How do i know if i have lyme?

See details: If you have a history of a deer tick bite and the characteristic bulls-eye rash you probably have lyme disease. Otherwise, there is nothing specific upon which to rely. If the symptoms are compatible and the blood work for lyme is positive then you have the diagnosis. Otherwise, you do not.

Depends: Up to 30% of those with lyme never test positive. Sometimes lyme is a clinical diagnosis. There is a new test, called ispot lyme, which can pick up more cases than the western blot.
