Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. The hair captures biomarkers of alcohol and drugs within the fibers of its growing strand, offering a long-term record. When hair is gathered near the scalp, it can reveal a detection window of up to roughly 90 days for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
Collecting a 1.5-inch sample close to the scalp, consisting of roughly 200 strands of hair (akin to the width of a #2 pencil), results in 100mg of hair, the optimal quantity for testing and validation. For EtG, additional tests, and those exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler's scale for weighing the sample is suggested. If scalp hair isn't available, an equivalent amount of body hair may be used. Here, head hair refers exclusively to scalp hair. Body hair encompasses all other hairs (such as facial, axillary, etc.).
Process Overview
The primary steps in laboratory processing for a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is processed into a laboratory's system. This stage ensures the sample was correctly sealed and dispatched, generates a unique LAN (Laboratory Accessioning Number), and completes any additional data entry that might be missing from an electronic chain of custody system.
Screening serves as an initial examination for drugs of concern. While Screening offers an economical approach to excluding drug usage in most samples, a positive screen necessitates confirmation to be court-admissible. Samples that appear positive during Screening require a secondary confirmation.
If a sample tests positive presumptively in Screening, additional hair is extracted from the original sample and prepared for Extraction. At this step, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug analysis the most challenging methodology to execute.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed prior to confirmation as applicable. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair categorization and ISO / IEC 17025 accreditation standards.
