Tick Removal Procedure

• If possible, have someone else remove the tick from you.
• Use tweezers or forceps rather than your fingers.
• If you must touch tick use a tissue or gloves to protect your hand.
• Grasp the tick's mouthparts as close to the skin as possible.
• Gently pull the tick straight out, steadily and firmly. Do not twist or jerk the tick.
• If mouthparts of the tick break off and remain in your skin, consult your physician.

• Place tick into clean capped container or a zip-lock plastic bag. Place a piece of cotton or tissue moistened with tap water into the container with the tick. (Note: do not use alcohol, formalin or other liquids. Do not stick tick to scotch tape. These materials make testing for the Lyme organism unsatisfactory.)
• Bring or ship tick to the laboratory as soon as possible.
• Complete a laboratory 'TICK IDENTIFICATION FORM" or supply the following information:
• Name, address and birth date of person bitten.
• Location of the bite (arm, neck, etc.)
• Date tick removed.
• Estimated duration of time tick was attached (i.e. 4hrs, 24hrs, etc.
• Geographical location (what city, park, etc.) tick was obtained.
• Phone number, name and address of person to receive report.
• Any obvious symptoms.
