Infection with Helicobacter pylori may lead to heavy breath, that is, bad smell in the mouth, and in severe cases, there is often a special bad breath that cannot be removed no matter how clean it is.

Commonly used detection methods are: cassette breath test, invasive method (mainly refers to the method that must be examined by gastroscopy biopsy specimen, which is the current routine method of gastroenterology. It includes isolation and culture of bacteria and direct smear, rapid urease test, and antimicrobial susceptibility test. The non-invasive method mainly refers to the method of diagnosing HP specimen infection without taking a biopsy specimen through gastroscopy.

Hello, the Helicobacter helicobacter test needs to be prepared on an empty stomach, and the results of the examination will often be affected after eating, and if you do gastroscopy, there may be complications of aspiration.

This is necessary on an empty stomach, the hospital uses an air bag for examination, and after blowing, you will be asked to take a pill and wait for 15 minutes to blow the air bag for another examination. Helicobacter pylori physical examination.

Although these two tests are not invasive tests, there is no clear rule that the examination should be done on an empty stomach, but in small grams.

It seems that carbon-14

and carbon 13 before the examination is best fasting. Because some patients do not have just this one type of examination, doctors sometimes prescribe other examinations to patients, and the endoscopic examination method is mainly a rapid urease test, which needs to be done on an empty stomach because of gastroscopy.

The examination needs to be fasting, otherwise it will be unclear because the gastric mucosa is covered with food, which will affect the examination, and even cause reflux to tracheal aspiration due to intubation, so it must be fasting.

Detection for Helicobacter pylori infection.

According to the method of collection, it is divided into two categories: invasive and non-invasive. Invasive methods mainly use gastroscopic forceps to remove biopsies for histological testing, bacterial culture, rapid urease test, molecular biology techniques, etc. As required for gastroscopy, fasting is required.

In daily life, not only should you pay attention to the cleanliness of your teeth and mouth, but also pay attention not to share personal belongings with other people, especially toothbrushes and mouthwash cups. In addition, it is best to use the utensils separately, even if you eat at home, it is best to implement a separate meal system, so as to avoid contact with saliva.

In addition, for some patients who are tested positive for Helicobacter pylori infection, in order to better diagnose and understand the gastric lesions, doctors sometimes prescribe gastroscopy and other examinations, and gastroscopy must be strictly fasting. Therefore, when it is best to detect carbon-13 and carbon-14 on an empty stomach, the commonly used detection methods are: cassette breath test, invasive method (mainly refers to the method of biopsy specimen examination that must be taken through gastroscopy, which is the routine method of gastroenterology.

When doing the Helicobacter pylori insufflation test, you need to fast. And if you want to do the examination on the second day, then you can eat and drink normally before 12 o'clock in the evening on the first day, and you can't eat and drink after 12 o'clock. It takes more than eight hours to fasting before the insufflation test can be done.

You should have an empty stomach on the morning of the test, and you should not eat after 10 p.m. before the test. Now the most widely used is insufflation test, which has a high positive rate and is non-invasive. If Helicobacter pylori infection is found.

Please make the relevant **,

The blow test for Helicobacter pylori requires fasting, which can be done in the morning on an empty stomach or more than 2-3 hours after a meal. This test involves swallowing a tablet of a carbon-14-labeled drug, which is broken down into gas in the stomach and then tested.

Helicobacter pylori can break down the drug into a gas, blow it out and collect it for testing. After eating, it is possible that complex things in the food will react with the tablets and also produce gas, which can lead to inaccurate examinations.

Therefore, if you want to test for H. pylori, you should test on an empty stomach or more than 2-3 hours after a meal.

Yes, it is usually recommended to have an empty stomach or two hours after a meal in order to facilitate the examination, and it is always good to follow the doctor's advice.

Yes, this is a must, if you don't have an empty stomach, there will be problems with the examination.

Helicobacter pylori is a major pathogenic bacterium of gastric diseases that can grow in a strong acid environment, which will be transmitted through a variety of ways, once infected, if not timely, it can develop into chronic superficial gastritis, mucosal inflammation and infiltration, and mucosal epithelial hyperplasia, gland atrophy and intestinal metaplasia, and eventually can cause carcinogenesis, so once the examination results show that it has been infected by the pylorus, it is recommended to do it as soon as possible**.

Precautions: 1. On the day of the test, the patient needs to fast or fast for three hours before the examination.

2. The capsule should be taken orally with warm water completely, and should not be bitten, so as not to affect the accuracy of the test results.

3. Taking antibiotics, bismuth, proton pump inhibitors and other Helicobacter pylori sensitive drugs within 3 days before diagnosis may affect the diagnosis results, please stop using such drugs before testing. If you have a history of taking medications, be sure to explain it to your doctor.

4. Acute bleeding in the upper gastrointestinal tract can inhibit Helicobacter pylori, so it should be tested one week after the gastrointestinal bleeding stops.

5. Gastrectomy may cause rapid emptying of isotopes from the stomach, which will affect the detection effect of Helicobacter pylori.

