Question by coolquit2: What do they do when they test you for Lyme disease?
I got bitten by a tick and I’m going to the doctor. I’m wondering if he tests me for Lyme disease, what does he do? I’m not sure if it was a deer tick or not, but I got the tick in an area where deer are, so I’m a little scared. Wish me Luck. Thanks.

The test is used to determine if your blood has made antibodies to the bacterium that causes Lyme disease. The infection affects many body systems, and in many patients starts with a “bulls-eye” rash at the site of the bite, and flu-like symptoms. The disease can progress and eventually cause a variety of chronic symptoms, including inflammation of the heart, arthritis, and central nervous system disease, including meningitis.
But because the symptoms of Lyme disease vary from person to person, and because antibodies to the bacterium do not appear until 3-6 weeks after the tick bite (although the skin lesion may appear within 3 to 30 days), the infection is difficult to diagnose. At this point, a blood test can be used to detect levels of antibodies, immunoglobulin M (IgM) and immunoglobulin G (IgG), that develop against the Borrelia burgdorferi bacterium.
This test, however, can also detect antibodies to other bacteria. Therefore, if the test is positive, an additional test, called a Western Blot, is often required to confirm the presence of specific antibodies to the bacterium that causes Lyme disease. Lastly, A DNA-based test based on the polymerase chain reaction (PCR) may also be done and is even more sensitive; it is used to detect the genetic material of the infecting bacteria. Taken together, these tests will help your doctor confirm a diagnosis. Once the diagnosis is made, your doctor will recommend appropriate treatment.
