EtG testing is a means to detect exposure to ethanal alcohol.
The presence of EtG does not indicate that a person is presently intoxicated, but that
they have been exposed to ethanal alcohol usually through consumption. EtG testing is detecting
a bio-marker that is a byproduct of the liver produced after the body has metabolized alcohol.
EtG testing cannot determine how much or when a person consumed alcohol, only that alcohol was consumed.
EtG is usually tested within three different thresholds: 100/200/500 ng/mL. The most commonly used test by
probation officers is the 500 ng/mL threshold to avoid false positives. A positive test above the 500 ng/mL threshold
is considered reliable results by most courts in determining a violation.
If you have done an internet search for this same topic it is likely that you came across numerous pages that boast EtG as the 80 hour
test. EtG tests will only detect consumption of alcohol up to 80 hours in the most extreme cases, EtG tests will in reality detect ethanal alcohol
exposure 5-48 hours post drinking. I have created a simple calculator / estimating tool below to give an example of how long exposure can be detected
in reality based upon scientific research I have found.
EtG levels present in urine indicates the consumption of alcohol recently, it does not validate current impairment or
drunkenness. To measure current impairment or drunkenness a blood alcohol test would need to be administered or a breathalyzer.
EtG tests should not be used post-accident or in employment screening, but EtG tests are an effective tool to detect daily drinkers
and/or non-compliance with abstinence orders. Notably EtG tests are commonly administered post mortem to determine if any substances
were a contributing factor in death.

When using the EtG Calculator consider this chart to measure one drink. Keep in mind that drinks served at a bar,
especially cocktails may contain more alcohol than what is expressed here. For example many drinks contain mixers
and more than one shot of multiple types of liquors. 80 proof = 40% alcohol. When reading proof on a bottle divide
that number by two. That is the percent of alcohol the drink contains.
Check out the link below to find out how much alcohol a drink contains.
This calculator will estimate based on a persons average age of 33 years old, male, with
an average weight of about 178 lbs. The data used to formulate this test included persons aged
21-60, both male and female, and 122-239 lbs. If you suffer from kidney or liver disease this test
will not yield accurate results. Taking certain medications may also yield false results.
Your Estimated Peak EtG Level Was:
Your Estimated BAC Was:
It will take about hours from the time you stopped drinking for your
EtG urine level to be under 500. Please remember exact EtG levels can only be calculated by
a labatory test. This is just an estimate that seems to be reasonably reliable.
For levels lower than 500: EtG = 250 add 3 hours, EtG = 125 add 6 hours, EtG = 75 add 9 hours...

Does drinking water decrease my EtG levels?
Studies have indicated that drinking significant amounts of water will decrease
your EtG levels in urine temporarily however, how much is unknown. After drinking it is never a bad idea to flush if you need
to, drink only water and eat normally. Your urine should appear mostly clear, dark urine indicates dehydration and you need to
drink water anyway. If your tester uses a laboratory however, they may measure EtG against the creatine levels in your urine, in this case
the result will be the same. Also beware of testers accusing you of diluting due to the fact that your urine is a little too clear. Take
a multivitamin 3 hours prior to testing and that should add some color.
A sample can be diluted by drinking 1-2 liters (minimum) of water prior to testing. It is recommended that you urinate several times
while continuing to drink water prior to testing. When your urine is clear keep drinking water and test. This is how a test is diluted
and EtG testing will likely not return a positive result. However this should be a last resort to save yourself.
Will Drinking Bleach Help Me Pass A Drug / Alcohol Test?
No, do not do this!Drinking a small amount of bleach won't kill you, particularly if you dilute it in water, but it is
corrosive and can irritate or damage your mucous membranes and esophagus. Ingesting a few milliliters of bleach most likely will
irritate your eyes, nose and throat and may cause nausea and vomiting and possibly diarrhea. Vomiting a small amount of bleach
is not recommended, since this re-exposes your esophagus to the chemicals and may worsen the damage. Drinking a larger volume
of bleach and ingestion of sodium (hypernatremia). Chest pain, low blood pressure, shock and possibly coma or death may result
from either inhaling too much bleach or drinking it.
Household bleach consists of about 5.25% sodium hypochlorite in water. Specifically, Clorox says their bleach contains water,
sodium hypochlorite, sodium chloride, sodium carbonate, sodium hydroxide and sodium polycrylate. They also make scented products
that include fragrances. Bleach also contains small amounts of impurities, which aren't a big deal when you're using the product
for disinfection or cleaning, but could prove toxic if ingested. None of these ingredients binds to drugs or their metabolites or inactivates them such
that you would test negative on a drug test.
Reading user submitted posts that swear by the use of bleach to beat a drug test there seems to be one commonality, they all
recommend drinking large amounts of fluid or water before consuming bleach. Essentially diluting the test. Therefore, it is
reasonable to assume that bleach is not the cause of the negative test and that dilution is. I added this to the site after
seeing several articles of dumb ass's drinking bleach, don't do this! You will be doing more harm to your body than good
and will NOT achieve the results your are looking for.
