Home Allergy Test Kit: CE marked Prima Allergy Test
The PRIMA Home Allergy Test measures total IgE antibodies in a finger-prick blood sample. IgE is the antibody your immune system produces during an allergic response, and a raised level suggests allergy may be contributing to symptoms such as sneezing, itching, rashes or breathing difficulties. The test screens for a general allergic tendency rather than identifying which allergen is responsible, so it is a useful first step before more specific testing. Everything needed is included and the result develops in about ten minutes, read from the same C and T line format used by professional lateral flow tests. No sample is posted anywhere and no laboratory is involved.
Intended use
For self-testing by adults who want to check whether an allergic response may be contributing to their symptoms, before speaking to a GP or pharmacist.
This is a screening test intended to support, not replace, professional medical advice. Please consult a doctor about your results.
What’s in the box
Everything you need is included — nothing else to buy.
- 1×Test cassette, individually foil-sealed
- 1×Sterile single-use lancet
- 1×Buffer solution
- 1×Disposable pipette
- 1×Alcohol wipe
- 1×Step-by-step instructions
How you do it
No lab, no appointment, nothing to post. Most people finish the sample step in under two minutes.
- 1Wash and warm your hands1 min
Warm hands bleed more easily. Run them under warm water and shake them out.
- 2Prick the side of a fingertip10 sec
The side is less sensitive than the pad. The lancet is spring-loaded, so depth is fixed.
- 3Collect one drop of blood1 min
Use the pipette provided. Wipe the first drop away and use the second.
- 4Add sample and buffer to the cassette30 sec
Follow the exact number of drops in the instructions.
- 5Wait, then read the resultSee pack
Read within the time window stated — reading too late can give a misleading result.
What your result will mean
Worth knowing before you test, not after.
A raised total IgE suggests an allergic response is likely. It does not identify which allergen is responsible or diagnose a specific allergy. A GP can arrange specific IgE or skin prick testing to narrow it down.
A normal total IgE makes a widespread allergic response less likely, but does not rule out a localised or food-specific allergy. If symptoms continue, speak to a GP regardless of this result.
If no line appears at C, the test has not run correctly and the result cannot be relied on — most often because too little sample was added. Contact us and we will replace it.
Questions people ask
Will this tell me what I am allergic to?
No. It measures total IgE, which indicates a general allergic tendency. Identifying the specific allergen needs specific IgE testing or skin prick testing arranged through a GP.
What if the result is positive?
A positive screening result is not a diagnosis — it means further testing is worthwhile. Take the result to a GP, who will arrange a confirmatory laboratory test. Many people who get a positive screening result turn out not to have the condition, because screening tests are deliberately set to catch possible cases rather than to be certain. Finding out early almost always gives you more options, not fewer.
I'm nervous about testing at all. Is that normal?
Yes, and it's the most common reason people put testing off. It can help to know that a test only tells you something that is already true — it doesn't change your situation, it just gives you the chance to act on it. You can also test with someone you trust nearby, and you don't have to read the result alone.
Can IgE be raised for reasons other than allergy?
Yes. Parasitic infections and some other conditions can raise total IgE, and some people with genuine allergies have normal total IgE. It is a screening indicator rather than a definitive answer.
Does the finger-prick hurt?
Most people describe it as a brief sharp scratch, similar to a diabetes blood glucose check. The lancet is spring-loaded so the depth is fixed and controlled. Warming your hands first and using the side of your fingertip rather than the pad usually makes it easier.
How much blood do I actually need?
Usually a single drop — around one to two drops depending on the test. The kit includes a pipette to transfer it, so you don't need to be precise by eye.
What if I make a mistake doing the test?
The most common issue is not getting enough sample, which usually shows up as an invalid result with no control line. If that happens the test hasn't run correctly and the result shouldn't be interpreted — you'll need to order another test to get a valid result. Following the instructions in the pack carefully is the best way to avoid this.
Will the packaging show what I've ordered?
No. Everything is dispatched in plain outer packaging with nothing on the label indicating the contents. Your card statement shows only "Seradiag" and an order number, and our emails never name the tests you've bought.
Are these the same tests a clinic would use?
They are CE marked in-vitro diagnostic tests from established manufacturers, in many cases the same devices used in professional settings. The difference is usually the packaging and the instructions, which are written for self-testing rather than clinical use.
How accurate are the tests?
Accuracy figures are published on each product page, taken directly from the manufacturer's instructions for use. No rapid test is perfect: results can be affected by how and when the test is taken, and by individual biological factors. That is why every result — particularly an unexpected one — should be discussed with a healthcare professional.
Can I return a test if I change my mind?
Yes, if the seal is unbroken — within 14 days. Once a kit has been opened it can't be returned for hygiene reasons, which is a legal exception for sealed health products. Faulty, damaged or expired kits are always refunded, opened or not.
How quickly will it arrive?
Delivery options and timescales are shown at checkout. Orders placed before 2pm on a working day are dispatched the same day. If you need a result quickly, choose a faster delivery option at checkout.
Do I need to send anything to a laboratory?
No. These are self-contained rapid tests that you read yourself at home, usually within 5 to 15 minutes. Nothing is posted anywhere, and we never see or store your results.

Complete the kit
This test uses a finger-prick sample. Spare lancets are worth having in case a first sample doesn’t draw cleanly.
