Genetic testing is the analysis of chromosomes (DNA), proteins, and certain metabolites in order to detect heritable disease-related genotypes, mutations, phenotypes, or karyotypes for clinical purposes.. 1  It can provide information about a person's genes and chromosomes throughout life. Available types of testing include: 1  Cell-free fetal DNA (cffDNA) testing is a non-invasive (for the fetus) test. 2  Newborn screening: Newborn screening is used just after birth to identify genetic disorders that can be treated early in life. A blood sample is collected with a heel prick from the newborn 24â48 hours after birth and sent to the lab for analysis.
Genetic tests are done by analyzing small samples of blood or body tissues. They determine whether you, your partner, or your baby carry genes for certain inherited disorders. Genetic testing has developed enough so that doctors can often pinpoint missing or defective genes.
