How much alcohol is 30 pg/mg of wine. How long does it take before you can pass a hair follicle test? As a result, cut-offs must be determined carefully. Logical as this may seem it has not been my experience, as I have seen many morning hour positive Soberlink tests that suggest a drinking episode the night before.

At DNA Legal, the length and location or hair sample obtained are given extended consideration when all expert analysis is drafted. While previous studies of EtG levels have shown ability to detect heavy drinking, Stewart and colleagues say that the more modest alcohol consumption detected in their study could exacerbate liver disease in susceptible individuals.
EtG can be detected by our assay system at levels even below 100 ng/ml, but we build in a "margin of safety" so that at 100 ng/ml we are very certain that EtG is present, indicating even small amounts of drinking. 1007/s00216-009-2863-0.
