Genetic Compatibility Test London – Carrier Screening for Couples

Genetic Compatibility Test London – Carrier Screening for Couples

A Genetic Compatibility Test (GCT), also known as carrier screening, helps identify whether you and your partner carry the same inherited genetic conditions.

Most carriers are healthy and unaware. However, when both partners carry the same gene mutation, there is a risk of passing a serious condition to a child.
