ETG Hair Test Vs Urine Test Accuracy
Written By admin on
I might need to order an ETG hair test. My ex-wife is filing for full custody for our two children. Somehow, she has passed every urine alcohol test. We are unclear how she passes every test as she is a known alcoholic. My mother suggested trying an ETG hair test instead of a urine. She believes that a hair test will be more accurate than urine. Is this true? Will an ETG hair test return positive if the urine test

Hi John,
Your mother’s suggestion of the ETG hair
test is definitely on the right track if you want a better indicator of your ex-wife’s drinking habits. Ethyl glucuronide (EtG) is a strong marker for consumption of alcohol, but other alcohol tests, such as the urine ETG test, have a much shorter detection time. Keratinized tissues (hair, nail etc.) can retain foreign substances and thereby provide a longer detection time than standard urine drug screening or blood drug tests. While detection times for the urine ETG test are typically only a couple hours or days after consumption, the ETG hair test can detect alcohol months after consumption. In order for the ETG hair test to be performed the donor must have at least two inches of head hair. Donors are currently unable to use body hair this test. The standard ETG hair test has an estimated 90 day detection period. This is a relatively new test and therefore it is not cheap, but most of our clients find our pricing to be better than other drug testing agencies in Houston.
Another factor to consider is your ex-wife might be passing the urine tests because she is submitting someone else’s urine. If that is the case, the ETG hair test will eliminate that possibility. A person cannot go in to the lab and submit someone else’s hair. It is taken directly from the donor’s head.
