When to see your GP

You should see your GP if you develop any of the symptoms described above after being bitten by a tick, or if you think you may have been bitten. Make sure you let your GP know if you've spent time in woodland or heath areas where ticks are known to live.

Diagnosing Lyme disease is often difficult as many of the symptoms are similar to other conditions. A spreading rash some days after a known tick bite should be treated with appropriate antibiotics without waiting for the results of a blood test.

Blood tests can be carried out to confirm the diagnosis after a few weeks, but these can be negative in the early stages of the infection. You may need to be re-tested if Lyme disease is still suspected after a negative test result.

In the UK, two types of blood test are used to ensure Lyme disease is diagnosed accurately. This is because a single blood test can sometimes produce a positive result even when a person doesn't have the infection.

If you have post-infectious Lyme disease or long-lasting symptoms, you may see a specialist in microbiology or infectious diseases. They can arrangefor blood samples to be sent to the national reference laboratory run by Public Health England (PHE), where further tests for other tick-borne infections can be carried out.
