H. Pylori IgG Testing in Puerto Rico

H. pylori IgG testing is a blood test that checks for antibodies your immune system makes against Helicobacter pylori, a common bacterium that can live in the stomach. It is often ordered when someone has ongoing indigestion, stomach pain, or a history of ulcers, to see whether H. pylori may be involved.

What it measures

H. pylori IgG antibodies — Proteins made by your immune system in response to H. pylori; their presence suggests past or current exposure.
Qualitative result — Usually reported as positive, negative, or equivocal (uncertain), rather than a precise number.
Antibody level (if quantitative) — Some labs report a number, but the cut-off for positive varies by lab and is not a direct measure of active infection.

Who it is for

A clinician may order this test if you have persistent stomach symptoms, a known ulcer, or risk factors for H. pylori. It is also sometimes used in people with a family history of stomach cancer.

Preparation

No fasting or special preparation is needed for this blood test. You can eat and drink normally before your appointment.

Results and what they mean

Results are typically available in 1–3 business days and are reported as positive, negative, or equivocal. A positive result means antibodies were found, but it cannot tell whether the infection is current or past. Only a clinician can interpret your result in the context of your symptoms and other tests. This is general information, not medical advice.

Frequently asked questions

Does a positive result mean I have an active infection?

Not necessarily. IgG antibodies can stay in your blood for months or years after the bacteria are gone, so a positive result may reflect a past infection. Your clinician may order a stool or breath test to check for active infection.

Can I eat before this test?

Yes. No fasting is required for H. pylori IgG blood testing.

How is this test different from a breath or stool test?

Breath and stool tests look for active H. pylori, while the IgG blood test looks for your immune response. Blood tests are often used first because they are simple, but they cannot distinguish current from past infection.

Will my insurance cover this test?

Coverage depends on your plan and why the test is ordered. Check with your insurance provider or the lab before testing.
