The American College of Obstetricians and Gynecologists recommends all people thinking of becoming pregnant be tested to see if they have<unk> . Genetic counseling and genetic testing are recommended for families who carry a<unk>  trait. A screening policy exists in Cyprus to reduce the rate of<unk> , which, since the program's implementation in the 1970s (which also includes prenatal screening and abortion), has reduced the number of children born with the disease from one of every 158 births to almost zero. Greece also has a screening program to identify people who are carriers. In Iran as a premarital screening, the man's red cell indices are checked first. If he has microcytosis (mean cell hemoglobin < 27 pg or mean red cell volume < 80 fl), the woman is tested. When both are microcytic, their hemoglobin A2 concentrations are measured. If both have a concentration above 3.5% (diagnostic of<unk>  trait) they are referred to the local designated health post for genetic counseling. Large scale awareness campaigns are being organized in India both by government and non-government organizations in favor of voluntary premarital screening to detect carriers of<unk>  and marriage between both carriers is strongly discouraged.
