Patent ID: 8530177

Claim:
A method of detecting and/or quantifying trichloroethanol glucuronide (TCG) in an individual or a solution, the method comprising contacting an in vitro sample taken from the individual or a solution with a conjugate and an antibody that specifically binds to TCG, wherein said antibody generated against an immunogen of the structure where n=0 or 1; and where, when n=1, the crosslinker joins the carbonyl substituent of the tetrahydropyran ring to an antigenicity conferring carrier material (accm), and said antibody has less than 0.69% cross-reactivity to chloral hydrate, trichloroacetic acid and ethyl glucuronide as compared to reactivity of TCG, detecting the bound conjugate, and deducing from a calibrator value or calibrator values the presence or amount of TCG.
