What are Lyme disease tests?
Lyme disease is an infection caused by bacteria carried by ticks. Lyme disease tests look for signs of infection in your blood or cerebrospinal fluid.
You can get Lyme disease if an infected tick bites you. Ticks can bite you anywhere on your body, but they usually bite in hard-to-see parts of your body such as the groin, scalp, and armpits. The ticks that cause Lyme disease are tiny, as small as a speck of dirt. So you may not know you have been bitten.
If left untreated, Lyme disease can cause serious health problems affecting your joints, heart, and nervous system. But if diagnosed early, most cases of Lyme disease can be cured after a few weeks of treatment with antibiotics.
Other names: Lyme antibodies detection, Borrelia burgdorferi antibodies test, Borrelia DNA Detection, IgM/IgG by Western Blot, Lyme disease test (CSF), Borrelia antibodies, IgM/IgG
What are they used for?
Lyme disease tests are used to find out if you have a Lyme disease infection.
Why do I need a Lyme disease test?
You may need a Lyme disease test if you have symptoms of infection. The first symptoms of Lyme disease usually show up between three and 30 days after the tick bite. They may include:
- A distinctive skin rash that looks like a bull’s-eye (a red ring with a clear center)
- Muscle aches
You may also need a Lyme disease test if you don’t have symptoms, but are at risk for infection. You may be at a higher risk if you:
- Recently removed a tick from your body
- Walked in a heavily wooded area, where ticks live, without covering exposed skin or wearing repellent
- Have done either of the above activities and live in or have recently visited the northeast or midwestern areas of the United States, where most Lyme disease cases occur
