Carrier screening(AssuriT-CS)
—
Most children with monogenic genetic diseases do not show structural malformations during embryonic development, which are not easily detected by imaging, and many recessive genetic diseases often do not have a clear family history of inheritance; therefore, effective prevention and control of monogenic genetic diseases cannot be achieved by conventional means of obstetrical testing, and extended carrier screening is recommended by domestic and international clinical guidelines and experts' consensus as an effective measure for the prevention and control of birth defects in monogenic genetic diseases.
