LymeAlert: The First At-Home Tick Test for Lyme Bacteria

A new at-home kit promises to tell you within 30 minutes whether a tick that bit you carries the bacterium that causes Lyme disease. Called LymeAlert, it is the first direct-to-consumer test that lets users crush a tick in a provided vial, add a solution and dip a test strip to get a yes-or-no result for Borrelia burgdorferi.

Priced at $49.99 and available for pre-order with shipping expected by late August, the kit eliminates the need to mail a tick to a commercial lab or state health department and wait days for an answer. The company was founded by a Boston-based physician assistant, Dr. Dawicki, who saw patients routinely asking whether they could test a tick themselves.

Because blood tests for Lyme detect antibodies that take time to develop, a positive result on a tick can provide an early signal. Dawicki says the goal is not to diagnose the disease in people but to guide decisions on whether to start antibiotics quickly — and, equally, to avoid prescribing them when the tick is clean. The kit is not reviewed by the FDA, because it does not diagnose disease in humans.

What At-Home Tick Testing Means for Patients and Antibiotic Use

The Case for Immediate Answers

Knowing a tick's Lyme status within half an hour, rather than days, could change how early treatment decisions are made. Dawicki notes that many providers currently prescribe antibiotics as a precaution after a tick bite, which contributes to antibiotic resistance. A negative tick test could spare a patient an unnecessary course of drugs, while a positive result could lead to timely treatment and fewer complications.

LymeAlert's test detects the bacteria down to 400 spirochete units, which the developers say is below the 1,000-unit threshold suggested by older animal studies as the amount required to guarantee an infection. However, factors like how long the tick was attached and how many bacteria it actually transmitted still matter. The kit offers a piece of the puzzle, not a final diagnosis.

The CDC's Cautionary Stance

The U.S. Centers for Disease Control and Prevention does not recommend tick testing for Lyme. Its concerns apply equally to home kits: labs use varying standards, a positive result does not mean the bacterium entered your bloodstream, and a negative result cannot rule out a bite from another tick you never found. The CDC advises that people monitor for symptoms such as the classic bull's-eye rash and consult a healthcare provider regardless of a tick-test result.

Beyond Lyme: The Company's Broader Ambitions

LymeAlert is already working on multiplex strips that would detect multiple tick-borne pathogens — such as Rocky Mountain spotted fever and the alpha-gal molecule linked to meat allergy — in a single test, with a launch planned for next summer. The company is also using data on climate, humidity and tick migration to build an AI model that could predict where and when ticks are most likely to carry Borrelia, potentially producing public risk maps.

What to Do After a Tick Bite — and How the Test Fits In

  • If you find an attached tick, you can use the LymeAlert kit to test it immediately. A positive result signals that the tick is carrying B. burgdorferi, but it does not confirm that you have been infected.
  • With a positive tick result, contact your doctor promptly to discuss whether a prophylactic antibiotic course is appropriate. The test result can support that conversation but does not replace clinical judgment.
  • A negative test result does not guarantee you are safe. You may have been bitten by another tick you did not find, or the bacterium may not have been detected. Continue to watch for symptoms such as fever, fatigue or the characteristic rash, and seek medical attention if they appear.
  • The kit is not a substitute for blood-based Lyme testing in people. If you develop symptoms, your doctor may order those tests regardless of the tick's result.
