What is Genetic Counseling?

Genetic counseling is a process that provides individuals with information and support regarding genetic conditions. It involves assessing family history, discussing the likelihood of inherited conditions, and interpreting genetic test results. Genetic counselors are trained professionals who specialize in genetics and can help patients make informed decisions about their health and family planning.

Key Components of Genetic Counseling

   Counselors gather detailed information about the patient's family medical history to identify patterns that may indicate a genetic condition.

   
   

2. Risk Evaluation

   Based on the family history and, if applicable, genetic testing, counselors evaluate the risk of developing or passing on genetic conditions.

   
   

3. Education

   Patients receive information about genetic conditions, including their causes, symptoms, and potential treatments. This education empowers patients to make informed choices.

   
   

4. Support

   Genetic counselors provide emotional support and guidance throughout the decision-making process, helping patients cope with the implications of genetic information.

   
   

5. Referral
