Genetic screening is a comprehensive DNA analysis that allows the identification of hereditary diseases, genetic mutations, predisposition to various pathologies, and metabolic characteristics. Screening is used for prevention, early diagnosis, and personalized medicine.
When is genetic screening required?
During pregnancy planning to exclude the risk of transmitting hereditary diseases to a child. In the diagnosis of genetic mutations and predisposition to oncological, cardiovascular, endocrine, and neurological diseases. To identify rare genetic disorders, metabolic abnormalities, and individual drug response. When examining families with a high prevalence of hereditary diseases and for the prevention of age-related pathologies.
Types of genetic screening
- Neonatal screening – detection of congenital genetic diseases in newborns.
- Prenatal screening – diagnosis of chromosomal abnormalities in the fetus (Down syndrome, Edwards syndrome, Patau syndrome).
- Oncogenetic screening – assessment of cancer risk (breast, ovarian, prostate, colorectal cancer).
- Cardiogenetic screening – identification of predisposition to hypertension, myocardial infarction, and stroke.
- Pharmacogenetics – determination of individual response to medications.
How is the examination performed?
A buccal swab (cheek epithelium) or venous blood is used for analysis. Genetic information remains unchanged throughout life; therefore, the test is performed once. The results are provided in the form of a report with a physician’s recommendations.
