A self-test for Group A Streptococcus (Strep A) from a throat swab you take yourself. In 5 minutes it shows whether a sore throat may be caused by Strep A bacteria, so you know whether to see a doctor promptly.
Why test?
Most sore throats are caused by viruses and do not need antibiotics. Group A Streptococcus is the most common bacterial cause of throat infection (pharyngitis, tonsillitis) and is treated by a doctor with antibiotics. The two are hard to tell apart by symptoms, and a throat culture takes 24–48 hours or longer. Typical signs of Strep A: a sudden sore throat and pain when swallowing, fever, red and swollen tonsils (sometimes with white patches), swollen neck glands and, in children, tummy ache, nausea or vomiting. A cough, runny nose or hoarse voice point more often to a virus.

Common questions
What does a positive result mean?
Two lines (C and T) mean that Strep A antigen was detected. Contact your doctor, who will decide on treatment.
The result is negative but my throat still hurts. What now?
The cause is more likely a virus. If symptoms persist or get worse, see a doctor. The test can be repeated after 1–2 days.
How do I take the swab?
Stand in front of a mirror, tilt your head back slightly and press your tongue down with a spoon. Rub the swab over one or both tonsils or the back of the throat without touching the tongue, cheeks or teeth.
Rapid tests are intended for preliminary screening and do not replace a doctor’s consultation.

Questions about this test
Read the instruction leaflet in the pack before you start. Collect your sample as described, apply it to the test, and read the result within the time stated in the leaflet. Do not read the result after that time.
The accuracy shown on this page comes from the manufacturer's validation data. No self-test is 100% accurate, so a result is an indication, not a diagnosis.
The test is invalid. Do not interpret the result. Repeat the test with a new one and follow the leaflet carefully.
Speak to a doctor or pharmacist. A self-test does not replace a medical consultation, and a negative result does not always rule out a condition, especially if you have symptoms.
Store it as described in the leaflet and keep it sealed until use. Do not use a test after the expiry date printed on the pack.
Delivery is free on orders over €30 (€50 to Latvia and Estonia). Orders are dispatched from Vilnius within 24 hours on business days. Delivery is usually 1-3 business days in Lithuania and 2-5 business days in Latvia and Estonia. Shipping policy
