If you are negative for one or more genetic conditions on a carrier screen, it reduces the chance that you are a carrier. However, no genetic test can detect all of the possible gene variants that could cause a disease. This means that, even if you test negative, there is a small chance that you may still be a carrier for a genetic condition.
If you have a positive test result, it means that a gene variant (or change) has been identified and that you are a carrier of a certain genetic condition. While carriers are usually healthy, you may have an increased risk of having a child affected by that condition. To better understand this risk, your reproductive partner should be tested to see if they are a carrier for the same genetic condition.
