The analysis of hair has become recognized as an effective method for identifying drug and alcohol consumption. Hair can encapsulate a long-term record of alcohol and drug presence by embedding biomarkers within the strands of its ongoing growth. When taken from near the scalp, hair can reveal up to a 90-day detection period for alcohol and drugs. Hair is easy to obtain, relatively hard to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (around the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional options, and/or tests exceeding 10 panels, a sample of 150mg is suggested. Using a jeweler's scale to measure the specimen is recommended. If scalp hair is not an option, a comparable quantity of body hair may be utilized. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary four stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab's system, which involves checking the sample's proper seal and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not available through an electronic chain-of-custody system.
Screening incorporates an initial rapid assessment for drugs of abuse. Although Screening is cost-efficient for ruling out drug usage in most samples, a positive result must be verified for legal admissibility. Samples indicating a presumptive positive in Screening require further confirmation.
If a sample indicates a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. During this phase, drugs are isolated from hair at a significantly lower concentration compared to other methodologies (e.g., urine or oral fluid), highlighting why hair drug screening is among the most challenging methodologies to conduct.
Verification of any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives are cleansed as necessary prior to confirmation. The whole lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
