Top Things To Know About EverlyWell's Lyme Disease Test

Key Points

  • If you have a “bull’s-eye” rash after a blacklegged tick bit you, receive medical attention and treatment as soon as possible – instead of getting this test (unless your doctor advises you to get a blood test for Lyme disease).
  • Consider taking this test if you’ve been to a part of the United States where Lyme disease occurs, suspect you’ve been exposed to ticks, and are now experiencing symptoms of Lyme disease. You can take EverlyWell’s Lyme Disease Test from the comfort of home.
  • This test uses your immune system’s IgM and IgG antibody response to screen for a Lyme infection.
  • EverlyWell’s Lyme Disease Test can reliably detect a Lyme infection months or years after the infection started.

Thinking about getting EverlyWell’s at-home Lyme Disease Test? If so, we’d like you to be as well-informed about it as possible – so here are the top things you need to know about this test.

1. Experiencing a “bull’s-eye” rash after a blacklegged tick bit you? This test is NOT for you

Lyme disease – caused by bacteria known as Borrelia – is transmitted by blacklegged ticks (also called deer ticks). A very common physical sign of Lyme disease is a round, red rash at least 5 centimeters across. This rash often looks like a “bull’s-eye” or “target,” with a solid red center and outer edge (and clearer skin in between).

This rash occurs in about 70% of people who get a Lyme infection, and usually appears within 3-30 days after the tick bite [1]. So why isn’t EverlyWell’s Lyme Disease Test for you if you’re experiencing this rash?

It’s simply because this rash is – by itself – a strong indicator of Lyme disease. So get medical attention right away if you see this rash on your body – instead of taking this test.

2. Who this test IS for

Ticks that transmit Lyme bacteria are only found in certain regions of the United States:

  • Northeast and Mid-Atlantic (from northeastern Virginia to Maine)
  • North Central states (especially Wisconsin and Minnesota)
  • The West Coast (particularly northern California)

So EverlyWell’s at-home Lyme Disease Test may be ideal for you if:

  • You’ve lived in or traveled to the parts of the country listed above, and
  • You’ve been in places where ticks live (such as wooded areas and lawns), and
  • You are now experiencing symptoms of Lyme disease and want to check if you have a Lyme infection.

Here are some common symptoms of Lyme disease:

  • Severe headaches
  • Severe fatigue
  • Recurring pain in muscles, bones, tendons, and joints
  • Facial palsy – which makes it hard to move and control the muscles on at least one side of the face
  • Irregular heart beat
  • Dizzy spells and shortness of breath
  • Short-term memory problems

3. This test is based on your immune system’s antibody response to a Lyme infection (specifically, the IgM and IgG response)

Antibodies are a type of substance your immune system makes when you have an infection. They circulate in the bloodstream and help your immune system fight the infection.

If you get a Lyme infection, your immune system will respond by making two specific kinds of antibodies known as IgM and IgG. EverlyWell’s Lyme Disease Test can help detect Lyme disease because it checks a sample of your blood for these two antibodies.

As a method for disease detection, antibody-based tests are very different than tests based on DNA (since antibodies and DNA are made out of different chemical "building blocks" in your body). So EverlyWell's Lyme Disease Test is not a DNA test for Lyme disease.


4. This test can help you detect Lyme disease months and years after you got infected

EverlyWell’s at-home Lyme Disease Test is based on your immune system's IgM and IgG antibody response to a Lyme infection. Because your body keeps making IgG antibodies if you have a Lyme infection, EverlyWell’s blood test for Lyme can help you discover if you have Lyme disease months and even years after the infection first began [2].

However, your body doesn’t produce significant amounts of these antibodies as soon as the infection starts. Instead, it takes several weeks for these antibodies to accumulate in your bloodstream. So our test will not reliably detect Lyme disease if you’ve only had the infection for a few weeks.
