In principle, the sooner the better, because the sooner you know the greatest risk to your health, the sooner you can take preventive measures and be in a favorable position in prevention.
2. What is the basis and standard of testing?
The genes selected for testing items are closely related to the human body's ability to maintain health. The detected genes are published in the report, and the functions and functions of the selected genes are very clear, and anyone can query them through the authoritative American NCBI website; Protein encoded by the selected gene is dominant in maintaining various health abilities, and genes with unclear functions and little influence are excluded. The most important thing is the influence of the selected gene mutation on the body, which can be effectively adjusted by external intervention-changing one or more lifestyles and supplementing nutrition.
3. Is it necessary to do genetic testing without a family history of genetic diseases?
It is also very necessary for people who have no family history of genetic diseases to do this examination. The reason is that even if a person's family has no probands such as malignant tumor or coronary heart disease in the past, it does not mean that there are no bad genes in the family. Moreover, in today's society, affected by environmental pressure and labor intensity, as well as a large number of environmental pollution and the use of antibiotics, human living conditions are deteriorating, and these external stimuli may lead to deviations in human biological performance.
4. Is it necessary for people who are already ill to do genetic testing?
People who have been ill need to know whether their illness is related to heredity or purely environmental problems. This is an important reminder for your family and future generations. In addition, genetic testing can also know whether you have shortcomings in other abilities and whether there are other health risks, so it is necessary for the affected people to do testing.
5. If the elderly are old, is it necessary to do genetic testing? How old is it usually meaningful to do genetic testing before?
This depends on the requirements of the elderly and their families. If it is possible for people under 70 to be tested, the occurrence and course of diseases in the elderly are related to genes and environmental factors. After detecting the risk of illness, special care can be given to family members in the aspects of family care and nutritional supplement after aging, which can greatly delay the occurrence of senile diseases and reduce the economic and mental burden of families.
6. What should I do if I am detected as high risk?
The test results are high-risk, indicating that our innate prevention ability for this disease is weak. According to the advice of geneticists, we can carry out early screening in the test report, find lesions with non-invasive genetic testing in the early stage of the disease, or carry out non-invasive genetic physical examination regularly to prevent problems before they happen.
7. Is it reliable to collect DNA by oral sampling? Why not use blood?
There are exfoliated oral epithelial cells and leukocytes in salivary glands in saliva, which contain DNA and can be used for detection.
Blood, saliva, excrement, etc. They all contain DNA, but a needle is needed to collect blood. In order to create a non-invasive, painless, convenient and fast experience, no blood is needed. At the same time, the sampling package has undergone strict aseptic operation and is scientific and safe.
8. How long is the test result valid? Do you need to re-test in the future?
Because people's genes are innate, as a rule, it is enough to do genetic tests such as disease susceptibility, personality characteristics and talent once in a lifetime. However, with the development of the company's scientific research and the world's genetic research and the improvement of the understanding of genes, other genes will be found, and the types of detection will continue to expand at present, so new detection projects are needed in the future.