6. Pregnant women and lactating women should avoid this examination.

Helicobacter pylori testing requires fasting, and you can go to a designated hospital or physical examination center for examination.

There are two types of diagnostic methods for Helicobacter pylori:

1) Invasive diagnosis: This kind of diagnosis requires the use of gastric biopsy tissue taken by gastroscopy first, and then HP detection, which brings greater pain to your patient and is a traumatic examination.

2) Non-invasive diagnosis: This type of diagnosis does not require the use of gastroscopy and does not require the acquisition of gastric biopsy tissue, which is a painful and non-invasive examination. Among the non-invasive diagnostic methods, the newly invented 14C-urea breath test (14C-UBT) is the most commonly used.

14C-urea breath test (14C-UBT).

A 14C-urea breath test (14C-UBT) is performed in which the patient blows into a special breath bottle on an empty stomach in the morning or two hours after eating, and the device can be used to detect HP infection. The entire diagnostic process takes no more than 40 minutes. Simple, fast, accurate, painful, non-invasive, no risk of cross-infection, and low cost are the biggest advantages of this diagnosis, and it is also the main reason why it is popular with the majority of patients.

14C-UBT is best suited for the following types of patients or situations.

1. Patients with initial diagnosis of dyspepsia (no long medical history, less than 45 years old and no gastric cancer alarm symptoms), follow-up patients.

2. Patients with gastric and duodenal ulcers, chronic active gastritis, gastritis, gastric mucosa-associated lymphoid tissue malignant lymphoma, etc.

3. Prevention of gastric cancer or family history of gastric cancer;

4. Those who refuse gastroscopy (unless gastric cancer is suspected to be biopsied);

5. Long-term use of non-steroidal anti-inflammatory drugs.

Precautions for 14C-urea breath test.

1. The following factors may affect the diagnostic results of this experiment:

1) Have used antibiotics, bismuth preparations, proton pump inhibitors and other HP-sensitive drugs within one month. Therefore, these drugs should be discontinued within one month before testing.

2) Acute bleeding in the upper gastrointestinal tract can inhibit HP, which may make the test negative. Gastrointestinal bleeding for more than one week does not affect the accurate diagnosis.

3) Partial gastrectomy may result in rapid emptying of isotopes from the stomach or hypochlorhydria in the patient.

4) Pregnant and lactating women should not do this test.

If you want to do a blow test, you can come to Beijing Chaoyang Hospital of Integrated Traditional Chinese and Western Medicine for examination.

Many formal technologies are mature. It depends on what you expectThe attitude is good, if you go to this house.

Helicobacter pylori testing should be done on an empty stomach, so that the examination is more accurate.

Hello, Helicobacter pylori test requires fasting.

There are many methods to detect Helicobacter pylori: direct examination of bacteria, determination of uremia enzyme activity, etc

Polymerase chain reaction, C14 breath tester and breath test bag, to name a few.

Helicobacter pylori is a pathogen that has a great impact on gastrointestinal health, and if not controlled in time, it may also cause cancer, and even stomach cancer. Therefore, when the stomach is upset, it is necessary to check in time, especially to check for Helicobacter pylori, so does the Helicobacter pylori test need to be fasted?

There are several methods for Helicobacter pylori examination, but the commonly used ones are gastroscopy, or carbon 13 breath test, carbon 14 wide no breath test, etc. However, no matter which method is used, the patient is required to have an empty stomach, and only when the examination is performed in an empty state can the accurate test results be obtained. If the examination is carried out after eating, the accuracy of the examination will be affected and the purpose of diagnosing the disease will not be achieved.

These examination methods have different requirements for fasting time, if it is to pass carbon.

Ten. 3. 14 breath test for examination, the fasting requirement time is very short, as long as the fasting is more than six hours. But if the doctor asks the patient to have a gastroscopy, the dust tease will need to be fasted for more than twelve small pies.

The purpose of the inspection is different depending on the method taken. If you are usually in good health and just do a routine physical examination, then it is recommended to take carbon.

Ten. The 3rd and 14th breath tests are fine, and this test is painless. But if there is severe stomach upset, a gastroscopy is required.

The Helicobacter pylori breath test requires fasting and cannot be eaten. There are many ways to test for Helicobacter pylori: direct examination of bacteria, uremia enzyme activity measurement, polymerase chain reaction, C-14 breath detector and breath test bag, etc.

Helicobacter pylori needs to be examined on an empty stomach, and Helicobacter pylori can be checked by gastroscopy, which is urease, and pathological examination is done in the patient's gastric mucosal tissue, and Helicobacter pylori can be checked in the pathological examination, and Helicobacter pylori can also be examined by culture of gastric mucosal tissue.

Of course, there is also a gastroscopy under the gastroscope to take the patient's gastric mucosal tissue to do PCR examination, to see if there is the presence of Helicobacter pylori, the patient can also go to the hospital in the morning to do a C14 breath test to check for Helicobacter pylori, in addition to these examination methods, you can also weigh the blood test method to check for Helicobacter pylori antibodies, these are all ways to check for Helicobacter pylori, no matter what kind of examination method is required to check on an empty stomach.
