Peering into Gastric Health: Anti-Helicobacter pylori Testing for Digestive Wellness
Sample Type
stool
Fasting Required
No
Description
Repeat testing after treatment is important to be sure H. pylori is gone. Tests may be done using a stool sample, through a breath test and by an upper endoscopy exam. Stool antigen test. This is the most common stool test to detect H. pylori. The test looks for proteins (antigens) associated with H. pylori infection in the stool. Stool PCR test.

How our test process works!
Repeat testing after treatment is important to be sure H. pylori is gone. Tests may be done using a stool sample, through a breath test and by an upper endoscopy exam. Stool antigen test. This is the most common stool test to detect H. pylori. The test looks for proteins (antigens) associated with H. pylori infection in the stool. Stool PCR test.
These tests diagnose H. pylori, a type of bacteria that mainly infects the stomach.
≤1.7 for a negative result, 1.8 to 2.2 for an equivocal result, and ≥2.3 for a positive
The H. pylori IgG quantitative (Qt) test measures the level of IgG antibodies against Helicobacter pylori bacteria in the blood. Here's how to interpret the test results:
Normal Range:
The normal range for H. pylori IgG antibody levels may vary slightly between laboratories. It is typically expressed in international units per milliliter (IU/mL) or arbitrary units.
Positive Result:
A positive H. pylori IgG quantitative test result indicates the presence of detectable levels of IgG antibodies against H. pylori.
Interpretation:
A positive result suggests current or past exposure to H. pylori bacteria.
However, the presence of IgG antibodies does not necessarily indicate active infection, as antibodies may persist in the blood for an extended period after the infection has been cleared.
Further diagnostic testing may be required to confirm active infection, such as urea breath test (UBT), stool antigen test, or upper endoscopy with biopsy for histological examination.
Negative Result:
A negative H. pylori IgG quantitative test result indicates that IgG antibodies against H. pylori were not detected or were below the assay's detection limit.
Interpretation:
A negative result suggests no detectable levels of IgG antibodies against H. pylori.
It may indicate the absence of current or past exposure to H. pylori, but it does not completely rule out the possibility of infection, especially if the test is performed during the early stages of infection or in individuals with weakened immune systems.
Quantitative Results:
Quantitative results provide the level of IgG antibodies against H. pylori, typically expressed in IU/mL or arbitrary units.
Higher antibody levels may indicate recent or ongoing infection, while lower levels may suggest past exposure or a lower degree of immune response.
Clinical Correlation:
Interpretation of H. pylori IgG quantitative test results should be done in conjunction with clinical findings, medical history, and other diagnostic tests.
Additional testing may be necessary to confirm the presence of active infection and assess the need for treatment.

Frequently Asked Question
Several factors can affect the accuracy of H. pylori IgG Antibody Quantification, including recent antibiotic or proton pump inhibitor (PPI) use, immune status of the individual, and timing of sample collection relative to infection onset.
Elevated levels of H. pylori IgG antibodies indicate exposure to H. pylori bacteria. However, a positive result does not necessarily indicate an active infection, as antibodies may persist in the blood even after successful treatment or in cases of past infection.
H. pylori IgG Antibody Quantification is one of several methods available for diagnosing H. pylori infection. While it offers advantages such as ease of specimen collection and non-invasiveness, it may not be as accurate as other tests, particularly in regions with high prevalence rates.
H. pylori IgG Antibody Quantification cannot reliably differentiate between past and current infections. Additional tests, such as urea breath test, stool antigen test, or endoscopic biopsy, may be needed to confirm the current presence of H. pylori bacteria.
If H. pylori IgG Antibody Quantification results are positive, further evaluation and possibly additional testing may be required to confirm the diagnosis and determine the appropriate treatment plan. This may involve consultation with a gastroenterologist or infectious disease specialist.
This test is performed to diagnose H. pylori infection, assess the immune response to the bacterium, and monitor the effectiveness of treatment in eradicating the infection.
H. pylori IgG Antibody Quantification is not routinely used to monitor treatment response due to the persistence of antibodies in the blood even after successful eradication of the bacteria. Instead, other tests such as urea breath test or stool antigen test are preferred for this purpose.
H. pylori IgG Antibody Quantification is performed using a blood sample collected from the patient. The sample is then analyzed in a laboratory using techniques such as enzyme-linked immunosorbent assay (ELISA) to measure the levels of IgG antibodies specific to H. pylori.
H. pylori IgG Antibody Quantification is typically covered by health insurance when deemed medically necessary for the diagnosis or monitoring of gastrointestinal conditions associated with H. pylori infection. Coverage policies may vary, so it's advisable to check with the healthcare provider and insurance company regarding coverage and any out-of-pocket costs.
