The purpose of this study is to evaluate if the UpSpring Milkscreen Alcohol Test works to detect alcohol in breast milk that will be donated during this study. This research is being done because the sponsoring company, UpSpring, wants to determine if this test will work and, if it does, how well it will work to detect levels of alcohol in breast milk.

MilkScreen™ Home Test for Alcohol in Breast Milk is intended as an OTC test for the presence of alcohol in breast milk. This study will obtain data to demonstrate the agreement of MilkScreen™ compared to the reference method, head space Gas Chromatography-Mass Spectrometry (GC-MS) for alcohol content and will additionally provide validation of the usability of the device by the intended users.

The study will use a minimum of 50 lactating mothers who will come into a center in small groups in a contrived social setting like a wine tasting. Upon completion of informed consent and demonstration of meeting inclusion/exclusion criteria, subjects will be tested with disposable breathalyzer test and baseline breast milk samples provided. The baseline breast milk samples will be tested with the test article by the subject. Aliquots from the same samples will be prepared for testing by an outside lab with GC-MS.

Subjects will be asked to provide baseline demographics such as height and weight, days since birth of child, race/ethnicity, and information about any prescription or OTC drugs, herbal compounds or vitamins they have taken in the previous 72 hours.

Subjects will be provided with up to 3 alcoholic beverages over the course of a three to four hour period. At prescribed time intervals following consumption, subjects will be asked to provide a breast milk sample and to submit to a breathalyzer test. Each breast milk sample will be tested by the subject with the test article following the labeling instructions only and the sample will also be aliquoted into tightly sealing, low head space sample containers for method comparison testing by an outside lab with GC-MS.

Subjects will be asked to drink at least one drink, but may ingest up to two additional alcoholic beverages during the course of the study. Each subject's blood alcohol content (BAC) will be monitored before each additional drink is provided and will not be allowed to consume additional drinks if their BAC as measured by the disposable breathalyzer device exceeds 0.10% (100 mg/dL). All drinks will be prepared such that they contain alcohol consistent with a standard alcoholic drink, as defined by the National Institute on Alcohol Abuse and Alcoholism (12 ounces of beer, 8-9 ounces of malt liquor, 5 ounces of table wine, or 1.5 ounces of liquor). Subjects will be asked to self report whether they finished their drink at the point when samples are taken. Subjects will be provided with transportation to and from the study site using designated non-drinking drivers.

Samples of breast milk taken both prior to and following the ingestion of alcohol will be coded and thereby blinded to the lab. The lab will run GC-MS on each specimen and will report the results to the Sponsor. This data will be compared with the data reported by each subject and analyzed to demonstrate that the MilkScreen™ Home Test for Alcohol in Breast Milk agrees to a high degree to the reference method, GC-MS, to support the test article's intended use.

Subjects will be asked to complete a questionnaire on the usability of the labeling instructions on MilkScreen™ Home Test for Alcohol in Breast Milk to demonstrate that consumers can use the directions properly to test their breast milk for the presence of alcohol and properly interpret the results.
