What exactly is genetic testing for? Is genetic testing useful?

1. Know whether you have inherited disease-causing genes.

People with a family history of cancer or polygenic genetic diseases are the most in need of genetic testing for early detection and prevention, and to avoid or delay the possibility of the disease.

2. Choose the right medicine.

Due to individual genetic differences, different people will react differently to foreign substances (such as drugs), so some patients may have drug allergies, redness, swelling and rashes when using normal doses of drugs.

Or when taking the same drug, some people think that it works, but some people not only do it not work, but also ***. Genetic testing helps to understand the genetic constitution through the determination of genes related to drug response and assists in the most likely drug response.

3. Provide the best basis for health risk management.

At present, many adverse environmental factors, such as air quality and pesticide pollution, plus bad lifestyle habits such as smoking, drinking, etc., will induce genetic mutations and cause diseases. Genetic testing can understand the tendency of each person to develop different diseases, and carry out comprehensive life adjustments or interventions to reduce the risk and delay the occurrence of diseases.

4. Auxiliary diagnosis:

Genetic testing is a disease diagnosis that detects mutated genes that cause hereditary diseases. At present, the most widely used basis is the detection of neonatal hereditary diseases, the diagnosis of genetic diseases and the auxiliary diagnosis of some common diseases.

5. Clinical diagnosis:

For people with initial symptoms, genetic testing can help to confirm the diagnosis clinically, and can make up for the functional defects caused by the susceptibility genes according to the carrying of susceptibility risk genes, so as to carry out corresponding ** and prevent further deterioration of the disease.

More than a dozen common cancers, as well as nearly 100 common diseases such as depression, diabetes, and Alzheimer's disease, can be tested through genetic testing to understand the risk of disease and carry out targeted prevention.

Modern people attach great importance to health, especially in the case of high incidence of cancer, many people are worried that they will have cancer, or the potential risk of cancer, so they plan to do a genetic test first, through high-tech means to understand whether there is a disease in their body. But at present, there are many people who regret doing genetic testing, so what's going on? Let's take a look.

People regret doing genetic testing, because there are many risks in doing genetic testing to detoxify, and in the United States, it is strictly forbidden for any company to pass genetic testing ** cancer service, and there will be many unfavorable factors after genetic testing. In addition, for most people, genetic testing is not necessary, because its test results may not be of reference value, but people will feel nervous and anxious because of the test results.

In addition, people regret genetic testing, mainly because the testing company may take the tester's gene to do some illegal things, the gene is like a person's ID card, everyone's gene is different, when their genes fall into the hands of others, let others slaughter, the other party takes their genes to do some illegal and harmful things, and individuals cannot stop it.

Therefore, it is recommended that people do not go for genetic testing, and if they want to know whether they have cancer, they can go directly to the hospital for relevant examinations, and there is no need to spend money on genetic testing.

1.If you have a better understanding of your child's dominant genes, you can train your child in a planned way.

2.Genetic testing is a technique that uses blood, other body fluids, or cells to detect DNA. Genetic testing can be used to diagnose diseases and can also be used to determine the risk of disease**.

3.Disease diagnosis is the use of genetic testing technology to detect mutated genes that cause hereditary diseases. At present, the most widely used genetic testing is the detection of neonatal hereditary diseases, the diagnosis of genetic diseases and the auxiliary diagnosis of some common diseases.

There are currently more than 1,000 genetic diseases that can be diagnosed by genetic testing. I wish you good health!
