Genetic testing is becoming increasingly more prevalent as progress in biotechnology are being made. The term "genetic testing" refers to the use of a test which looks for changes in a person's genes or arrangement of particular proteins (National Human Genome Research Institute [NHGRI], 2014). Genes are decoded and every letter of the DNA sequence could be determined. There are a number of uses for this kind of testing, for example, but not restricted to, diagnosis of rare genetic disorders, hazard diagnosis for hereditary ailments, and determining appropriate treatments for patients. There are 3 kinds of genetic tests: gene tests, which look at quite short lengths of DNA or RNA, chromosomal tests, which analyze whole chromosomes, and chemical tests, which examine protein levels and/or enzyme activities (NHGRI, 2014). Genetic testing assesses DNA or RNA sequences for mutations and adjustments that could possibly bring about a individual's health conditions. Concerning genetic testing techniques, gene tests are often performed on samples of blood or other bodily fluids taken from the patient to search for genes like the ones that are missing fragments, have significantly altered subunits, or are dormant. The blood is drawn, processed in the lab to extract DNA, and the DNA is sheared into fragments to be sequenced (Public Broadcasting Service [PBS], 2012). Kinds of chromosomal tests are karyotyping, which provides an image of all of a individual's chromosomes so that any changes in number or structure can be identified, and fluorescent in situ hybridization (FISH) analysis, which utilizes fluorescent DNA probes to discover missing or extra copies of chromosomes (NHGRI, 2014). Karyotyping may be used for prenatal screening on embryosnonetheless, there's still some debate as to it...
