The Exploro breast milk alcohol test strips are designed only for human breast milk, therefore, avoid dipping test strips directly into any alcohol drink because it will not show reliable results due to high sensitivity of the test strip. The test may be qualitatively verified by using a test solution prepared by adding 5 drops of distilled spirits to 8 oz. (1 cup) of water. This solution should produce a color reaction on the pad. The color reaction with alcohol in breast milk is somewhat slower and less intense than with alcohol in a water solution.
