Accuracy of Consumer-marketed smartphone-paired alcohol breath testing devices: A laboratory validation study.

ABSTRACT:

Background

Although alcohol breath testing devices that pair with smartphones are promoted for the prevention of alcohol-impaired driving, their accuracy has not been established.

Methods

In a within-subjects laboratory study, we administered weight-based doses of ethanol to two groups of 10 healthy, moderate drinkers aiming to achieve a target peak blood alcohol concentration (BAC) of 0.10%.

Ten participants tested the first 3 devices, and the other 10 participants tested the ot
