Blood Type Test Kit - Group A B O and Rhesus D

No. Treat it as personal information only. Hospitals always type blood themselves before a transfusion, and pregnancy care relies on laboratory typing. This test is for your own knowledge, not as an official record.

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.

Rhesus D is a protein some people carry on their red blood cells (RhD positive) and some do not (RhD negative). Combined with your ABO group it gives one of the eight common blood types, such as O positive or A negative.

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.

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.

The Control circle should stay smooth. If it clumps, the test has not run correctly and the result cannot be relied on. Repeat with a fresh card.

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.

Not exactly. Blood type is inherited from both parents, so knowing yours narrows the possibilities but rarely gives a single answer. Both parents' types are needed even to predict a range.

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.

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.

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.

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.

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.

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.

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.
