Early Detection Of Coeliac Disease

Coeliac disease is a chronic autoimmune disorder triggered by the digestion of gluten (a protein found in wheat, barley, and rye). It affects about 1 in 100 people in the UK, though many cases remain undiagnosed in London and across the country.

If left undiagnosed and untreated, coeliac disease can lead to serious complications, including malnutrition, osteoporosis, and infertility. It also increases the risk of certain types of cancer. Early detection is key, and a coeliac disease blood test is an important first step toward diagnosis.

Why Get Tested?

If you experience persistent gastrointestinal symptoms such as bloating, diarrhoea, or abdominal pain, or if you suffer from fatigue, anaemia, or unexplained weight loss, this test may help identify Coeliac disease.

It is also recommended if you have a family history of the condition, as it can be hereditary.

Who Should Get Tested?

Did you know that over 300 000 tests for Coeliac disease antibodies (e.g., tTG-IgA) are performed annually? While anyone can develop Coeliac disease, certain people are at a higher risk and should consider testing. You may be at an increased risk if:

You have a first-degree relative (parent, sibling, or child) with Coeliac disease.
You have been diagnosed with an autoimmune disorder, such as Type 1 Diabetes or thyroid disease.
You suffer from other conditions like Down syndrome or Turner syndrome.
You exhibit persistent symptoms associated with malabsorption, like diarrhoea, fatigue, or nutrient deficiencies

Test Result Possibilities

The results of your Coeliac disease blood test will indicate whether your levels of these various antibodies are raised, which can help indicate the reaction of your immune system to gluten.

Positive: If your antibody levels are above a certain threshold, it could indicate that you have Coeliac disease. In such a case, your doctor will most likely recommend further testing, such as an intestinal biopsy, to confirm the diagnosis.
Negative: If your antibody levels turn up within the normal range and you remain symptomatic, your doctor will look for other causes or may suggest additional tests that will check for sensitivity to gluten or IgA deficiency.

Why Getting Diagnosed Early Is Important

Left untreated, Coeliac disease can lead to significant health complications, including:

Osteoporosis: Due to impaired calcium and vitamin D absorption.
Infertility And Miscarriage: Resulting from chronic malnutrition.

Neurological Issues: Such as peripheral neuropathy or seizures.
Increased Cancer Risk: A small but increased risk of small bowel lymphoma and other cancers.

Procedure

Type of sample taken: Blood

Preparing for test

Our clinics in London generally do not require you to fast for your coeliac disease blood test. You can eat normally unless otherwise advised by your healthcare provider. The test checks for antibodies that react to gluten, so avoiding gluten may result in false-negative results. Common gluten-containing foods include bread, pasta, and cereals. Please prepare a list of any symptoms you are experiencing (e.g., bloating, diarrhoea, fatigue) as well as any family history of coeliac disease. This information helps your healthcare provider better assess your results.

During the test

A healthcare professional will collect a small blood sample from a vein in your arm using a needle. The blood draw typically takes around 5 – 10 minutes. The entire appointment may last around 30 minutes, including paperwork and waiting time. If you are anxious about needles, inform us, so we can help make the experience as comfortable as possible. Feel free to ask your healthcare professional any questions about the procedure or discuss any symptoms you’re experiencing with your doctor.

Results

Apply pressure to the puncture site to minimise bruising and keep the area clean. A small bandage will usually be applied. You may experience minor discomfort or bruising, but this should subside within a few days. The test results may take a few days to a week, depending on the lab. Your doctor will explain what the antibody levels indicate in relation to Coeliac disease. If the test shows elevated antibodies, further testing, such as a small intestine biopsy, may be recommended to confirm the diagnosis.

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.

Why is a Coeliac disease blood test necessary?

This test is essential for diagnosing Coeliac disease, an autoimmune condition where the body reacts to gluten, causing damage to the small intestine.

Can I take the test if I am already on a gluten-free diet?

It is best to take the test while you are still consuming gluten, as removing gluten from your diet can cause antibody levels to drop, leading to false-negative results.

How accurate is the Coeliac disease blood test?

The blood test is highly accurate, with a sensitivity of around 95% for detecting coeliac disease when testing for the tTG-IgA antibody.

Can coeliac disease blood tests differentiate between coeliac disease and gluten sensitivity?

No, blood tests specifically detect antibodies linked to coeliac disease and intestinal damage. Non-coeliac gluten sensitivity (NCGS) does not produce these antibodies and does not cause the same immune response or intestinal damage, so blood tests for coeliac disease will typically be negative in NCGS.
