This alcohol breath detection test may use one of two common technologies: a single-use colorimetric chemical pad or an electronic sensor (semiconductor/fuel cell) with a replaceable mouthpiece. Materials typically include a sealed test cartridge, reactive test strip or sensor module, plastic housing, and a user mouthpiece.

1. Read all instructions supplied with the test before use.
2. Wait at least 15 minutes after drinking, smoking, eating or using mouthwash to avoid false readings.
3. Remove the test from its sealed pouch and attach the mouthpiece if applicable.
4. Take a deep breath and exhale steadily into the mouthpiece for the recommended time (typically 3–5 seconds) or follow the device prompts for digital models.
5. Read the result according to the product type: color change on a strip (match to reference chart) or numerical BAC reading on a digital display.
6. Dispose of single-use components responsibly; follow local guidelines for electronic device disposal for reusable models.

Designed for adults who need quick alcohol screening: drivers, ride-share drivers, hospitality staff, employers performing workplace safety checks, event staff, and individuals monitoring sobriety. Not intended for diagnosis of alcohol use disorders; it is a screening tool to indicate the presence of alcohol.

Caution: This product is a screening device and not a definitive medical diagnostic tool. Avoid interpreting a single test as legal proof of intoxication. Results can be affected by environmental factors, recent consumption, certain medications and mouthwash. Do not use to determine fitness for duty in regulated environments without confirmatory testing.

Storage: Keep sealed in original packaging until use. Store in a cool, dry place away from direct sunlight and extreme temperatures. Do not freeze. Check expiry date — do not use expired tests. For reusable electronic models, follow manufacturer guidance for calibration and battery care.
