What is Genetic Carrier?
- Genetic carrier is a person that has a mutant gene of recessive disease who usually does not display or show symptoms of the disease.
- Although carriers are healthy, however, they are able to pass the genetic condition onto their offspring, who may then express the genetic trait.
- If both parents are carriers of the same disorder, there is a 25% risk that the offspring have the recessive trait in phenotype.
This test is recommended for people who:
- would like to understand their risk of having a child with a genetic disorder.
- have a family history of genetic disease
- are closely related by blood (couples)
- are pregnant or considering pregnancy
- are planning to use/ donate eggs, sperm, or embryos

Frequently asked questions
1. What should I do if my partner and I both are positive for a condition?
If you’re planning a pregnancy, you can consider In Vitro Fertilization (IVF). During the IVF process, physician will select embryos free of genetic problems through Ultra PGD/ PGT-A to implant. You can also consider other options such as implant donor’s egg or sperm that is not a carrier for the same condition.
If you’re already pregnant, you can do a diagnostic test such as amniocentesis to determine if the inherited disease was passed on to your child. Discuss with your physician for the follow up treatment.
2. Who should be tested first? Male or female?
This is flexible. However, in the cases where there is no family history of genetic disease, testing the female first is recommended due to the assessment of X-linked disorders (as male only have one X chromosome, they already be impacted if they are carrying such variants).
