Hair examination is now regarded as a significant method for uncovering drug and alcohol consumption. Hair captures a comprehensive timeline of substances by embedding biomarkers within the strands as they grow. When hair is sampled near the scalp, it offers a detection period of up to around three months for drugs and alcohol. Collecting hair is straightforward, relatively resistant to tampering, and straightforward to transport.
A 1.5-inch section consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, add-ons, and/or assessments exceeding 10 panels, a specimen weight of 150mg is advised. It is suggested to use a jeweler’s scale to weigh the sample. If scalp hair cannot be collected, an equivalent volume of body hair is acceptable. Scalp hair specifically pertains to head hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial sample processing into the laboratory system. This includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not available through an electronic chain of custody system.
Screening performs an initial rapid check for drugs of abuse. Though Screening is an economical method to exclude drug use in most samples, any positive screens must be verified for legal admissibility. All samples indicating potential positive results in Screening necessitate a follow-up confirmation.
If Screening suggests a positive result, more hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are leached from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug analysis one of the most challenging methodologies.
Positive Screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are subjected to washing prior to confirmation when necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 accreditation.
