Where can I get genetic testing?

Genetic testing is a type of genetic testing that predicts whether a person is at high risk of developing a common disease through the sequence of genes. Genetic testing.

It can tell us the critical point of various diseases in the individual.

For example, the height of various diseases can be resisted, etc., so how to do genetic testing? You can do it.

Genetic testing process:

Client registration: The subject fills out the "Informed Consent Form".

and the "Information Registration Form", which will be submitted to the genetic testing institution to establish a health file.

Sample collection: Usually a blood sample, no special requirements, no fasting is required.

Specimen collection is done by specialized medical institutions.

After receiving the sample, the genetic testing institution will complete the sample testing, result analysis, and report preparation. And the test report will be delivered to the examinee.

Report interpretation: After the customer receives the report, the testing institution will provide the report interpretation, and provide personalized healthy life guidance and suggestions in many aspects such as reasonable diet, appropriate exercise mode, good psychological state, social environment, targeted regular physical examination, safe medication and targeted medical treatment according to the results of genetic testing.

Genetic testing is possible.

At present, more hospitals or physical examination centers have carried out genetic testing projects, you can choose the right hospital for yourself according to your own situation, in addition to considering the service and environment of the hospital or physical examination institution and the best aspects. It is also necessary to select senior experts to conduct the examination to ensure the accuracy of the inspection results.

Diseases are the result of the combined action of congenital genetic endowment and acquired external factors, and almost all diseases are related to genes, and in some cases genes have mutations, resulting in human dysfunction and deviation from the standard state of normal physiological functions.

Therefore, genetic testing can be done to prevent the occurrence of diseases as soon as possible.

For genetic testing, you can generally choose the local provincial public tertiary hospital, which can basically do genetic testing, and the accuracy is relatively high. The cost of genetic testing may be about 5,000 yuan, and the charging standard of each hospital may be different.

There are quite a few places where genetic testing can be done, so you should choose a regular place. I went to Shenzhen Shengjing Gene for genetic testing, and the service was very good.

"Prepare for a rainy day" can we go to ** to do genetic testing?

There are only three.

1. Hong Kong Zentrogene Laboratory.

It is a veteran DNA biotechnology genetic testing institution, a registered authoritative genetic testing appointment agency approved by the Hong Kong ** and the Department of Health, and an authorized designated genetic testing referral service reception center, and the only outstanding medical integrity institution in the industry in Hong Kong for five consecutive years.

2. Hong Kong Tag Biotechnology****.

Located in Kowloon Bay, Hong Kong, Dayago Biotech is a member of the Hong Kong Biotechnology Association. It is a well-established laboratory company in Hong Kong that focuses on the application of molecular diagnostic technology to clinical testing services. It is the first company in Hong Kong to provide DNA genetic testing services.

3. Hong Kong Precision Genomics Laboratory.

Located at 17 Lok Mun Street, Fanling, New Territories, Hong Kong, the Hong Kong Precision Genomics Laboratory is undoubtedly a new addition to the genetic testing industry in Hong Kong compared to established laboratories such as ARCO.

To be tested by the four major laboratories in Hong Kong, the following criteria must be met:

1. The gestational age must be confirmed by B ultrasound to be greater than 7 weeks and the embryo diameter is greater than 10mm.

2. No male fetus has been born within one year.

No major surgery, blood transfusion, organ transplant, or miscarriage for months.

4. The common blood type is A, B, AB or O type (Rh-negative panda blood is also effective).

5. Natural conception, non-IVF.

Genetic testing is mainly done through blood drawing, and as for the rest, it is done by the hospital, not the patient. For patients, if they want to do genetic testing, they generally need to go to the relevant departments of the hospital**, and then they will open a genetic test form, and then go to the hospital's laboratory department to draw blood for examination, and the rest is to wait for the results. The time it takes to get results depends on how busy the hospital is, and the cost of testing varies.

Because it depends on the purpose of the individual's genetic monitoring, some only test for specific genes, and some need to do whole genetic monitoring. The cost is about 2,000 yuan, and the expensive is tens of thousands of yuan. In short, it needs to be judged in combination with the individual's situation.

In general, there are three genetic testing methods: biochemical testing, chromosomal analysis, and DNA analysis.

Biochemical testing is the chemical testing of a sample of blood, urine, amniotic fluid, or amniotic cells to check for the presence of the protein or substance in question and to determine whether there is a genetic defect. It is used to diagnose a genetic defect caused by an imbalance of proteins that maintain the normal functioning of the body, usually by testing the protein content. It can also be used to diagnose phenylketonuria, etc.

Chromosome analysis directly detects abnormalities in the number and structure of chromosomes, rather than checking for mutations or abnormalities in a gene on a chromosome. It is usually used to diagnose abnormalities in the fetus. A common chromosomal abnormality is an extra chromosome, and the cells used for the test are obtained from a blood sample or, in the case of a fetus, by amniocentesis or chorionic villus sampling.

