Mild or moderate alcohol consumption the night before your test (1-2 drinks) shouldn’t have a major impact on the results.
However, excessive alcohol can lead to a variety of physiologic changes including reduced plasma volume, altered acid-base balance, and electrolyte changes that can make your Vessel results inaccurate. Because of this we don’t recommend testing if you have been drinking heavily.
