Hair testing is now acknowledged as a potent measure for identifying drug and alcohol consumption. Hair can document long-term use of alcohol and substances by embedding biomarkers within the fibers of the growing strand. When clipped near the scalp, it offers nearly a 3-month detection period for alcohol and other drugs. Hair is easy to obtain, relatively tough to tamper with, and simple to ship.
A snippet of approximately 1.5 inches from around 200 hair strands (about the size of a #2 pencil) closest to the scalp yields 100mg of hair, the perfect sample for screening and validation. For EtG, additions, and/or assessments beyond 10 panels, 150mg of hair is advised. We suggest measuring the sample using a jeweler's scale. If scalp hair is inaccessible, a similar quantity of body hair can be used. Whenever we talk about head hair, we're specifically referring to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
Four crucial steps are involved in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initializing a sample into a lab's system. This step ensures the sample was correctly sealed and dispatched, a random LAN (Laboratory Accessioning Number) is assigned, and any additional data entry not available through an electronic chain of custody system is completed.
Screening involves an initial rapid check for substances of abuse. Even though Screening is an economical technique to dismiss drug use in most samples, any positive screening outcome must be verified to be valid in court. Samples that are provisionally positive in Screening need a follow-up confirmation.
If a sample is provisionally positive during the Screening step, additional hair is taken from the original batch and readied for Extraction. Drugs are extracted from hair here at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), thus making hair drug screening the most challenging technique to perform.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as needed. The full lab process from Accessioning to Confirmation is checked under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO/IEC 17025 standards.
