PEth / Phosphatidylethanol Blood Test

Detects alcohol use over the past 2–4 weeks — the gold standard for sobriety monitoring

The PEth (Phosphatidylethanol) blood test is the most accurate method for documenting long-term alcohol use or abstinence. Unlike breathalyzers or urine ETG tests that only detect recent drinking, PEth detects alcohol consumption going back 2 to 4 weeks from a single blood draw. It is widely used in custody cases, probation monitoring, HIMS pilot programs, and professional licensing compliance. No doctor referral required. Serving Schaumburg, Arlington Heights, Palatine, Naperville, Hoffman Estates, and surrounding Chicagoland suburbs.
