EtG alcohol test for a Fort Worth custody case
EtG is a urine test that can show recent alcohol ingestion after a standard breath test would be clear. We collect EtG at 601 University Dr, Suite 103, Fort Worth, and at the Dallas site. Bring the court order if the test is court-ordered. Results are lab-based. Call (682) 882-3784.
PEth
PEth is a blood or dried-blood-spot test used when the court or program wants a longer window than EtG. Collection is by appointment.
