Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair retains a historical record of drug and alcohol use because biomarkers are deposited within the hair as it grows. Collected at the scalp, hair samples can reveal a detection period of up to three months for drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and simple to transport.
A hair sample of 1.5 inches containing around 200 strands (comparable to a #2 pencil) taken from the scalp area provides 100mg, which is optimal for screening and confirmation purposes. For EtG testing, additional tests, or panels exceeding 10, a sample of 150mg is advisable. We suggest using a jeweler's scale to weigh the specimen. If scalp hair is unavailable, a similar quantity of body hair can be obtained as a substitute. When referring to head hair, we mean scalp hair exclusively. Body hair includes all other types (such as facial and axillary hair).
Process Overview
The drug test results are processed through four main stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is logged into the laboratory's system. This involves checking that the sample is properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and entering additional data not captured via electronic chain of custody.
Screening provides an initial assessment for drugs of abuse. Though a budget-friendly way to exclude drug usage for most samples, positive screens must be confirmed for legal purposes. Samples indicating possible positive results in Screening require further verification.
In cases of presumed positive results during Screening, additional hair is taken from the original sample for Extraction. This stage extracts drugs from hair in much lower concentrations than other methodologies (such as urine or oral fluid), making hair drug screening the most challenging methodology.
Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with probable positive outcomes are washed as part of the confirmation process if needed. The entire process, from Accessioning to Confirmation, is conducted following CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
