Genetic testing involves carrying out a range of tests on DNA samples extracted from blood, saliva and other tissues. The DNA sample is then sent to the laboratory where scientists look for specific changes in the DNA. Genetic testing is an incredibly useful tool for identifying changes or mutations that could lead to genetic disease.The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder. Genetic testing allows us to be aware of certain health risks, make long-term beneficial health decisions but ultimately, encourage us to adopt a healthier and more balanced lifestyle.
A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes.
Yes, you need to. Physical examination and genetic testing are entirely different. A physical examination is solely for the purpose of diagnosis and treatment, detecting the presence of a disease after it has occurred. Genetic testing is able to assess a person's susceptibility to a disease before it has occurred and helps identify the condition that is likely to arise in the future. A genetic test is aimed at prevention against a specific disease or many diseases so that people can take steps to prevent or reduce risk.It is not uncommon that by the time a person is diagnosed with a certain disease, the detection result suggests a more severe case, especially in cancer. Genetic testing helps people discover genes that contribute to a disease or susceptibility genes early so that people can take measures to prevent the diseases by inhibiting the expression of those susceptibility genes. At the same time, genetic testing offers guidance to avoid potential health problems. Don't wait until it is too late. Health is wealth because if you are not careful enough, more money will be spent on your health. It's better to think ahead and take a genetic test.
A genome is an organism's complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome is contained in all cells that have a nucleus. Each person inherits a copy of genomic DNA from each parent.
