"In recent years Gulf countries have introduced mandatory premarital testing for genetic diseases including sickle cell anaemia, as well as infectious diseases such as hepatitis and HIV. In Qatar, counselling is required if a potential genetic problem is detected, though the couple are free to marry if they choose"
