Helicobacter pylori is a gram-negative microaerophilic curved bacillus with an affinity for human gastric mucosa. H. pylori has been identified as an important pathogen in the upper GI tract. The casual relationship between H. pylori and chronic active gastritis, duodenal ulcers, and gastric ulcers has been well documented. BreathTek™ UBiT® for H. pylori is a non-invasive, non-radioactive method for detecting urease activity associated with H. pylori infection. It is FDA approved to confirm cure and offers 95.2% sensitivity and 89.7% specificity compared with endoscopic methods.

Description: The H Pylori antigen test is used to detect the bacteria, helicobacter pylori, that is a major cause of peptic ulcer disease.

Also Known As: H. Pylori Antigen Test, Stool Antigen Test

Collection Method: Patient Self Collection Kit provided by Patient Service Center

Specimen Type: Stool (Feces)

Test Preparation: Patient Self Collection Required – Instructions Below

  1. Patient to visit a Quest Patient Service Center to obtain the designated sterile collection container required for the test.
  2. Patient self-collects stool sample off site from PSC.
  3. Patient self-collects 0.5 mL or 0.5 grams of semi-solid stool or 20 mm diameter solid stool and transfer to properly labeled plastic, leak-proof container.
  4. Label the specimen collection container: a. Record the date and time on the specimen collection. b. Record the patient’s full name as on requisition and DOB.
  5. IMPORTANT: Watery, diarrheal stool is not acceptable.
  6. IMPORTANT: The stool sample must be refrigerated immediately after collection.
  7. The stool specimen must be packed with cold packs and returned to the Quest Patient Service Center with the Patient Requisition within 24 hours of collection.

Patient Preparation

For initial diagnostic purposes no special patient preparation is required. Patients are not required to be off of medications or to fast before this test. While positive test results from patients taking agents such as proton pump inhibitors and antimicrobials should be considered accurate, false negative results may be obtained. For this reason, physicians may suggest the patient go off medications for two weeks and repeat test if negative results are obtained.

To confirm eradication, testing should be done at least 4 weeks following the completion of treatment. However, a positive test result 7 days’ post therapy is indicative of treatment failure.

When is a Helicobacter Pylori test ordered:

When someone complains of stomach pain and exhibits ulcer-related symptoms, testing may be required.

When an individual has finished taking the recommended course of antibiotics, H. pylori tests may also be requested to ensure that the H. pylori bacteria have been eradicated. However, not every patient has a follow-up examination.

What does a Helicobacter Pylori stool test check for?

An organism known as Helicobacter pylori is a major contributor to the development of peptic ulcer disease. Testing for H. pylori identifies a gastrointestinal infection brought on by the bacteria.

H. pylori is quite widespread, particularly in underdeveloped nations. As much as 50% of people on the planet have the bacteria in their stomachs and intestines. The majority of persons affected by H. pylori will never have any symptoms, although it does raise the risk of stomach cancer, chronic gastritis, and ulcers. Due to the bacteria, the stomach is less able to generate mucus, which increases the risk of acid damage and peptic ulcers.

It is not advised to perform an antibody test on blood samples for routine diagnosis or to assess the efficacy of treatment. This test does not differentiate between a current illness and a former infection; it only finds antibodies to the bacterium. It is improbable that a person has ever had an infection with H. pylori if the antibody test is negative. A stool antigen or breath test should be used to validate results if they are ordered and positive.

Lab tests often ordered with a Helicobacter Pylori test:

  • Gastrin

Conditions where a Helicobacter Pylori test is recommended:

  • Peptic Ulcer

How does my health care provider use a Helicobacter Pylori test?

Testing for Helicobacter pylori is used to identify bacterial infections and assess how well a treatment is working. A H. pylori infection is linked to a higher risk of stomach cancer, chronic gastritis, and ulcers.

For the diagnosis of an H. pylori infection and the assessment of the efficacy of treatment, the stool antigen test and urea breath test are advised. Because they are quick and noninvasive, these tests are the ones that are used the most. Invasive endoscopy-related tests can also be used to identify and assess H. pylori, but they are less typically used as a result.

What do my H Pylori test results mean?

When a person's stool antigen or breath test for H. pylori is positive, it is likely that the bacteria are to blame for their peptic ulcer. To eradicate the germs and halt the pain and ulceration, a course of treatment combining antibiotics and other drugs will be advised.

If a test is negative, it is quite improbable that the subject has an H. pylori infection, and it is possible that the subject's signs and symptoms are caused by something else. To more definitively rule out infection, additional testing, such as a more invasive tissue biopsy, may be performed if symptoms continue.

