Food Allergy Screening

Food Allergy Screening

Our Food Allergy Screening Panel provides a comprehensive assessment of your immune response to a wide range of common food allergens. By measuring Total IgE and specific IgE antibodies to over 30 foods, including dairy, eggs, fish, nuts, grains, fruits, and vegetables, this test can help identify potential allergic sensitivities that may be contributing to symptoms such as skin reactions, digestive discomfort, respiratory symptoms, or unexplained health concerns. This detailed screening can provide valuable insights to support dietary discussions, allergy management, and personalised healthcare decisions.

Why Food Allergy Screening Matters

Food allergies and sensitivities can cause a wide range of symptoms that are often mistaken for other conditions. Identifying which specific foods trigger a reaction can help you make informed dietary choices and manage symptoms more effectively.

You may benefit from this test if you:

  • Notice symptoms after eating certain foods but aren’t sure which ones
  • Have ongoing digestive discomfort, skin reactions, or respiratory symptoms
  • Want to rule out food allergies as a cause of unexplained symptoms
  • Are considering significant dietary changes and want a clearer picture first

Understanding Your Results

Your kidney function test measures five key markers. Here’s what each one tells you about your kidney health:

Total IgE

Your overall allergic antibody level. Raised Total IgE can suggest a general tendency toward allergic responses.

Specific Food IgE

Individual food results. Raised levels against a specific food suggest your immune system may be reacting to it.

Skin & Digestive Reactions

Common signs linked to food sensitivities, including rashes, hives, bloating, or discomfort after eating.

Respiratory Symptoms

Some food allergies can contribute to symptoms such as sneezing or congestion, alongside other allergen triggers.

Together, these five markers give a clear picture of whether your kidneys are filtering properly, maintaining balance, and working at the level your body needs.

What does Food Allergy Screening check for?

Food Allergy Screening looks at your immune response across two levels:

  • Total IgE – Your overall allergic antibody activity, giving a general picture of allergic tendency
  • Specific IgE antibodies – Your immune response to over 30 individual foods, including dairy, eggs, fish, nuts, grains, fruits, and vegetables

What can affect your results?

  • Recent illness — can temporarily affect IgE levels
  • Existing allergic conditions — such as asthma, hay fever, or eczema can raise Total IgE

  • Age — IgE levels can vary naturally with age

  • Family history — allergic conditions can run in families
  • Medications — certain medications may affect antibody levels
  • Skin conditions — conditions like eczema are often linked to raised IgE
  • Existing sensitivities — previously identified allergies may affect the overall pattern of results
  • Immune conditions — some immune-related conditions can influence IgE levels

Why would I need Food Allergy Screening?

  • Notice symptoms after eating specific foods
  • Have ongoing skin reactions such as rashes or hives
  • Experience regular digestive discomfort
  • Have unexplained respiratory symptoms
  • Suspect a food sensitivity affecting your day-to-day life
  • Want a broad screen for peace of mind

Food Allergy Screening Blood Test FAQs

What blood test checks kidney function?2026-02-18T11:59:50+00:00

A kidney function blood test typically measures creatinine, eGFR, urea, sodium, and potassium. These markers together give a clear picture of how well your kidneys are filtering waste and maintaining balance in your body.

What is a normal eGFR level?2026-02-18T12:00:17+00:00

A normal eGFR is 90 or above. Values between 60 and 89 may be normal depending on age and other factors, but an eGFR below 60 for three months or more can indicate chronic kidney disease. Your healthcare provider will interpret your eGFR in the context of your overall health.

Can I test my kidney function at home?2026-02-18T12:00:42+00:00

Some at-home finger-prick blood tests are available, but kidney function testing is most accurate when performed by a qualified professional using a venous blood sample. Our clinic offers fast access to professional testing with results reviewed by qualified clinicians.

Do I need to fast before a kidney function test?2026-02-18T12:01:04+00:00

No. You do not need to fast before a kidney function blood test. You can eat and drink normally before your appointment.

What are the symptoms of kidney problems?2026-02-18T12:01:30+00:00

Early kidney disease often has no symptoms. As kidney function declines, symptoms may include swelling (particularly around the eyes, hands, or ankles), fatigue, changes in urination (frequency, colour, or amount), persistent lower back pain, high blood pressure, or nausea. Many people only discover kidney problems through routine blood testing.

How often should I test my kidney function?2026-02-18T12:01:53+00:00

If you have diabetes, high blood pressure, or a family history of kidney disease, annual testing is recommended. If you have been diagnosed with chronic kidney disease, your healthcare provider will recommend more frequent monitoring.

What does high creatinine mean?2026-02-18T12:02:16+00:00

High creatinine levels in the blood suggest that your kidneys are not filtering waste effectively. Creatinine is a waste product from muscle activity, and healthy kidneys remove it from the blood. Elevated creatinine is one of the key indicators of reduced kidney function.

Can kidney function improve?2026-02-18T12:02:43+00:00

In cases of acute kidney injury, kidney function can sometimes recover with treatment. Chronic kidney disease, however, is usually progressive and cannot be reversed. Early intervention can slow or stop further decline, which is why regular monitoring is important.

Can dehydration affect kidney test results?2026-02-18T12:03:38+00:00

Yes. Dehydration can temporarily elevate creatinine and urea levels. If you are dehydrated when your blood is taken, your results may not reflect your true kidney function. Make sure you are well-hydrated before your test.

Should I stop taking medication before the test?2026-02-18T12:03:59+00:00

Do not stop any prescribed medication before your test unless specifically instructed by your doctor. Some medications can affect kidney function, but stopping them without medical advice can be harmful. Bring a list of all medications you take to discuss with your healthcare provider when reviewing your results.
