Ets/Etg Testing

Ets/Etg Urine and Alcohol Testing

ARCpoint Labs of Columbia, SC offers EtS (Ethyl Sulphate) and EtG (Ethyl Glucuronide) urinalysis testing for judicial systems, attorneys and businesses. EtS urine and alcohol tests are preferable over other processes for alcohol screenings in that they record any alcohol usage for up to eighty hours after consumption.

Alcohol Testing Methods

The two most common methods to test for alcohol are breathalyzers and simple urine tests.These methods will detect alcohol if it has been recently consumed. There was previously no method available to ascertain if alcohol had been consumed 24 hours later because the body processes alcohol rapidly. The rate is one drink each hour.

ARCpoint Labs of Columbia, SC uses two newly developed techniques for testing. The EtS (Ethyl Sulphate) and EtG (Ethyl Glucuronide) tests are methods that sketch the entire history of alcohol consumption for the previous eighty hours. This tool is useful for zero-tolerance policies, concerns regarding workplace consumption and matters of family court.

How an EtG/EtS Urine Alcohol Test Works

Ethyl glucuronide (EtG) is a metabolite produced only when alcohol is present in the blood stream. An analytical process identifies the alcohol. This provides forensic evidence and documents any pattern of alcohol abuse or absence of abuse.

The more alcohol consumed by an individual, the higher the amount of EtG markers in the bloodstream. When EtG is present in the urine, recent alcohol consumption can be established. This is true after ethanol alcohol can no longer be measured. A urine alcohol test using EtG is more accurate to recent alcohol consumption than measuring for existing ethanol alcohol.

If EtG is detected by the laboratory in the sample of urine, another alcohol metabolite called EtS may also be tested. The reliability and accuracy of the test is improved when testing for these metabolites.
