What are the benefits of human genetic testing

Genetic testing is a technique that tests DNA through blood, other body fluids, or cells.

Genetic testing can be used to diagnose diseases and can also be used to determine the risk of disease**. 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.

In recent years, it has been very exciting to carry out the development of sexual genetic testing. Genetic testing technology is used to detect the risk of disease before it occurs, so as to prevent it early or take effective interventions. There are already more than 20 diseases that can be treated with genetic testing**.

In the test, the person's genes are extracted from the blood or other cells. Then, primers and PCR technology that can identify genes that may have mutations are used to replicate these genes many times, and mutant gene probe methods, enzyme digestion methods, gene sequence detection methods, etc. with special markers are used to determine whether there are mutations or sensitive genotypes in these genes.

At present, the main methods of genetic detection are: fluorescence quantitative PCR, gene chip, liquid biochip and microfluidic technology.

Central Concord Gene

Real genetic testing costs thousands of yuan for one site, and there are many types of cancer, and if you want to test them all, the cost is quite high. At present, some so-called genetic tests are not real genetic tests, but are through the detection of some physiological indicators, under the banner of genetic testing.

Correct selection of drugs to avoid drug abuse and adverse drug reactions Due to individual genetic differences, different people will react differently to foreign substances, so some patients may have drug allergies, redness, swelling and rashes when using normal doses of drugs. According to the results of genetic testing, a specific program can be formulated to scientifically guide the use of drugs and avoid drug toxicity and side effects.

Clinical significance:1For the diagnosis of diseases such as the diagnosis of Mycobacterium tuberculosis infection, previously mainly relied on sputum, stool or blood culture, the whole test process needs to take more than two weeks, using the method of genetic diagnosis, not only the sensitivity is greatly improved, but also the results can be obtained in a short time.

2.Understand whether you have the pathogenic genes of familial diseases, ** The risk data confirm that 10% and 15% of cancers are related to genetics, and many diseases such as diabetes and cardiovascular and cerebrovascular diseases are related to genetic factors.

For example, people with cancer or polygenic genetic diseases (such as Alzheimer's disease, hypertension, diabetes, etc.) can find out the genetic genes that cause the disease, and then they can make targeted lifestyle adjustments to prevent or delay the occurrence of diseases.

There is an early diagnosis of these genetic defects.

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.

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.

Genetic testing refers to taking the blood and oral mucosal cells of the tested person, extracting and amplifying their genetic information, and testing the genetic information of the DNA molecules in the cells of the tested person through gene chip and other technologies, and analyzing themDisease risk, medication safety, nutritional metabolism

oneDisease risk

Genetic testing can predict the risk of high-incidence diseases and detect whether they carry congenital inherited disease genes, which can help cancer patients carry out personalized and personalized medical treatment. It mainly involves reproductive reproduction, including non-invasive prenatal screening and preimplantation genetic diagnosis PGS PGD, genetic disease screening, hereditary tumor genetic testing, etc.

It is to interpret the genetic code related to drug response, and the degree of adverse reactions of patients to different drugs plays a certain guiding role in clinical use. Referring to the results of genetic testing, doctors can propose individualized medication plans suitable for each patient in terms of drug selection, dose control and combination of drugs when prescribing, so as to improve drug efficacy, reduce drug toxicity and reduce medical costs. Let patients spend the shortest time, the least money, to achieve the best results.

FourAthletic potential

The items of sports genetic testing mainly include endurance, explosiveness, balance and fracture injury risk and other human exercise quality tests. During exercise, a reasonable exercise plan can be formulated according to the individual's physical fitness, and the risk of sports injuries can be effectively reduced.

FiveAncestry analysis

Ancestry analysis is a popular test item in consumer-grade genetic testing, and ancestry analysis is theoretically feasible but does not have much value in the sense of practical guidance.

The first two are mainly used in clinical practice, while the last three are mainly consumer-grade genetic testing.

Genetic testing can only be used as an adjunct**, and there is no basis for genetic testing to prevent disease.

There are many functions, mainly used in medicine, for example, pregnant mothers can use pre-pregnancy genetic testing to assess the risk of the next generation of disease and prevent it in advance, cancer patients can use targeted drugs through genetic testing, and many examinations during pregnancy are related to genes.

Genetic testing is used for many purposes, mainly for disease screening and diagnosis, adjuvant medication, and early prevention of disease risks.

For people with cancer: look for **, find targeted drugs, and prolong the survival of patients.

Healthy people: ** risk of disease, can also guide fertility.

The main use of genetic testing is for eugenics.

That is, if there is a hereditary disease in the family, genetic testing is required, and when giving birth to offspring, it is necessary to choose not to have children with disease-causing genes, so as to ensure the health of offspring.

At present, the third generation of IVF technology has been able to screen fertilized eggs with genetic diseases. Thus guaranteeing the birth of healthy children.

