No
The device description details a chemical reaction that produces a visual color change, which is interpreted by the user. There is no mention of computational processing, algorithms, or learning from data, which are characteristic of AI/ML.
No.
The device is described as a screening device to detect the presence of alcohol in human breath, which is for diagnostic purposes, not for treating a condition.
Yes
The device "semi-quantitatively detect[s] the presence of alcohol in the human breath" and is described as an "in vitro medical device," which aligns with the definition of a diagnostic device that identifies or quantifies a substance.
No
The device description clearly outlines physical components (reagent, plastic bag) and a chemical reaction that produces a visual color change, indicating it is a hardware-based device, not software-only.
Yes, based on the provided information, the Contralco Alcohol Breath Tester is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it is an "in vitro medical device to semi-quantitatively detect the presence of alcohol in the human breath." This directly aligns with the definition of an IVD, which is a medical device intended for use in vitro for the examination of specimens, including blood, tissues, and body fluids, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state or a congenital abnormality. While breath isn't a traditional "body fluid" in the same way as blood or urine, it is a specimen derived from the human body that is being analyzed in vitro (outside the body) to provide information about a physiological state (alcohol presence).
- Device Description: The device works by analyzing a sample of human breath using chemical reactions that occur in vitro within the device itself. The color change of the crystals is a chemical reaction happening outside the body.
- Comparison to Predicate Device: The predicate device listed (K072953; Redline disposable Alcohol Breath Tester) is also an alcohol breath tester, which are typically classified as IVDs.
Therefore, the Contralco Alcohol Breath Tester fits the criteria of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Contralco Alcohol Breath Tester is an in vitro medical device to semi-quantitatively detect the presence of alcohol in the human breath. It is a disposable screening device for one-time use. The detector is available at several detection cut-offs: 0.02, 0.04, 0.05, 0.06, 0.08, and 0.10 relative percent Blood Alcohol Concentration (BAC). The device is used only as a screening device and is only an indication of the possible presence of alcohol in the blood of the test subject.

Device Description
The Contralco Alcohol Breath Tester is a visual qualitative test for alcohol in human breath. The Tester contains chemicals that change color in the presence of alcohol vapors. The Tester is made up of 2 parts: the reagent and the plastic bag. One part contains light yellow crystals that change color when exposed to alcohol vapors. The other part (plastic bag) collects the volume of air necessary for the analysis.
If alcohol is present, the crystals will change from yellow to light green. The number of crystals that change color will depend on the cut-off of the Tester and the amount of alcohol in the breath.
The yellow crystals in the reagent are coated with Chromium VI oxide (CrO3) and sulfuric acid (H2SO4). The amount of these indicator chemicals is adjusted according to the selected cut-off of the tester. A color change is produced when alcohol vapors are oxidized to acetic acid and the indicator chemicals change to chromium sulfate [Cr2(SO4)3]. The majority of crystals change from yellow to light green when alcohol vapors are present at a level equal to or exceeding the cut-off of the Tester. The Contralco Tester is available in several cut-offs (0.02, 0.04, 0.05, 0.06, 0.08 and 0.10%). The cut-off is printed on the Tester label and is expressed as a specific percentage of breath alcohol.

Summary of Performance Studies
A study was conducted to compare Contralco Alcohol Breath Tester with a quantitative comparator device. The purpose of the study was to determine if consumers could correctly perform and interpret the test according to the package insert. The quantitative comparator device is LION, manufactured by LION LABORATORIES LIMITED.
Multiple user studies were performed to establish that the user could read and understand the directions provided and properly use the device.
This study was conducted at the exit of a nightclub. Volunteers blew in balloons, and interpreted the results of the reactant. The volunteers then immediately provided another breath sample, which was analyzed using the quantitative device operated by a trained individual.
59 measures were taken.
The results from the Contralco Alcohol Breath Tester are coherent with the results of the quantitative comparator device (LION). Only one measurement is not coherent with the results of the quantitative comparator. In this case, the Contralco Alcohol Breath Tester is 98% effective.
