H Pylori Rapid Test

H.pylori Rapid Test include H.pylori Antigen Rapid Test and H.pylori Antibody Rapid Test.

 

H.pylori Antigen Rapid Test (Feces) is a rapid chromatographic immunoassay for the qualitative detection of H. pylori antigens in human feces specimens to aid in the diagnosis of H. pylori infection. And the H.pylori Antibody Rapid Test (Serum/Plasma/Whole Blood) is for the qualitative detection of antibodies to H. pylori in whole blood, serum, or plasma.

H. pylori is a small, spiral-shaped bacterium that lives in the surface of the stomach and duodenum.

It is implicated in the etiology of a variety of gastrointestinal diseases, including duodenal and gastric ulcer, non-ulcer dyspepsia and active and chronic gastritis. Both invasive and non invasive methods are used to diagnose H. pylori infection in patients with symptoms of gastrointestinal disease. Specimen-dependent and costly invasive diagnostic methods include gastric or duodenal biopsy followed by urease testing (presumptive), culture, and/or histologic staining. Non-invasive techniques include the urea breath test, which requires expensive laboratory equipment and moderate radiation exposure, and serological methods.Individuals infected with H. pylori develop antibodies which correlate strongly with histologically confirmed H. pylori infection.

A very common approach to the diagnosis of H. pylori infection is the serological identification of specific antibodies in infected patients. The main limitation of serology test is the inability to distinguish current and past infections. Antibody may be present in the patient's serum long after eradication of the organisms.HpSA (H. pylori Stool Antigen) testing is gaining popularity for diagnosis of H. pylori infection and also for monitoring the efficacy of the treatment to H. pylori infection.

 

The H. pylori Antibody Rapid Test (Serum/Plasma/Whole Blood) is a simple test that utilizes a combination of H. pylori antigen coated particles and anti-human IgG to qualitatively and selectively detect H. pylori antibodies in whole blood, serum, or plasma. And the H. pylori Antigen Rapid Test (Feces) utilizes antibodies specific for H. pylori antigens to selectively detect H. pylori antigens in human feces specimens.

1. What Is an H. pylori (Helicobacter pylori) Test?

H. pylori tests show if you have an H. pylori infection. H. pylori (Helicobacter pylori) is a type of bacteria that infects your stomach and small intestine. These bacteria damage the lining of your stomach over time, which can lead to irritation, gastritis or peptic ulcers.

If you have symptoms of these conditions, your provider might suggest an H. pylori test. You might also need one after treatment to make sure the infection is gone. There are several types of Helicobacter pylori tests. Your provider will recommend the best one for you.

2. When would I need an H. pylori test?

Your healthcare provider may order an H. pylori test if you have symptoms of a stomach ulcer or signs of gastritis. These may include:

● Gnawing or burning pain in your middle or upper belly, especially between meals or at night

● Belly pain that improves if you eat something or take an antacid

● Bloating

● Nausea or vomiting

3. What are the tests for H. pylori?

There are four main ways your provider can test for an H. pylori infection:

● Breath test

● Stool (poop) test

● Blood test

● Endoscopy and biopsy

Here's what each test involves:

● H. pylori breath test (urea breath test)

The H. pylori breath test is the most common test for H. pylori infection. It measures the amount of carbon dioxide in your breath after you drink a special solution containing urea. H. pylori bacteria break down urea into carbon dioxide. Excess carbon dioxide in your breath is a sign of an H. pylori infection.

● H. pylori stool test

An H. pylori stool antigen test (SAT) detects antigens associated with H. pylori in your poop. Antigens are markers that allow your immune system (your body's infection-fighting system) to identify germs. Having H. pylori antigens in your poop means that you have the bacteria in your digestive tract.

● H. pylori blood test

An H. pylori blood test looks for antibodies linked to an H. pylori infection. Antibodies are proteins your immune system makes to fight germs. They travel through your blood looking for specific bacteria. These antibodies can still be in your blood even after the infection is gone.

For this reason, providers mostly use blood tests to screen for H. pylori infections in populations where the bacteria are more common. H. pylori is more widespread in Africa, South America and western Asia.

● Upper endoscopy (EGD)

An upper endoscopy is the most accurate test for H. pylori. But unlike the others, it's a bit more invasive. Provider uses a thin tube with a camera to look inside your body and take small tissue samples (biopsies) to test in a lab. They may choose this test if they need to check for other issues besides H. pylori.

H. pylori Antibody Rapid Test

H. pylori Antigen Rapid Test

POSITIVE:* Two distinct colored lines appear. One colored line should be in the control line region (C) and another colored line should be in the test line region (T).

*NOTE: The intensity of the color in the test line region (T) will vary depending on the concentration of H. pylori antigens present in the specimen. Therefore, any shade of color in the test line region (T) should be considered positive.

NEGATIVE: One colored line appears in the control line region (C). No line appears in the test line region (T).

INVALID: Control line (C) fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test Cassette. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