Now that it is market-oriented, it is purely for your money to do genetic testing for some patients who do not have fertility requirements, and even for ordinary diseases.

1.Genetic testing can lead to ** disease. 2.

Genetic testing is the first step in the use of targeted drugs**. 3.Meals can be guided.

4.Provide a basis for personalized medication. 5.

It can effectively avoid clinical misdiagnosis. 6.Helps to make good lifestyle choices.

We recommend that you use genetic testing technology to detect the risk of disease before it occurs, prevent it early, or take effective interventions.

If you get the disease, you can use genetic testing to detect whether it is the same as the gene of a certain disease, and you can confirm whether it is the disease. Get the right medicine. It can also be used to test for familial genetic disorders.

Genetic testing (GeneticTest) is based on chromosome structure, DNA sequence, DNA variation loci or gene expression degree, providing the basis for the subject and medical researchers to evaluate some diseases, constitutions or personal characteristics related to genetic inheritance Each person's DNA genes are unique and personalized information, resulting in each person's congenital constitution, health status, and characteristics are different

In 2008, Time magazine named this revolutionary technology the best innovation of 2008

Genetic testing is to find the "genetic landmines" hidden in your body before the body is sick, and it is a test for diseases that may occur in your future, so that you have enough time to find your best health care methods and lifestyles according to scientific judgments, so as to avoid and prevent the occurrence of major diseases to the greatest extent.

Genetic testing can be used to screen for inherited disease genes carried by both men and women, as well as for genetic diseases carried by newborns.

In China, the most common monogenic genetic diseases include hemophilia A, hemophilia B, hereditary deafness, spinal muscular atrophy, phenylketonuria, Wilson's disease, glycogen storage disease, thalassemia, etc.

At present, genetic testing products using high-throughput sequencing methods can detect the genes of the next generation of recessive diseases that may be inherited by both men and women, as well as other serious recessive diseases.

The so-called genetic testing is to extract cells, and then through specific technology and equipment to detect genetic information such as DNA molecules in the cells of the tested, love gene is PCR technology to analyze the situation of various disease susceptibility genes contained in him, so that people can understand their genetic information in a timely manner, ** the risk of disease in the body, so as to improve their living environment and living habits, so that they can live clearly. Genetic testing can find the "genetic landmines" hidden in your body when your body is not diseased.

Benefits of genetic testing.

1. Health management: through genetic testing, if you know that you have a certain disease susceptibility gene, you can take the initiative to improve the environment and living habits, and do a good job in your own health management;

2. Personalized medical services: through genetic testing, we are reminded which drugs should be used with caution, which not only greatly reduces unnecessary medical expenditures, improves the efficacy, but also avoids greater harm to the human body;

3. Medicine: The risk of disease can be accurate during healthy and sub-health periods;

4. Disease prevention: internal and external causes of disease. By understanding the internal factors, the influence of external factors can be effectively avoided, and the risk of disease can be reduced.

Not doing genetic testing is like walking at night, never knowing the potholes in the dark, and when you find it, you have already fallen into it; Doing genetic testing is equivalent to illuminating the way to the future; For example, whether a person can drink alcohol (alcohol metabolism genetic testing); Another example is that some people do not know that they have a high risk of genetic tumors and so on.

The significance of genetic testing is as follows:

A: Help**Disease RiskExcept for trauma, all diseases are related to genes. By detecting the genes associated with the disease, the "disease mines" in the body can be detected and predicted at an early stage, so as to eliminate the fuse of the mines**.

Disease susceptibility gene testing is like an accurate "weather forecast" of health status, allowing people to detect disease susceptibility genes early, prevent them early, and prevent them early. Disease is no longer passive**, but very accurate and targeted prevention. Help choose the right medicationThe same drug, different people take it with different effects; Different drugs for the same disease, the same person eats, the effect is not the same, this is because different people have different metabolic abilities for different drugs.

Pharmacogenetic testing derives an individual's metabolism of hundreds of drugs through gene sequence analysis of loci related to drug metabolism. Doctors can refer to the patient's genetic results and disease conditions, judge the possible drug reaction, use the appropriate drug variety and dosage for the patient, avoid or reduce the use of unsuitable drugs and inappropriate dosage, resulting in re-injury to the patient's body, ensure the safety of the drug, and improve the best effect. When a healthy couple carries the same disease-causing gene and passes this gene to their child at the same time, then misfortune befalls her.

Genetic testing for monogenic genetic diseases can scientifically guide eugenics and parenting by detecting whether both husband and wife carry relevant pathogenic genes, avoid the birth of defective children, and reduce the economic burden on families. Everyone has their own hobbies and habits, such as drinking tea, coffee, smoking, drinking, etc. Due to genetic factors and different genes in the body, each person's tolerance and reaction to tobacco, alcohol, tea, coffee, etc. are also different.

Genetic testing can be an option to live a healthy lifestyle and avoid unnecessary harm.
