Tick identification and testing services
MDPH does not offer tick identification or tick testing. While testing ticks can provide useful information, there are some notable issues:
- Positive or negative results from a tick or ticks attached to a person do not provide definitive evidence that that you were exposed or not exposed
- Most people diagnosed with a tick-borne disease are not aware that they have been bitten by a tick and the tick you do find may not be the only tick that bit you
- It is possible to be bitten by a tick carrying a disease and not be infected with that disease, depending on many factors, including how long the tick was attached to you
If you choose to have a tick tested, it is important to keep in mind the following:
- Although probably uncommon, laboratory tests performed on the ticks may produce either false positive or false negative results, and depending on the laboratory and service you request, may not be tested for all infections ticks can carry. Therefore, even if you receive a negative result, you should still monitor yourself for the appearance of rash, fever or other signs and symptoms and immediately seek the advice of a health care provider if they occur.
- If someone has been infected by a tick bite, signs and symptoms may occur even before the results of tick testing are available. You should not wait for tick testing results before seeking medical advice if you feel sick.
- A positive test on a tick is not an automatic indication that treatment is needed or that you will get sick. A positive test indicates that the tick was infected but not that the tick was successful in spreading the infection to the person bitten. Any positive test results should be discussed with your health care provider who will work with you to determine the best course of action based on:
- Your likelihood of an exposure to a tick-borne disease
- When the tick bite occurred
- The presence or absence of signs or symptoms
- Other factors relative to your particular situation
- Tick testing does provide general information about risk to individuals and populations exposed to ticks in particular geographic areas. The University of Massachusetts Laboratory Of Medical Zoology makes their test results available to the public, free of charge, through the Tick-Borne Disease Network Passive Surveillance Database. The name and address of individuals that send ticks in is always kept confidential, but the information about where the tick was found and what pathogens it carried is of great value to the public and agencies trying to track tick-borne diseases.
