Who it is for
Is this allergy test right for you?
Allergy symptoms are easy to mistake for a cold, the flu or a sore throat. People with an allergic sensitivity — to pollen, animal hair, feathers or certain foods — carry abnormally high levels of IgE antibodies in their blood. An allergy test at home gives you a first answer in ten minutes. People use it when they notice:
- Repeated sneezing or a runny nose around dust or animals
- Watery, itchy eyes
- Skin redness or a rash
- Swelling after eating a particular food
- A “cold” that comes back every spring
Allergies can start at any age. Children, teenagers and adults can all develop an allergic sensitivity, and it runs in families.
- Family history of allergyTesting is especially worthwhile when symptoms appear
- Seasonal symptomsThe same complaints at the same time each year
- Symptoms around petsSneezing or itching near a cat or dog
- Reactions to foodSwelling or a rash after certain meals
What it measures
What this IgE allergy test tells you, and what it does not
It tells you
- Whether the total IgE in your blood is above 100 IU/mL, determined against the WHO reference
- A raised IgE points to an allergy or an allergic predisposition — it helps tell allergy from infection
- From a fingertip blood sample, in ten minutes, at home
It does not tell you
- What you are allergic to. Finding the allergen is the next step, with a doctor or an allergist
- The exact IgE number. It answers above or below one threshold
- Anything reliable if you take anti-IgE antibody treatment, corticosteroids or immunosuppressants: they change the result
- Whether a food intolerance is behind your symptoms. This test does not measure that

How it works
Five steps, about fifteen minutes
01
Prepare the lancet
Very important: do not touch the trigger. Twist the grey protective cap off, never pull it. Keep turning until it comes away.
02
Take a blood sample from your fingertip
Very important: use the pipette correctly — lightly touch the drop of blood with the pipette’s tip, not the skin, do not squeeze the bulb, fill to the line.
03
Put the blood into the sample well
Press the pipette bulb to release the blood into the sample well. Then wait 30 to 40 seconds until it is absorbed.
04
Add exactly 4 drops of diluent
Very important: add the diluent only after the 30 to 40 seconds. Hold the vial upright and add exactly four drops, 2–3 seconds apart.
05
Read the result after 10 minutes
Not after 15. Set a timer.
Instructions for useWatch the video demonstration
On the clock: the ten minutes, step by step
- Drop in
Blood from the pipette into the sample well.
- Wait, then diluent
Not before 30–40 seconds. Then exactly four drops, 2–3 seconds apart.
- Colour moves
Lines begin to form. Not readable yet.
- Read
Read the result now, in good light.
- Stop
Do not interpret the result after 15 minutes.
Your result
How to read your allergy test result
Two lines means your IgE is raised. One line means it is in the normal range. A faint second line still counts as a line. The pictures below show each result.
IgE raised positive
Both C and T lines are visible. IgE is above 100 IU/mL; you may have an allergy or an allergic predisposition. See your doctor.
Normal negative
Only the C line is visible. IgE is in the normal range; no allergic sensitivity detected.
Invalid repeat
No C line. The result cannot be read. This happens most often when the diluent is added before the blood has been absorbed. Repeat with a new test and a fresh blood sample, and wait the full 30 to 40 seconds before you add the diluent.
A faint T line still counts as a line — the colour and intensity of the lines do not matter, only that they are homogeneous and complete. Read at 10 minutes; do not interpret the result after 15. The pictures are for illustration purposes; the actual lines may differ in intensity.
Next step
What to do with your result
If your IgE is raised
See your doctor and show the result. They will decide whether further tests are needed or refer you to an allergist, who can find the substance that causes the reaction and prescribe a treatment that fits.
If your IgE is normal but the symptoms stay
An allergy is unlikely. Repeated sneezing, a rash or watery eyes can also come from an infection. If the symptoms persist, see your doctor.
The technology
What happens inside the test device
All of it happens on a paper strip inside the test device, in ten minutes.
- The sample moves
The drop of blood and the diluent travel along the strip by capillary action. No pump, no power.
- Antibodies find IgE
The test uses a pair of antibodies that specifically detect immunoglobulin E (IgE).
- The T line
Above 100 IU/mL, a coloured line appears at T. Below that, none.
- The C line
The C line captures the excess reagent. A line at C means the test worked. No C line, no result.
This test has been used by professionals in hospitals and laboratories for more than 20 years. It gives one answer — above or below the threshold — not a number.

Questions
Asked before ordering
How accurate is an allergy test at home compared with the laboratory?+
In the evaluation studies, the test agreed with laboratory reference methods in 97.03 % of cases (95 % CI 91.15–99.61 %). The difference is what you get back: the laboratory reports an IgE number and can test for single allergens, this test tells you whether your total IgE is above or below 100 IU/mL. For a first answer that is enough; an allergist can then look for the cause.
Does the finger prick hurt?+
It is a brief prick. Wash your hands with warm water first, massage the finger towards the tip for 10 to 15 seconds, and prick the side of the fingertip. The needle retracts into the lancet straight away.
Does it tell me what I am allergic to?+
No. It measures total IgE, the antibody class behind allergic reactions. A raised result means you may have an allergy or an allergic predisposition; an allergist then tests for the specific substance.
Can children use it?+
Not for children under six. For an older child, ask your doctor first whether an IgE check makes sense.
Which medicines affect the result?+
Anti-IgE antibody treatments, corticosteroids and immunosuppressants can make the result incorrect. If you take any of those, speak to your doctor before testing.
What if I cannot get enough blood?+
Massage the finger gently from its base towards the tip, with a light squeeze-and-release motion, until a large drop forms. Then fill the pipette to the line. Every kit has a spare lancet and pipette for a second attempt.
The lancet did nothing when I pressed it+
A lancet works only once. If the grey protective cap was pulled off by force instead of twisted, the lancet may already have been triggered. Take the spare lancet, give the cap a quarter turn, keep turning until it comes away, then press the lancet firmly against the side of the fingertip and press the trigger button.
Why did I get an invalid result?+
The most common causes are an incorrect amount of blood, adding the diluent before the blood was absorbed, or a test device that was exposed to moisture before use. A test device can be used only once, so repeat with a new test: fill the pipette to the line, wait 30 to 40 seconds, then add four drops. Write to us and we replace the test.
How do I dispose of the lancet?+
The needle retracts into the lancet body after use, so all components can go in household waste. If your pharmacy collects sharps separately, use that; it is the tidier option.
