimes, you may look and feel fit and healthy, but may still carry genes associated with inherited conditions that could be passed on to your future child.
In this article:
This points to the importance of genetic checks. Genetic tests can help understand family history and potential carriers for specific conditions. Detecting genetic problems early will help you with safe family planning and inform you of alternative options to rely on.

So when should a couple consider these checks? Let's check out the instances where genetic testing proves to be effective.

1. Before Planning a Pregnancy

Before trying to conceive, every couple should undergo genetic health checks. This will help in identifying the problem at an early stage and discussing any potential genetic considerations with their doctor.
You or your partner might be carriers of certain genetic diseases and may never experience any symptoms. Your baby, however, may inherit the disease from either one of you if both of you carry the same gene. Thalassemia, cystic fibrosis, and sickle cell anaemia are a few examples.

Why it matters:

By undertaking this testing beforehand, you can discuss with your doctor different options, such as genetic counselling or IVF with genetic screening, or you will simply get time to plan for the potential circumstances that may arise.

2. If You Have a Family History of Genetic Conditions

Family history of any condition like Down syndrome, muscular dystrophy, haemophilia, or thalassemia is a strong reason for initiating genetic health checks. The family history increases the chances of passing on these conditions to future generations.

If the condition didn’t appear in your immediate family, you may still carry the genes unknowingly. The tests can easily identify if you’re at risk

3. When Belonging to Communities with Higher Risk

Some populations or ethnic groups have a greater frequency of certain genetic conditions. For example:
  • Middle Eastern, Mediterranean, and South Asian populations are predisposed to thalassemia.
  • Sickle cell illness is more prevalent in people of African descent.

4. After Repeated Pregnancy Losses

Genetic factors can be at play if you have experienced multiple miscarriages. Some hereditary chromosomal disorders may lead to early pregnancy loss.
Such reasons make genetic health checks for both partners necessary. Always check if there’s an inherited issue that may require medical attention before trying again.

5. If You’ve Faced Fertility Challenges

Many times, fertility issues affect couples, but sometimes there's an underlying genetic reason. Low sperm count, poor quality eggs, or failed IVF cycles may be a result of chromosomal abnormalities.
Genetic screening will help you find hidden causes to your fertility issues and get appropriate guidance from a specialist.

6. During Pregnancy (If Advised by a Doctor)

Doctors can recommend you genetic health checks even after conception. If you are older (women over 35 years, men over 40), or if your ultrasounds show possible abnormalities, your doctors may discuss the option of prenatal genetic screening.
  • This can include:
  • Non-invasive prenatal tests (NIPT)
  • Chorionic villus sampling (CVS)
  • Amniocentesis
These tests easily detect chromosomal conditions like Down syndrome, Edwards syndrome, or Patau syndrome in early pregnancy.

7. If Your Partner Is a Known Carrier of a Genetic Condition

If your partner has already tested positive as a carrier of a genetic condition, you need to be tested too! The risk to your child will depend on whether both of you have the same condition. For example:
  • A child may acquire the gene but not the disorder if one or both of you are carriers.
  • If both of you are carriers, there will be a greater risk of the child being affected.

8. If You’re Opting for Assisted Reproductive Techniques

Couples who come for IVF and other infertility treatments may be advised to have a check on their genetic health. Genetic testing before implantation can ensure that only healthy embryos are transplanted.
This way, the opportunity for passing a serious genetic condition is lessened.

Why Genetic Health Checks Are Important

Genetic testing plays an informative role rather than an intimidating one. It explains and gives couples options during this process:
  • Carrier identification: It helps you understand whether you carry any genetic mutations or disorders.
  • Prepare for pregnancy: It gives you mental, emotional, and medical preparation options.
  • Prevent transmission: It reduces the chances of transmitting serious diseases.
  • Explore options: Provide an opportunity to explore options for assisted reproduction.
Genetic health checkups do not always spell trouble for a couple. It is with a sense of responsibility that may protect your future family. These tests provide knowledge and reassurance, whether it is before planning to get pregnant, after repeated losses, or during assisted fertility treatments.
Note that genetics is just one aspect of your fertility. By understanding what you can be at risk of and preparing yourself ahead of time, you can give yourself and that child the best possible winning start.

FAQs of When to Get Genetic Health Checks as a Couple

  1. Do all couples need genetic health checks before pregnancy?
    Not 100%, but genetic testing is highly recommended if family history stresses genetic diseases, one belongs to a high-risk community, and if there have been previously encountered fertility issues.
  2. Are genetic health checks painful?
    Most genetic testing is just a blood test or a saliva swab. Prenatal testing sometimes involves a minor procedure, but risks are minimal when it is done in a medical setting.
  3. Can genetic conditions be completely prevented?
    Not in every situation, but testing helps eliminate the risks. If both parents are carriers, then IVF with genetic screening or donor eggs/sperm are options that allow lower probabilities of passing on a condition.