Description: Fecal Globulin by immunochemistry is a test that measures the amount of blood present in fecal samples. The results from the fecal globulin test can be used to detect a lower gastrointestinal disorder. It is recommended to be a part of the routine physical examination.

Also Known As: Fecal Immunochemical Test, Fecal Occult Blood Test, Stool Occult Blood Test, FIT, FOBT

Collection Method: Fecal specimen collected from toilet water and brushed onto InSure® FOBT test card

Specimen Type: Fecal Specimen

Test Preparation: No preparation required

When is a Fecal Globin test ordered?

When a person chooses fecal occult blood testing as a method of colon cancer screening, the American Cancer Society and other major healthcare organizations recommend yearly testing. The American Cancer Society and others recommend that colon cancer screening begin around age 50 for the general population, but it may begin earlier if a person has a family history of colon cancer.

An FOBT may be ordered by a doctor if a patient has unexplained anemia that could be caused by gastrointestinal bleeding.

What does a Fecal Globin test check for?

The majority of colon cancer cases begin with the formation of benign intestinal polyps. Benign polyps are quite common in adults over 50, and while the majority do not cause health problems, some can turn malignant and spread to other parts of the body. These finger-like growths protrude into the rectum or the intestinal cavity. They can be delicate and bleed on occasion, as when food debris rubs against them.

The blood expelled is normally not visible in the stool, but a fecal occult blood test or a fecal immunochemical test can detect it. The FOBT and FIT are effective colorectal cancer screening techniques because this small amount of blood may be the earliest and sometimes only evidence of early colon cancer. A guaiac-based test, an over-the-counter flushable reagent pad, and an immunochemical technique are all options for testing.

It is advised that at least three stool samples be taken on different days be tested. According to the American Cancer Society, a single test performed during a digital rectal exam at a doctor's office is not recommended since it may not be sensitive enough to detect cancer. Because collecting feces on three different days increases the chances of identifying cancer, the home FOBT or FIT is advised. Additionally, those who choose this type of colon cancer screening should be screened every year.

Lab tests often ordered with a Fecal Globin test:

  • Complete Blood Count (CBC)
  • Calprotectin

Conditions where a Fecal Globin test is recommended:

  • Colon Cancer

How does my health care provider use a Fecal Globin test?

The fecal occult blood test, also known as the fecal immunochemical test, is primarily used to screen for early colon cancer. The majority of colon cancer cases begin with the formation of benign intestinal polyps. People over the age of 50 are more likely to develop benign polyps. The majority are non-cancerous, however some can develop malignant.

Blood in the stool could be the only sign of early cancer, so if caught early, therapy can begin right away, increasing the chances of a cure.

What do my Fecal Occult Blood test results mean?

Normally, the fecal occult blood test is negative.

A positive test result for the guaiac-based FOBT shows that abnormal bleeding is occurring anywhere in the digestive tract. Ulcers, diverticulosis, polyps, inflammatory bowel disease, hemorrhoids, blood eaten owing to bleeding gums or nosebleeds, or benign or malignant tumors could all cause blood loss.

A positive result for the fecal immunochemical test shows abnormal bleeding in the lower digestive tract. Other sources of blood, such as those found in the diet, do not generate a positive result since this test only identifies human hemoglobin. Furthermore, hemoglobin from upper digestive tract hemorrhage is broken down before reaching the lower digestive tract and is undetectable by the FIT. As a result, the FIT is a more precise test than the gFOBT.

Follow-up testing is required after a positive result from either the guaiac-based FOBT or the immunochemical FIT. Direct imaging of the colon and rectum is generally used.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Most Popular

Description: The gastrin test is used to measure gastrin, a hormone that controls stomach acid. The test measures gastrin levels in your blood’s serum.

Also Known As: Gastrinomas Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Overnight fasting (12 hours) required

When is a Gastrin test ordered?

When a patient experiences diarrhea, abdominal pain, and/or recurring peptic ulcers that do not improve after treatment and that the doctor feels are brought on by excessive gastrin production, a gastrin test may be recommended. When a patient's gastrin level is moderately increased and a doctor feels they may have a gastrinoma, they may be given a gastrin stimulation test.

A periodic gastrin test may be requested as a screening test to check for recurrence after a gastrin-producing tumor has been excised.

What does a Gastrin test check for?

The "G-cells" in the antrum, a region of the stomach, create the hormone called "gastrin." During the digestion process, it controls the amount of acid produced in the stomach. To assess a person with recurrent peptic ulcers and/or other severe gastrointestinal symptoms, this test analyzes the level of gastrin in the blood.

