Key takeaways
A structured assessment
Lyme disease can resemble other illnesses, and not everyone remembers a tick bite. The likelihood of exposure in a relevant place and season helps a clinician judge what findings mean.
Tests support the assessment
Recommended antibody testing follows defined national algorithms. Very early testing may be negative, while antibodies can remain detectable after an infection has resolved, so context remains essential.
