Tick Identification

Tick identifications are a service for residents of New Hampshire only, and are provided free of charge by the New Hampshire Department of Agriculture, Markets & Food, Division of Plant Industry.

We will identify the species of the submitted tick to the degree possible. We do not, however, test ticks for disease causing agents, such as the Lyme disease pathogen. To have a tick tested for disease causing agents, you can:

  1. Take the tick to your doctor. They can submit it to Quest Diagnostics Laboratories for you.
  2. Analytical Services Inc. in Vermont.
  3. UMass Extension. They will identify the tick, test for Lyme, and for babesiosis and anaplasmosis upon request.

This information is provided for your convenience. It is neither a recommendation nor an exhaustive list of the organizations that provide these diagnostic services.

To submit a tick for identification only, please fill out the form and either mail the form with the specimen to the Division (the address is at the top of the form) or bring it to the New Hampshire Health and Human Services Building (29 Hazen Drive) in Concord and leave the specimen and paperwork in the Department of Agriculture identification drop box (the staff at the front reception window can direct you). Care should be taken with the specimen to ensure it arrives in a condition that enables identification. If sending the sample by mail, place the specimen in a vial or crush-proof container.
