Constant sneezing: common allergy triggers
Five sneezes in a row before breakfast, every day, is not a cold. It is often your nose reacting to something it meets again and again. Our test measures IgE sensitisation to 300 allergens and allergen components, so you can see which ones your immune system responds to.
Sneezing, colds and allergies
A cold usually runs its course in a week or so and comes with a sore throat or feeling run down. Allergic sneezing tends to come in fits, with a clear runny nose and itching in the nose, throat or eyes, and it keeps coming back in the same places or the same months.
The medical name is allergic rhinitis. Hay fever is the seasonal version. The year-round version is just as common and gets overlooked, because people assume a permanent sniffle is normal.
Common patterns
Look at when and where you sneeze most.
- First thing in the morning, after making the bed: house dust mite.
- Outdoors on dry, windy days in spring: tree pollen such as birch and alder.
- Early summer, especially after mowing: grass pollen.
- August and September: mugwort and ragweed.
- Visiting friends with pets, or riding stables: cat, dog, horse.
- Cellars, damp walls, gardening in autumn: mould spores.
What the test shows
From a finger-prick sample, the lab checks IgE to 300 allergens and allergen components: tree, grass and weed pollens, animals, mites, moulds, foods and more. Your lab report gives each a measured value and class, from Negative to Very high.
Many people with sneezing show more than one sensitisation, for example grass plus dust mite. That explains why symptoms do not fit a single neat season. Remember that sensitisation is not proof of cause; your doctor can match the results to your history.
Sneezing that is not allergic
Bright light, cold air, spicy food, perfume and smoke can all set off sneezing without any IgE involved. This is called non-allergic rhinitis, and an allergy test will not show it. If little or nothing comes back raised and you still sneeze a lot, mention that to a doctor.
When to see a doctor first
See a doctor if sneezing comes with fever, facial pain, bloody or one-sided discharge, or if symptoms last for weeks and disturb your sleep or daily life. If you also notice wheezing, chest tightness or shortness of breath, get checked rather than waiting for test results.

Questions
Why do I sneeze more in the morning?
Morning sneezing is common with house dust mite, because you have spent the night close to mattresses and pillows. Pollen counts can also be high in the early morning. The test checks both.
Can you develop sneezing allergies as an adult?
Yes. Sensitisation can appear at any age, and new symptoms often start after a move, a new pet or a change of job. The test shows your current IgE sensitisation pattern.
Will the test tell me if it's a cold or an allergy?
No. It measures IgE to allergens, not infections. It can show whether you are sensitised to common airborne allergens, which helps your doctor judge whether allergy is a likely explanation.
