The BACtrack® SingleShot™ is a test for alcohol in human breath. It is a disposable screening device for one-time use.
The SingleShot is based on indicator chemistry that changes color in the presence of breath that contains alcohol. See our website for more information on the chemistry of the detector. Detectors are calibrated to turn positive at or above a specific level of alcohol in the breath. This level is called the cut-off. The cut-off is printed on the left side of the detector label. For example, a SingleShot detector labeled 0.08% will turn positive when the breath contains or exceeds 0.08% alcohol.
Alcohol impairs judgement. Do not test yourself or drive if you have been drinking. Someone who has not been drinking should help conduct the test and read the result.
Do not use the detector if the glass tube containing crystals is broken or the crystals are not yellow before you begin step one of the instructions.
SingleShot results should not be interpreted by readers who are color-blind, visually impaired, or under the influence of alcohol or any other substance that may impair their vision or judgement.
SingleShot result is best viewed under white light (incandescent, fluorescent or indirect sunlight). It may be hard to read SingleShot results under certain streetlights or under dim lighting. Under yellow streetlights (sodium vapor), green colors may look gray-green; blue colors may look gray-white. Under blue-white streetlights (mercury vapor) yellow may look amber-green. A flashlight with an incandescent bulb, held to the side of the detector, may be used to help read the result under these lighting conditions.
Lighting studies were performed following NHTSA (National Highway Traffic Safety Administration) guidelines. SingleShot results were read under 5 lighting conditions. The results met the guidelines except for 1 reading. There was 1 false positive out of 1200 readings of the .04 detector for a sample that did not contain alcohol.
Compare the SingleShot result to the yellow box on this pamphlet or to an unused detector of the same lot number to help you see if the detector has turned GREEN or BLUE indicating a positive result.
Keep out of reach of children. Do not immerse in liquid.
DO NOT EAT the contents of the SingleShot--it contains potassium dichromate, a hazardous chemical. If eaten, induce vomiting and contact your doctor.
The SingleShot should only be used as a screening device and is only an indication of the possible presence of alcohol in the blood of the subject. Although breath alcohol levels have been shown to represent blood alcohol levels, the correlation depends on many factors. The exact level of alcohol in the blood cannot be accurately determined by using the detector.
The detector does not determine or detect the intoxication of the subject. Decision’s and/or actions based on the use of this device by any person shall be at person’s own risk.
A positive result should be taken as a warning that the subject may have detectable alcohol in their system. A positive result should be confirmed by an evidentiary alcohol test before any legal or workplace actions are taken.
There may be times that a person tests negative and later show that he/she is under the influence of alcohol or their judgement had been impaired by alcohol.
