Immunoassay reagents intended to perform qualitative and/or quantitative analyses on a body fluid sample (e.g., serum, plasma, urine) to determine ethanol, the most often used and abused chemical substance. Immunoassay reagents used to determine ethanol may have some interference from other alcohols, particularly from isopropanol, methanol, and ethylene glycol. Reagents used to determine ethanol concentration in blood can establish the degree of alcohol intoxication, frequently as legal supporting evidence. Inclusion of additional tests for other alcohols such as methanol, isopropanol, and acetone as a metabolite of isopropanol are sometimes needed for evaluation of intoxicated patients.
