The CDIATM Ethyl Glucuronide Colloidal Gold Test Cassette (Urine) is a lateral flow chromatographic immunoassay for the detection of ethyl glucuronide and its metabolites in human urine.
Ethyl Glucuronide antigen is coated on the test region of the nitrocellulose membrane of the strips, and ethyl glucuronide antibody is labeled with colloid gold. During a test, the colloid gold labeled antibody coated in the strip move forward along the membrane, and a red line will show up when the antibody gathers with the antigen in the test line; if ethyl glucuronide in the sample is over the detection limit, line T is blank; on the other wise, if ethyl glucuronide in the sample is less than the detection limit, line T is red.
Ethyl glucuronide (EtG) is a metabolite of ethanol which is formed in the body by glucuronidation following exposure to ethanol, usually from drinking alcoholic beverages. It is used as a biomarker to test for ethanol use and to monitor alcohol abstinence in situations where drinking is prohibited, such as by the military, in alcohol treatment programs, in professional monitoring programs (health professionals, attorneys, airline pilots in recovery from addictions), in schools, liver transplant clinics, or in recovering alcoholic patients. The CDIATM Ethyl Glucuronide Colloidal Gold Test Cassette (Urine) is a rapid urine-screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of EtG in urine. The CDIATM Ethyl Glucuronide Colloidal Gold Test Cassette (Urine) yields a positive result when the EtG in urine exceeds 500/300 ng/mL.
