How to test for Helicobacter pylori? How is Helicobacter pylori detected?

Helicobacter pylori is a very powerful microorganism, it is contagious, he parasitizes in the human stomach, for Helicobacter pylori infection is already a very common bacterial infection, Helicobacter pylori and gastric ulcer, duodenal ulcer and gastric cancer are closely related, so how to detect Helicobacter pylori? Let's take a look.

There are four main detection methods for Helicobacter pylori:

The first is to detect by serum, but it is not often used in hospitals now, because after the patient's **, the ghost bacteria antibody in the blood will still exist for one to two years, and there may be false positives.

The second is the breath test of C13 and C14, which can indirectly detect the fungus antigen, but C14 is polluting to the human body and the environment, and the human body will not be degraded after eating isotopes, which is not suitable for pregnant women and children. C13 is an upgraded version of C14, which removes the contamination of C14, but requires the consumption of the substrate labeled with relative C13, and the sensitivity and specificity are relatively high.

Third, the hospital will still use gastroscopy and gastric mucosa for biopsy, which is an invasive method, and many people are more reluctant to use this method. However, its pathological section has a high degree of accuracy and comparison, and the accuracy of chemical reaction is relatively low, and there are areas with small lesions that are easy to miss. It is more rejected by many patients, and its examination cost is relatively high, which is not suitable for general examination.

Fourth, the saliva test method indirectly detects the phloric antigen, and the sensitivity, specificity and pertinence of urease are measured, which is simple, safe and fast. It also fills the gap in the detection of oral Helicobacter pylori, which is very suitable for initial examination and reexamination.

The above are the four methods of Helicobacter pylori detection, invasive methods may be difficult for many patients to accept, non-invasive methods will be easy to accept, the best detection methods for Helicobacter pylori are C13 and C14 urea breath test, this method is the simplest and best detection method.

There are many ways. The most direct is the C14 breath test, give you a specimen box, exhale it, and the inspector will guide you then; The second is to directly take the specimen through gastroscopy for testing; There are also those that are checked by stool; Wait, there are many ways to check, go to the digestive specialist to see.

You need to take a blood test, and you can go to the hospital and pay for it.

How should I be tested for H. pylori?

Introduction: Helicobacter pylori, this kind of cell that many people have heard of, is a bacterium inside the stomach, this bacterium has a variety of shapes, sometimes spiral-shaped, sometimes rod-shaped, so how is Helicobacter pylori measured and how is it caused? The following is a collection of information about Helicobacter pylori, if you are interested, you can take a look.

1. The detection method is a kind of bacteria that parasitizes the stomach and intestines and has a certain damage to the gastric mucosa. It can be checked by the following methods, first of all, you can directly do gastroscopy, in this by swallowing a urea capsule and blowing a breath to check this method, called breath test, through blood testing, Helicobacter pylori antibody to determine whether the antibody is negative or positive, if the antibody is positive, it means that there is a bacterial infection in the body, by testing the stool to see if it contains Helicobacter pylori antibody, swallowing urea capsule is the most widely used clinical method so far, and its results are also very reliable, Drawing blood and testing stool to determine antibodies only indicates a history of infection, not a current infection. <>

Second, the mode of transmission is mainly in the human stomach, therefore, when the internal mucosa is shed, Helicobacter pylori will fall off with the shedding mucosa, and it will be discharged together with urine and feces through the stomach and intestines, and the urine and feces may affect the surrounding food and water, and if you accidentally eat contaminated food and water, you will be infected by transmission. It can also be transmitted through saliva and other means, as long as one of them is infected by Helicobacter pylori and does not use chopsticks during meals, there is a risk of infection. Helicobacter pylori may be present in gastric juice, so when a person vomits with a popular bacilli, the internal virus will be transmitted to healthy people with vomit, especially in the acute phase, and it is often transmitted through vomit.

3. Symptoms are manifested as satiety, discomfort or pain after eating, often accompanied by heartburn and loss of appetite, and some patients may have repeated severe abdominal pain. If such symptoms are found, it is necessary to go to the hospital in time**, which has its effect on such diseases**.

At this time, you can go to a special hospital for testing, and you can also take a gastroscopy, and then you can also test by blood routine, and once there is nausea or nausea, vomiting or discomfort, you must go to the hospital for examination in time.

It can be detected by a carbon-13 or carbon-14 breath test, or by gastroscopy, blood Helicobacter pylori antibody test, and Helicobacter pylori antigen test.

Direct gastroscopy, by taking a urea capsule and then blowing a breath to check, breath test by blood drawing, through a stool test.

