Topic Overview

Misdiagnosis of
Lyme disease is common.

The bacteria that cause the illness are hard
to detect with current lab tests.

  • People often test positive for Lyme disease
    when in fact they have a different
    bacterial illness.
  • People may test positive because
    they were infected with the Lyme disease bacteria at some point during their lives, but the
    infection may not be active and may not cause any illness.
  • People may test
    negative when they actually have been infected.

Symptoms of Lyme
disease sometimes closely resemble those of other illnesses.
