What Is the Difference Between ETG and ETS Testing?

ETG (Ethyl Glucuronide) and ETS (Ethyl Sulfate) are both metabolites produced when the body processes alcohol. Many laboratories measure both markers because together they can provide additional information regarding recent alcohol exposure.

What Is ETG?

ETG stands for Ethyl Glucuronide.

ETG is created when alcohol is metabolized by the body and remains detectable longer than alcohol itself.

What Is ETS?

ETS stands for Ethyl Sulfate.

Like ETG, ETS is also produced after alcohol consumption and may be measured during alcohol testing.

Why Laboratories Sometimes Measure Both

Testing for both ETG and ETS may:

  • Support result interpretation
  • Improve confidence in findings
  • Provide additional monitoring information
  • Help confirm alcohol exposure

Common Uses of ETG and ETS Testing

  • Family court monitoring
  • Child custody matters
  • Probation programs
  • Professional monitoring
  • Recovery programs
