What are the benefits of genetic testing

A gene is a functional segment on the DNA molecule, the basic unit of genetic information, and the most fundamental factor that determines all living species. Genetic testing is the technique of testing DNA through blood, other body fluids, or cells. Genetic testing can diagnose diseases and can also be used for disease risk prediction. Here's what you need to know about genetic testing.

2 The significance of genetic testing 1, predictive medicine. The risk of disease can be accurately predicted in the period of health and sub-health.

2, disease prevention. Disease = internal + external causes. Through the understanding of internal causes, the influence of external causes can be effectively avoided, thus reducing the risk of disease.

3. Health management. Through genetic testing, we know that we have certain disease susceptibility genes, so we can take the initiative to improve our environment and living habits, and do a good job of managing our health.

4, personalized medical services. Through genetic testing, we are prompted which drugs should be used with caution, which not only greatly reduces unnecessary medical expenditures and improves therapeutic efficacy, but also avoids causing greater harm to the human body.

3Gene testing technologyNew Generation Sequencing (NGS) mainly includes whole-genome resequencing (whole-genomesequencing, WGS), whole-exome sequencing (whole-exomesequencing, WES) and Targetedregionssequencing ( Targetedregionssequencing (TRS). Overall, NGS technology has the advantages of high throughput, short time, high accuracy and rich information, which enables geneticists to precisely localize genes of interest in a short time.

4Genetic test costSome genetic testing organizations provide genetic tests that require tens of thousands of dollars, while some online stores can do a test for a few hundred dollars, which seems to be the same test program price difference is very large. At present, the general price of genetic testing products of formal institutions is based on the test project to billing, a single genetic test requires a few hundred dollars, including more items of the package will reach thousands or even tens of thousands of dollars. However, there are some genetic testing companies in the market that do not have the appropriate service qualifications, taking advantage of the general public's lack of understanding of genetic science and technology information, launching testing packages with inflated prices to earn profits.

5 genetic testing organizations to choose 1, genetic testing organizations have a strong technical background;

2, genetic testing organizations have a laboratory certified by the standards;

3, genetic testing organizations have a complete database of genes and disease associations;

4, genetic testing organizations to establish a professional and accurate mathematical models;

5, gene The genetic testing program is tailored to the characteristics of the Chinese population;

6. The genetic testing program is supported by comprehensive post-test services, and provides personalized health guidance and consultation.

6 non-invasive prenatal genetic testing in fact non-invasive prenatal genetic testing was once called off. Non-invasive prenatal genetic testing is, after all, a check of the genetic examination methods, rumors of non-invasive prenatal genetic testing was once called off the topic has never been broken. Because the relevant state departments have not been able to make reasonable control on non-invasive prenatal genetic testing, so non-invasive prenatal genetic testing was stopped for half a year, but then after the State Food and Drug Administration, after review, approved UWG's two second-generation gene sequencers and test kits to be used in "non-invasive prenatal genetic testing", which is to detect Down's syndrome in pregnant women and to test the genes of women with Down's syndrome. That is, for the maternal detection of Down syndrome and other genetic diseases risk, in order to avoid birth defects in newborns, and the current non-invasive prenatal genetic testing is considered to be a reboot state, many hospitals also have non-invasive prenatal genetic testing mechanism.

7 children's genetic testing a biology doctor said, for children's athletic talent genetic testing or have a certain scientific basis, "for example, an athlete's explosive force is different from the norm, the content of its muscle proteins and so on, it must also be different from the norm, this muscle development genes by technical means can still be detected! ". As for the detection of children's musical talent, painting talent, etc., because the biological basis of such functions is still very unclear, so "children's talent genetic testing is not reliable".

From a practical point of view, making predictions based on traditional 'such family origins' + children's 'natural hobbies' should be more accurate and cost nothing.

If the parents are specialized in this area, then the probability of the child getting a genetic 'advantage' is naturally higher, and more importantly, the child grows up with a lot of exposure - the environment and genetics interplay is naturally stronger. If the child grows up showing a strong interest and aptitude for this area of expertise, then the result of the genotype-environment interplay is made real in the 'phenotype'.

8 Cancer Genetic Testing Genetic testing of tumor cells can help your primary care physician develop a personalized treatment plan for you. Genetic testing can determine your cancer genetic profile and then match your genetic profile to published cancer treatment options through evidence-based medicine. Who deserves cancer genetic testing?

1. The person is at personal or familial risk for hereditary cancer.

2. The test results give a clear explanation for the presence of a cancer-causing gene.

3. The test results can help the person with future medical care.

Experts suggest that it is worthwhile to have a genetic test for cancer when all three of the above are met.
