Genetic Counselling

Genetic counselling is a specialised medical service aimed at helping individuals and families understand the implications of inherited genetic conditions. It involves the assessment of personal and family medical history, education about genetic conditions, and personalised guidance in decision-making related to genetic testing and management.It is conducted by trained genetic counsellors or healthcare professionals specialising in genetics.
Genetic counselling provides vital support to individuals seeking information about their genetic health, empowering them to make informed choices about their medical care and family planning.

2. Explains Genetic Testing Options: Discusses available tests to assess genetic risks, including their benefits, limitations, and potential outcomes.
3. Interprets Genetic Test Results: Helps patients understand the significance of the results and their impact on health and family.
4. Provides Emotional and Psychological Support: Offers reassurance and addresses concerns about genetic risks and diagnoses.
5. Guides Future Decisions: Assists in making informed decisions about healthcare, lifestyle, and family planning.
