Why Laboratory Analysis of Ticks is Important
Understanding Tick-Borne Diseases
Common Pathogens Tested
Submitting a tick for diagnostic evaluation typically involves forwarding the specimen to a public‑health, university, or veterinary diagnostic laboratory equipped to perform molecular or culture‑based assays. These facilities routinely screen for a defined group of microorganisms that pose the greatest risk to human and animal health.
The most frequently tested agents include:
- Borrelia burgdorferi – the bacterium responsible for Lyme disease.
- Anaplasma phagocytophilum – causative agent of human granulocytic anaplasmosis.
- Ehrlichia chaffeensis – pathogen of human monocytic ehrlichiosis.
- Rickettsia rickettsii and related spotted‑fever group rickettsiae – agents of Rocky Mountain spotted fever and other rickettsial illnesses.
- Babesia microti – protozoan that produces babesiosis.
- Powassan virus – tick‑borne flavivirus associated with encephalitis.
- Tick‑borne encephalitis virus (where endemic).
- Francisella tularensis – bacterium causing tularemia, occasionally screened in regions with known exposure.
Testing protocols often combine polymerase chain reaction (PCR) panels, serologic assays, and, when appropriate, culture techniques to detect these organisms. Laboratories may also include emerging or region‑specific pathogens upon request, ensuring comprehensive assessment of the tick’s infectious potential.
Early Detection and Treatment Benefits
Submitting a tick to a qualified diagnostic laboratory enables identification of pathogenic agents before symptoms appear in the host. Laboratory testing determines the presence of bacteria, viruses, or parasites carried by the arthropod, providing concrete evidence for risk assessment.
Early identification of a pathogen allows clinicians to initiate therapy at the first sign of infection. Prompt treatment reduces the likelihood of severe complications, shortens disease duration, and lowers the probability of long‑term sequelae. Timely intervention also limits the spread of tick‑borne illnesses within a community by reducing the number of infectious hosts.
Benefits of early detection and treatment include:
- Faster symptom resolution
- Decreased need for aggressive or prolonged medication courses
- Lower risk of organ damage or chronic disease
- Reduced healthcare costs associated with advanced disease management
- Improved patient outcomes and quality of life
Accurate laboratory results guide evidence‑based therapeutic decisions, ensuring that antimicrobial or antiviral agents target the specific organism present. This precision prevents unnecessary drug exposure and supports antimicrobial stewardship.

The cumulative effect of routine tick submissions is a robust surveillance infrastructure capable of early detection of pathogens such as Borrelia, Anaplasma, and Powassan virus. Continuous data acquisition enables predictive modeling, informs vector‑control strategies, and supports evidence‑based public health interventions.
Preparing the Tick for Submission
Safe Removal Techniques
Proper Tools and Methods
Submitting a tick for diagnostic evaluation requires reliable collection instruments and a clear workflow to ensure accurate identification and pathogen detection. Use fine‑point tweezers or a sterile, single‑use tick removal tool to grasp the tick as close to the skin as possible, avoiding compression of the abdomen. Place the intact specimen in a labeled, sealable container—preferably a 1.5‑ml microcentrifuge tube or a small, sterile plastic vial—filled with 70 % ethanol for preservation or kept dry if the receiving laboratory specifies live specimens. Include a written label with collection date, host species, geographic coordinates, and collector’s contact information.
The next step involves dispatching the sample to an accredited facility equipped for arthropod analysis. Suitable destinations include:
- State or provincial public health laboratories that operate vector‑borne disease programs.
- University or research institution laboratories with entomology or microbiology departments recognized by the Centers for Disease Control and Prevention (CDC) or equivalent national agencies.
- Commercial diagnostic companies certified for tick testing, provided they accept specimens from the region of origin.
Before shipment, verify the laboratory’s submission guidelines, which typically outline acceptable preservatives, packaging requirements, and any required permit documentation. Use a courier service that offers temperature‑controlled transport if live ticks are needed, and insure the package against loss. Retain a copy of the tracking number and the laboratory’s receipt confirmation for follow‑up inquiries.
Avoiding Crushing or Damaging the Tick
When a tick is collected for diagnostic testing, preserving its integrity is essential for accurate laboratory results. Damage to the specimen can obscure morphological features, reduce DNA quality, and compromise pathogen detection.
Handle the tick with fine‑point tweezers or a small, stiff brush. Grip the body close to the mouthparts, avoiding pressure on the abdomen. Do not squeeze, twist, or pull abruptly; a steady, gentle motion releases the tick without crushing its exoskeleton.
Place the intact specimen into a clean, sealable container. Preferred options include:
- A sterile 1.5‑ml microcentrifuge tube containing a small volume of 70 % ethanol (enough to cover the tick but not submerge it completely).
- A dry, labeled paper envelope if the laboratory specifies dry transport; include a desiccant packet to prevent moisture buildup.
- A sealed plastic vial with a breathable membrane if live culture is required, ensuring the tick remains unharmed.
Label the container with collection date, location, host species, and any relevant clinical information. Secure the label to prevent loss during transit.
Transport the package promptly, using a insulated container if ambient temperature may exceed recommended limits. Avoid agitation; place the specimen in a stable position within the carrier.
By following these steps, the tick reaches the appropriate testing facility in a condition suitable for morphological examination, molecular assays, and pathogen identification.