There are many ways to detect Helicobacter pylori, which can generally be divided into two categories: one is invasive Helicobacter pylori detection, and the other is non-invasive, which includes gastroscopy to take a piece of tissue for rapid urease detection, which is a detection method, and then send the tissue to the pathology department for special staining, which is also invasive. Then you can grow the bacteria, and if you can grow Helicobacter pylori, of course you can diagnose it, which is a bacterium that is infected with Helicobacter pylori.

The examination methods of Helicobacter pylori are divided into invasive examination and non-invasive examination, and invasive examination includes gastroscopic pathological examination, rapid urease examination, and Helicobacter pylori bacterial culture examination; The most commonly used non-invasive tests are carbon-13 and carbon-14 insufflation tests, in addition to monoclonal antigen detection of stool, Helicobacter pylori antibody detection, etc.; Different hospitals use different methods, but most of the methods used by hospitals are specific and fast, such as feeling stomach discomfort, you should go to a large hospital for Helicobacter pylori infection test, so as to take medication as soon as possible, and remove Helicobacter pylori from the digestive tract as soon as possible to prevent the development of serious stomach diseases.

Testing for Helicobacter pylori is simple and convenient. Go to the gastroenterology department of the hospital, use a measuring instrument, put it on the mouth, blow hard, and then come out a piece of lesion soil, the darker the picture, the heavier, and the no color means that there is no Helicobacter pylori lesion.

There are many methods for diagnosing H. pylori infection, such as biopsy, isolation and culture of H. pylori, rapid urease test, urea breath test, urine ammonia excretion test, serological test, and polymerase chain reaction. Different hospitals take different approaches.

If the Helicobacter pylori officer wants to do a test, he can do that blowing test, which is done by inhaling that kind of carbon.

Helicobacter pylori can be detected by going to the hospital and blowing an instrument.

Detection of Helicobacter pylori: 1. Non-invasive method: Immunological method to clear the HP antibody.

There are a variety of detection methods, but it is recognized that enzyme-linked immunosorbent assay and western blot test are superior, the advantage is that the specificity is high, close to 100%, and can be quantitatively analyzed, the disadvantage is that it cannot distinguish between previously infected and current epidemic patients, and is mainly suitable for epidemiological investigation. Urea breath test. The principle is that HP produces urease in the body, and after the urea labeled with 13C or 14C is taken by the subject, it is decomposed to produce carbon dioxide labeled with isotopes, and the breath specimen is collected, and the labeled carbon dioxide is detected with a liquid scintillation counter or a gas nuclear mass spectrometer, which is extremely sensitive, quantitative, and the patient has no spasms, and the method is simple and fast, and it is very reliable for detecting whether HP is the best.

Due to the small amount of radioactive materials in 14C, the 13C urea breath test is currently used. 2. Invasive method: that is, gastric mucosal tissue needs to be taken through endoscopy to detect HP.

Rapid urease method. The principle is that HP is rich in urease, decomposes urea to produce ammonia, makes the reaction alkaline, and is colored by the pH indicator, the method is simple, fast and sensitive, but some bacteria will also have urease, so there is a possibility of false positives. Bacterial culture method.

Gastric mucosal biopsies were taken for HP culture, which is accurate and reliable, but the culture is time-consuming. Pathological assays. The best staining method for gastric mucosal tissue sections is the silver staining method, with high detection rate and reliable results.

In general, two or more methods must be positive for the diagnosis of HP. **After long-term follow-up, two consecutive negative urea breath tests, coupled with a progressive decrease in serum anti-HP antibody titers for more than 1 year, were used as the "gold standard" for **HP. Additional Information:

The prevention and control of gastric cancer has attracted increasing attention. Studies have shown that Helicobacter pylori is one of the most common bacterial pathogens in the pyloric part of the human stomach. More than half of the world's population has been infected with H. pylori, and in some countries almost 90% of people have been infected with the bacterium.

People are usually infected at an early age, up to 50% under the age of 5. This bacterial infection first causes chronic gastritis, which leads to stomach ulcers and gastric atrophy, and in severe cases, stomach cancer. According to statistics, the incidence of atrophic gastritis and gastric cancer is high in people who are first infected with Helicobacter pylori at an earlier age, and there is a parallel relationship between the mortality rate of Helicobacter pylori infection and gastric cancer.

Helicobacter pylori parasitizes the tissues of the gastric mucosa, and 67% of 80% of gastric ulcers and 95% of duodenal ulcers are caused by Helicobacter pylori. The common symptoms of patients with chronic gastritis and peptic ulcer are: post-food epigastric fullness, discomfort or pain, often accompanied by other adverse symptoms, such as belching, bloating, acid reflux and loss of appetite.

Some patients may also have recurrent severe abdominal pain and a small amount of upper gastrointestinal bleeding. Based on this, experts believe that early detection of Helicobacter pylori infection and timely and effective use of antibiotics to kill Helicobacter pylori are of great significance for the prevention and control of gastric cancer.
