What does carrier testing determine?

Carrier testing specifically aims to identify whether an individual carries a gene mutation for a particular genetic condition, even if they do not exhibit any symptoms themselves. This type of testing is particularly relevant for recessive conditions, where both parents need to be carriers for there to be a risk of having an affected child. By determining if an individual is a carrier, healthcare providers can better assess the risk of passing on genetic disorders to future offspring.

This information is crucial for family planning and enables couples to make informed decisions regarding pregnancy and the potential need for further testing or interventions. Therefore, the focus of carrier testing on identifying gene mutations in individuals—regardless of whether they show symptoms—highlights its role in understanding the genetic health of future generations without directly assessing whether any offspring currently have or will have a condition.
