Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair archives a prolonged record of alcohol and drug presence by capturing biomarkers within the strands as they grow. When obtained close to the scalp, hair can reveal drug and alcohol use up to nearly a 3-month period. Hair collection is straightforward, challenging to tamper with, and uncomplicated to send.
A sample measuring 1.5 inches with roughly 200 strands of hair (about the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is the optimal quantity for screening and verification. For EtG, additional testing, and/or panels beyond 10, 150mg of the sample is advised. We suggest weighing the sample using a jeweler's scale. If scalp hair is not available, an equivalent quantity of body hair can be gathered. Our reference to head hair specifically denotes scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial preparation of a sample for entry into a laboratory’s framework. This process includes confirming that the sample was correctly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary swift evaluation for substances of abuse. Although screening is an economical means to dismiss drug use in most samples, a positive screen requires confirmation for legal admissibility. Any samples that yield a presumptive positive during screening demand further verification.
Should a sample yield a presumptive positive result during Screening, additional hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are isolated from hair at a much lower concentration than other methods (ex. urine or oral fluid), making hair drug analysis the most complex methodology to execute.
Confirming any positive results from screening occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
