I have the bull's-eye rash. Do I need a blood test first?
No — and waiting for one is the commonest mistake. The rash is diagnostic on its own and treatment should start immediately.
Early blood tests are frequently negative because antibodies take weeks to develop.
My test was negative. Does that rule it out?
Not in the first few weeks. If suspicion is high, the test is repeated four to six weeks later.
Antibodies take time. A negative test early in the illness is a timing problem, not an answer.
Should I have antibiotics after any tick bite?
Not routinely in the UK. Most bites do not transmit infection.
Watch the site for six weeks and act if an expanding patch appears.
Does the rash always look like a bull's-eye?
No. Many are uniformly discoloured with no central clearing.
What matters is that it expands over days and is neither itchy nor painful — not whether it has rings.
How should I remove a tick?
Fine-tipped tweezers, grasp close to the skin, pull steadily upward. No twisting.
Never burn it or smother it in Vaseline — that can make it regurgitate into the wound and increases the risk.
Part of it is still in my skin. What now?
Leave it. Remaining mouthparts cause only a minor local reaction and work their own way out.
Digging for them causes more damage than they do.
Is chronic Lyme disease real?
Some people have genuinely persistent symptoms after treated Lyme disease, and that is recognised. What is not supported is diagnosing it on unvalidated tests, or treating it with months of antibiotics.
Prolonged intravenous antibiotics cause documented harm and have not been shown to help. Persistent symptoms deserve a proper reassessment, not an indefinite course.
Should I use a private overseas Lyme test?
No. Several produce high rates of false positives and are not validated.
Use UKHSA reference laboratory testing, which is available on the NHS and is the testing the guidance is built on.
Can I catch it from another person or my dog?
Not from a person — it is not contagious.
Not directly from a dog either, though dogs bring ticks into the house, so check them after walks.
