2. The term "genetic testing" covers a range of techniques and can be defined as the analysis of human DNA, RNA, genes and/or chromosomes or the analysis of human proteins or certain metabolites, in the main purpose of detecting a hereditary genotype, a mutation. , phenotype or karyotype. Genetic testing is used as a healthcare tool to detect genetic variants associated with a specific disease or condition, as well as for non-clinical uses such as paternity testing and forensics. In clinical testing, genetic testing can be performed to determine the genetic cause of a disease, confirm a suspected diagnosis, predict future disease, detect when an individual might pass on a genetic mutation to their children, and predict response to treatment. They are also carried out to screen newborns, fetuses or embryos used in in vitro fertilization for genetic abnormalities.3. The variety of genetic tests has expanded significantly and become increasingly accessible thanks to advances in science and technology. Genetic testing can have significant consequences on an individual's health, influencing their decision to make difficult and life-changing decisions about high-risk health issues, such as undergoing a preventative mastectomy if tested for a gene mutation. BRCA gene. Although there is regulation and oversight aimed at promoting the quality of laboratories involved in clinical testing, there is a need to customize and improve regulations specific to clinical genetic testing. This article focuses on genetic testing offered in a clinical setting, used for disease diagnosis, predictive genetic testing often performed before clinical signs of the disease or condition appear, and DNA variant testing hereditary factors that predict response profile..... . middle of paper ....... Preparing the family for health care23. Laboratory personnel should be trained and educated to have a thorough knowledge of genetic principles, technologies used, limitations of tests used, appropriate understanding of the clinical implication of test results and how to communicate this information. Health professionals who perform the tests must be trained and have the experience to order genetic tests and interpret the results. This includes the nursing family who interacts with patients and their families on a daily basis. Additionally, there is a need to train more genetic counselors to ensure that effective pre- and post-test counseling can be provided to patients. Genetic Testing Advisory Committee will make recommendations to expand the health care family's knowledge and capacity in genetic testing..