The antrum of the stomach swells as food is consumed, and the meal itself causes gastrin to be released. The production of stomach acid is then stimulated by the hormone gastrin. Acidity aids in food digestion, and when it increases, it eventually inhibits the release of gastrin. Low levels of gastrin are often produced by this feedback system, especially while a person is fasting. An excess of gastrin and stomach acid can be brought on by uncommon disorders such G-cell hyperplasia and gastrinomas, including Zollinger-Ellison syndrome. Aggressive peptic ulcers that are challenging to treat may result from this.

Gastrinomas are tumors that make gastrin. One or more gastrinomas can result in ZE syndrome, which is characterized by excessive gastrin levels, significantly increased stomach acid production, and peptic ulcers. Despite the fact that the pancreas' endocrine cells don't typically produce gastrin, gastrinomas frequently develop there. More than half of them are cancerous, leading to cancer that can spread to different organs including the liver. Large amounts of gastrin can be produced by even the smallest tumors.

Lab tests often ordered with a Gastrin test:

  • Helicobacter Pylori (H. Pylori)
  • Gastric Acid

Conditions where a Gastrin test is recommended:

  • Endocrine Syndromes
  • Gastrinomas

How does my health care provider use a Gastrin test?

The main purpose of the gastrin test is to identify cases of excessive gastrin and stomach acid production. It is used to assist in the diagnosis of Zollinger-Ellison syndrome, hyperplasia of G-cells, and gastrinomas, which are gastrin-producing tumors. The stomach's G-cells are specialized cells that create gastrin, which boosts the production of gastric acid.

After a gastrinoma has been surgically removed, a gastrin test may be used to check for recurrence.

Therefore, if the initial gastrin test result is moderately but not significantly high and the healthcare professional feels that a person's symptoms are brought on by a gastrinoma, a gastrin stimulation test may be conducted to provide additional information. This process entails taking a baseline sample of gastrin, administering a drug to the patient to increase gastrin synthesis, and then taking more blood samples at certain intervals for gastrin testing. After secretin administration, the other sources of high gastrin won't exhibit a rise.

To aid in the diagnosis of ZE syndrome, a measurement of the pH level of gastric acid may occasionally be requested before, during, or after a gastrin test.

What do my Gastrin test results mean?

It is uncommon to be concerned about low or normal blood levels of gastrin.

A number of diseases and illnesses, including ZE syndrome, pernicious anemia, G-cell hyperplasia, chronic atrophic gastritis, chronic kidney failure, and pyloric blockage, can cause somewhat elevated levels.

A person is likely to have ZE syndrome and one or more gastrinomas if their gastrin levels are significantly elevated in symptomatic persons and increase significantly after a gastrin stimulation test. In order to find the gastrinomas, imaging tests may be prescribed as a follow-up to elevated gastrin concentrations. Both the size and the number of tumors have no effect on how much gastrin is produced. Large volumes of gastrin can be produced by even small tumors.

Following surgical resection of a gastrinoma, low-grade gastrin levels that later rise could indicate a return of the tumor. Concentrations that remain elevated following treatment may be a sign that it wasn't entirely successful.

Helicobacter pylori, or H. pylori, is an extremely common bacteria that infects the majority of the world's population. By many estimates, approximately 60 percent of adults worldwide carry H. pylori in their stomachs. Some people never experience any symptoms from the infection, but others can develop stomach ulcers, inflammation, and even stomach cancer.

It might be a bit unsettling or even frightening to realize that you might have been carrying a potentially harmful bacteria for much of your life. This could be even more true if you have recently developed peptic ulcer disease or are experiencing other uncomfortable digestive symptoms.

The good news, however, is that there are simple, effective H. pylori tests that can help you make informed decisions about your health. Once you have been screened for H. pylori, you and your doctor can diagnose, monitor, and treat your condition. 

Read on for more information about H. pylori infection, signs and symptoms, and how to screen for, diagnose, and monitor the condition.

About H. Pylori

H. pylori is a common bacteria that lives in the digestive tract. It can infect your stomach lining for years or decades before you develop complications, which can make it very difficult to know whether you've been infected with H. pylori without proper testing. In fact, some people never experience any symptoms from their infection.

Other people, however, can develop gastritis (inflammation of the stomach lining), peptic ulcer disease, or even gastric cancer. This happens when the bacteria damage the lining of the stomach enough that stomach acid begins to cause ulcers, bleeding, and other problems.

