Genetic testing has revolutionized healthcare, offering valuable insights into our health, ancestry, and potential risks for inherited conditions. Whether you’re considering testing for medical reasons or curiosity, understanding how it works and what it can reveal is essential.
What is Genetic Testing?
Genetic testing analyzes your DNA to identify variations or mutations that may impact your health. These tests can help detect inherited conditions, assess disease risks, and even provide personalized treatment options. Advances in genetic research have made testing more accessible and informative than ever before
Types of Genetic Tests
- Diagnostic Testing – Helps confirm or rule out specific genetic conditions.
- Carrier Screening – Determines if you carry genes for inherited conditions that could affect future generations.
- Predictive Testing – Assesses your risk for developing certain diseases later in life.
- Pharmacogenomic Testing – Helps determine how your body responds to certain medications for personalized treatment plans.
