genetic testing
Hereditary screening procedure
Genetic testing is the analysis of DNA, chromosomes, or proteins to detect inherited conditions, disease risks, or biological relationships.
Medical genetic testing screens for conditions like cystic fibrosis or predisposition to certain cancers.
The genetic testing revealed she carried the BRCA1 mutation.
Direct-to-consumer genetic testing has expanded into ancestry analysis and trait prediction, though results vary in reliability and interpretation.