Storage and Packaging
Recommended Containers
Ticks destined for diagnostic testing must be placed in containers that preserve morphology, prevent leakage, and comply with transport regulations. The choice of container depends on the intended analysis (morphological identification, molecular testing, or pathogen culture) and the condition of the specimen (alive or dead).
- Rigid, leak‑proof plastic vials with screw caps, pre‑filled with 70 %–95 % ethanol, are suitable for dead ticks destined for DNA extraction or microscopic examination. Ethanol concentration should be sufficient to prevent desiccation but low enough to avoid DNA degradation.
- Small, ventilated paper envelopes or breathable mesh pouches are recommended for live ticks that require observation of feeding behavior or culture. The envelope must be sealed with tape to avoid escape while allowing airflow.
- Cryogenic transport tubes (e.g., polypropylene screw‑cap tubes) containing dry ice or liquid nitrogen are required when preserving RNA or viable pathogens. Tubes must be rated for low‑temperature use and sealed tightly to prevent condensation.
- For bulk submissions, a sturdy cardboard box with internal dividers separates individual vials or envelopes, reducing cross‑contamination and damage during shipment.
Each container must bear a durable label indicating species (if known), collection date, geographic location, collector’s name, and a unique identifier. Labels should be printed on waterproof material and affixed with permanent adhesive. A separate data sheet, matching the identifiers on the containers, should accompany the shipment.
Transport containers must meet regulations for biological specimens: secondary containment (e.g., sealed plastic bag) inside a rigid outer case, absorbent material for potential leaks, and clear marking of hazardous material if ethanol is used. Packages should be dispatched promptly to the receiving laboratory, with temperature control maintained according to the preservative method.
Temperature and Moisture Control
When sending tick specimens for diagnostic testing, maintaining defined temperature and moisture conditions preserves organism integrity and ensures reliable results.
Ticks remain viable for up to 48 hours if stored at 4 °C ± 2 °C. Temperatures above 10 °C accelerate degradation; temperatures below 0 °C cause mortality and alter pathogen load. Use refrigerated containers with validated temperature monitors; avoid direct contact with ice to prevent freezing.
Relative humidity should stay between 70 % and 85 % to prevent desiccation. Place ticks in a breathable, moisture‑retaining medium (e.g., damp cotton gauze) inside a sealed, but not airtight, container. Include a saturated salt solution or humidifier pouch to maintain humidity levels during transit.
Packaging protocol:
- Place specimens in a sealed, labeled vial containing a moist substrate.
- Insert the vial into an insulated cooler with a refrigerated gel pack.
- Attach a data logger that records temperature at 5‑minute intervals.
- Ship via overnight courier; total transit time must not exceed 24 hours.
Receiving laboratories typically require:
- Documentation of temperature and humidity readings from the data logger.
- Confirmation that the cooler remained within the specified temperature range.
- Clear labeling of species, collection date, and intended analysis.
Adhering to these parameters minimizes sample loss, supports accurate pathogen detection, and aligns with standard operating procedures of veterinary and public‑health diagnostic facilities.

Complete the verification process before sending the specimen to avoid claim denials and unexpected out‑of‑pocket expenses.
Prevention of Tick Bites
Repellents and Protective Clothing
Repellents and protective clothing reduce the likelihood of tick attachment, thereby decreasing the number of specimens that need laboratory evaluation. Effective repellents contain DEET (20‑30 %), picaridin (20 %), or IR3535 (20 %). Permethrin‑treated clothing provides continuous protection; a single application remains active for up to six weeks of regular wear. When selecting attire for tick‑infested environments, choose long‑sleeved shirts, long trousers, and gaiters that fully cover the lower legs. Tuck pant legs into socks or boots to eliminate gaps.
If a tick is discovered on a person or animal, submit the specimen to an authorized diagnostic facility. Acceptable destinations include:
- State or provincial health department laboratories.
- University veterinary or entomology departments with accredited tick‑testing programs.
- Federal agencies such as the Centers for Disease Control and Prevention (CDC) or the National Institutes of Health (NIH) reference labs.
Specimens should be placed in a sealed, ventilated container with a moist cotton ball to maintain viability. Include a short note describing the host, attachment site, and date of collection. Prompt submission—ideally within 24 hours—ensures accurate identification and pathogen detection.
Tick Checks and Yard Maintenance
Tick checks begin with a thorough examination of the body after outdoor exposure. Remove any attached tick with fine‑pointed tweezers, grasping close to the skin and pulling upward with steady pressure. Preserve the specimen in a sealed container, such as a small vial or zip‑lock bag, and label with date, location, and host information. For diagnostic testing, forward the sample to a qualified laboratory; typical destinations include the state or county health department’s vector‑borne disease unit, university‑affiliated entomology labs, or the Centers for Disease Control and Prevention’s tick testing program. Contact the relevant agency to confirm submission requirements, packaging guidelines, and any associated fees.
Yard maintenance reduces the likelihood of tick encounters. Implement the following practices:
- Keep grass trimmed to a maximum of 3 inches; mow regularly during peak tick season.
- Remove leaf litter, tall weeds, and brush from the perimeter of the property.
- Create a 3‑foot wide barrier of wood chips or gravel between lawn and wooded areas.
- Apply approved acaricide treatments to high‑risk zones, following label instructions.
- Encourage wildlife‑deterring fencing to limit deer ingress, a primary tick host.
Regularly inspect pets for ticks and treat them with veterinarian‑recommended preventatives. Document all findings and submit any collected ticks promptly to the designated laboratory to facilitate accurate identification and pathogen testing.
