Testing For Helicobacter Pylori

An H pylori test screens for specific antibodies in your blood that are produced by your immune system in response to an Helicobacter pylori infection. If antibodies are found, it usually means you have had or have an H pylori infection.

Doctor considering blood test options

How H Pylori Affects Your Health

Helicobacter pylori is a spiral-shaped bacteria that lives in the stomach lining and is one of the most common causes of gastrointestinal discomfort.

It can cause irritation and inflammation, which might lead to ulcers and, over time, more serious digestive issues if left untreated. And about 40% of people in the UK carry Helicobacter pylori in their stomachs.

H Pylori Symptoms

Ongoing stomach pain, bloating, nausea, or unexplained weight loss are some of the common symptoms associated with H pylori. Other symptoms include feeling full, acid reflux, and discomfort after eating.

This is because this bacteria is known to cause issues like stomach pain, ulcers, gastritis, indigestion, and even stomach cancer. That is why catching it early can help you manage and treat the condition more effectively.

A Closer Look At Possible Results

A negative H pylori test result means that you probably do not have an H pylori infection. However, it could also be that your body has not produced enough antibodies against the infection yet (in the case that it is an active infection). Therefore, if you are dealing with H pylori symptoms, another test (or further testing) may be scheduled.

A positive test result means that you have had or have an H pylori infection. Your doctor will prescribe a suitable treatment and may order additional tests if need be.

What Happens If You Have An H Pylori Infection

If your H pylori blood test comes back positive, you can expect:

  • A course of antibiotics or a combination of antibiotics and other medications to be prescribed. Remember, completing the full course of treatment is essential to fully eliminate the infection and restore your digestive health
  • Additional or follow-up tests to make sure all damage caused has been healed. Once treated, many people experience relief from stomach pain, bloating, and indigestion

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.

fAQ

Is the test accurate?
An H pylori blood test is great for showing if you have been exposed to the H pylori bacteria before. However, it might not always tell if the infection is active right now. Sometimes, additional testing may be required, depending on your family and medical history.
Can an H pylori infection cause serious health problems if left untreated?
Yes, unfortunately it can. It can cause chronic gastritis, stomach ulcers, and even increase your risk of developing stomach cancer. The bacteria can also weaken the protective lining of your stomach and duodenum. This can lead to ulcers and bleeding.
What treatments are available if I test positive?
Treatments usually involve a combination of antibiotics to kill the bacteria and proton pump inhibitors (PPIs) or H2 blockers to reduce stomach acid and promote healing. However, if you test positive, your doctor will advise you on the course of action going forward.
Can H. pylori infection come back after treatment?
Yes, reinfection is possible but uncommon in adults. Most treatments successfully eradicate the bacteria, but incomplete treatment or antibiotic resistance can cause persistence. Your doctor may recommend a follow-up test after treatment to confirm that the infection has been cleared.