Risk Factors for H. Pylori

There are many risk factors for H. pylori infection. Many people pick up the bacteria as children but don't show symptoms for years. Living conditions in childhood can increase your risk for contracting H. pylori.

Living in crowded conditions, lacking reliable access to clean water, living in a developing country, and/or sharing housing with someone who is infected can greatly increase your risk of contracting H. pylori as a child.

Causes of H. Pylori

You can get H. pylori in many ways, including through food, water, and eating utensils. You can also get H. pylori directly from someone who is infected via saliva, vomit, or other bodily fluids.

Doctors don't fully understand why some people who are infected with H. pylori never develop any complications, and why others contract ulcers or even stomach cancer. This means that a laboratory test can be especially helpful as you monitor your own symptoms.

Signs and Symptoms of H. Pylori

Ulcers can cause extreme discomfort and pain and can damage the lining of your stomach. Some common symptoms of ulcers are:

  • Gnawing or burning pain in your abdomen, especially between meals
  • Pain that improves temporarily when you eat, drink milk, or take an antacid
  • Nausea or vomiting
  • Bloating
  • Gas or frequent burping
  • Unexpected weight loss
  • Loss of appetite
  • Heartburn

When to See Your Doctor Immediately

Sometimes, ulcers can cause internal bleeding, which can be very dangerous. See your doctor right away if you experience:

  • Bloody, dark red, or black stool
  • Bloody or black vomit, or vomit that looks like coffee grounds
  • Severe, repeated stomach pain
  • Trouble breathing or difficulty swallowing

The symptoms of stomach cancer are difficult to identify at first, and you may experience heartburn or another discomfort that could be mistaken for side effects of ulcers. You may also experience:

  • Swelling and pain in the belly
  • Consistent nausea and loss of appetite
  • Trouble eating more than small amounts
  • Unexpected weight loss
  • Vomiting

Since these symptoms can easily be mistaken for other gastrointestinal issues, it is very important to test and monitor for Helicobacter pylori infection and discuss your treatment with your doctor.

Lab Tests for H. Pylori

Fortunately, there are several effective H. pylori tests that can help you take charge of your health. The most common tests are stool tests and breath tests. Sometimes a doctor may order a scope test, but this is typically for more advanced symptoms or as a follow-up to determine the best treatment options.

Stool Tests

stool antigen test looks for foreign proteins associated with H. pylori in your stool. Accurate, straightforward stool tests can be ordered directly from the lab; there are just a few things you should know ahead of time.

Many common medications can occasionally interfere with the accuracy of these tests. You are not necessarily required to stop taking medication for your tests from Ulta Lab Tests. However, in the event of a negative result, your doctor may recommend that you stop taking antibiotics and proton pump inhibitors (PPIs) for two weeks before a follow-up test.

Breath Tests

The urea breath test is a simple, non-invasive, non-radioactive test with highly accurate results. You simply swallow a pill, liquid, or pudding that contains urea. You'll then breathe into a bag. H. pylori will change the substance into carbon dioxide, so if you have it, the test results will show higher levels of carbon dioxide than normal.

For the greatest accuracy, you should stop taking antibiotics, PPIs, and bismuth preparations (such as Pepto-Bismol) two weeks before the test.


Looking for even more information? Here are some of the most frequently asked questions about these tests.

Which Test Is Better for Me?

All tests at Ulta Lab Tests are highly accurate, with patient-friendly processes. The stool test requires self-collection at home before dropping it off at a collection center. The urea breath test is done quickly at a patient service center but has more stringent requirements on medication use ahead of time. 

How Quickly Will I Get My Results?

It can vary. However, your results are typically available online after just 1-2 business days.

Is My Information Secure?

Absolutely. Your results are private and secure, and your information is carefully safeguarded. No one else will see your results unless we are required to release them by law.

What if I Don't Have Insurance?

Insurance is not required for our tests. Our pricing is affordable to everyone.

What Are My Treatment Options for H. Pylori?

H. pylori is typically treated with a combination of two different antibiotics, which prevents the bacteria from becoming fully resistant to one of them. You may also return to taking PPIs and bismuth preparations. Your doctor will typically order a second test after four weeks to see if treatment was effective.

Schedule H. Pylori Tests

There are many benefits to taking advantage of available H. pylori tests through Ulta Lab Tests. Knowing your results can allow you to take control of your health, and to go into a doctor's appointment fully prepared and informed.

If you are suffering from ulcers or gastrointestinal distress, finding out whether you have H. pylori can help you treat the infection. This can prevent further damage to the stomach lining, which in addition to pain and discomfort could eventually lead to internal bleeding or even stomach cancer.