It is stained to make the chromosomes stand out, and then a high-powered microscope is used to see if there are any abnormalities.

DNA analysis is mainly used to identify genetic diseases caused by a single gene abnormality, such as Huntington's disease. The cells analyzed for DNA analysis are derived from blood or fetal cells.

Who is genetic testing suitable for?

Enben Genomics Help Center What is genetic testing? What is genetic testing used for?

Genetic testing is suitable for everyone and can help you understand the past and predict the future. If possible, it is necessary for everyone to have a genetic test.

Genetic testing can accurately obtain information about each person's ancestry, disease risk, genetic disease risk, drug efficacy and contraindications, personal characteristics, dietary and nutritional needs, exercise and fitness, and many other aspects, helping us understand our strengths, potentials, and health risks, so that we can not only target but also plan ahead.

People with a family history of genetic diseases and chronic diseases, people who have been in a polluted environment and radiation environment for a long time, and sub-healthy people should do genetic testing as soon as possible to know their current risk factors and find the right coping plan.

How to do genetic testing, do I need to draw bone marrow? The answer from the experts is very simple.

Genetic testing generally uses samples such as saliva and blood to extract genetic material and genetic material, analyze the sequence of these substances, and then obtain the patient's disease status after decoding. Although children and parents have some of the same genes, they are also different. Therefore, if you want to know the cause of your child's illness, Jiaxue Gene's recommendation is to check the child's genes as the first choice.

If there is no sample of the child, it can also be found through the genetics of the parents. However, it cannot be detected by general genetic testing, and it is necessary to use the gene decoding technology of whole exons and whole genes, and use the database of "Human Gene Sequence Changes and Human Disease Characterization" to find out.

Genetic testing sampling methods and processes.

There are 2 sampling methods, each described below).

1) Sampling and testing methods for oral mucosa.

Many testing units use the oral mucosal exfoliated cell sample collection method, and the collection procedure is as follows:

Oral hygiene: Rinse your mouth with water once or twice.

Pre-harvest preparation: Take out the No. 1 tube (flat bottom) from the box, shake it up and down lightly, and make all the normal saline deposited at the bottom of the tube. Unscrew the lid and place the tube on the table for later use.

Scrape cells: take out the oral mucosa scrape, reach into the mouth, stick the toothed part of the head of the scrape on one side of the mouth, the cheek part on the inside of the mouth is located between the upper and lower teeth, scrape the oral mucosa more than ten times with a little force (equivalent to the force of brushing) in the front and back directions, and then scrape the oral mucosa on the other side with the other side of the head of the scraper (do not need to turn the spatula), scrape more than ten times.

Collect the cells: Wash the mucosal cells into the water by quickly dipping a spatula into the saline of tube 1 and agitation. Lift the spatula away from the water, leave it for a moment and shake the spatula so that all the water on the scoop drip into the tube. At this time, it can be seen that the saline solution changes from clear to turbid.

Fixed cells: Take out tube No. 2 and shake it gently so that all the solution is deposited at the bottom of the tube. Pour all the solution in tube No. 1 into tube No. 2, cover and tighten the screw cap of tube No. 2, and shake vigorously up and down 10 times.

Mailing samples: Place tube No. 2 in a paper bag in a ziplock bag and send the ziplock bag tightly for testing.

2) Saliva sampling and testing methods.

At present, a relatively new genetic sample collection method - saliva sampling detection method has emerged, which is more convenient and faster, and realizes non-invasive collection, and the detection effect is the same as that of oral mucosal extraction.

The genetic sample collection process is as follows:

1. Oral cleaning: explain the sampling process and precautions, require customers to rinse their mouths with water, and do not eat, drink, smoke, drink or chew gum within half an hour.

2. Pre-harvest preparation: Wear disposable medical gloves (using hospital standard wearing methods and procedures), open the collection box and prepare for sampling. Remove the tube from the box, remove the plug cap, and insert the tube into the funnel.

4. Take saliva: collect saliva into the sampling tube through the sampling funnel until the position indicated on the label on the sampling tube.

Note: To ensure that the actual saliva volume reaches the scale mark, the foam in the upper layer is not included, and the saliva sampling process must be completed within half an hour.

5. Save the sample: take out the lid of the cup from the box, the lid contains the fixative solution, and screw the lid in the clockwise direction of the sampling funnel. After confirming that the lid of the cup is tightened, invert it 10 times to mix the saliva and fixative solution thoroughly, keep the lid of the cup on top, and place the sampling tube vertically for 5 minutes.

Keep the sampling tube vertical, pull out the sampling funnel, cover the sampling tube tightly with the plug cap, and mix upside down 10 times.

Note: The fixative solution in the lid of the cup should be clear, colorless and transparent, if it is cloudy, please discard. Please do not tear the plastic film inside the lid with your hands.

6. Mailing samples: discard the sampling funnel and the lid of the sampling cup, put the sampling tube and the completed information into the paper bag of the ziplock bag, and seal the ziplock bag tightly and send it to the test.
