Hair assessments are recognized as a potent method for identifying substance use, including drugs and alcohol. Hair offers an extended timeline of alcohol and drug intake by embedding biomarkers within the hair strand’s fibers as it grows. When samples are taken from near the scalp, they can reveal alcohol and drug presence up to around a three-month window. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.
A hair sample measuring 1.5 inches with approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for analytical screening and verification. For EtG extensions and/or tests exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to weigh the sample using a jeweler's scale. In cases where scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair relates to all other types (e.g., facial, axillary).
Process Overview
The primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial step of entering a sample into the lab system, ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any residual data input absent from an electronic chain of custody method.
Screening involves an initial quick assessment for substance abuse. Though Screening is an economical method to exclude drug use for most samples, a positive result must be verified to be court-admissible. Samples that are tentatively positive in Screening demand a secondary confirmation.
If a sample shows a tentative positive result during Screening, additional hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted at considerably lower concentrations than with alternative methods (e.g., urine or oral fluid), explaining why hair drug screening is one of the most challenging methodologies to conduct.
Verification of any positive Screening outcome is executed through GC/MS, GC/MS/MS or LC/MS/MS. All samples that temporarily test positive undergo washing before confirmation, as needed. From Accessioning to Confirmation, the entire lab process falls under both the CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.
