Examining hair has become recognized as a potent method for detecting the usage of drugs and alcohol. Hair captures a lasting record of alcohol and other substances by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can show a detection window for alcohol and other drugs extending up to around three months. It is easy to collect, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp yields 100mg of hair, the preferred sample size for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair is not available, a comparable amount of body hair can be gathered. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initiating a sample's processing within a laboratory’s framework. This step ensures the sample's seal and shipping correctness, assigns a LAN (Laboratory Accessioning Number) randomly, and finalizes any extra data entry not provided electronically.
Screening includes a swift initial check for the presence of drugs. While Screening offers an economical means to exclude drug use in most samples, for courtroom admissibility, any positive result requires confirmation. Samples that are tentatively positive during Screening necessitate a secondary confirmation.
In cases where a sample shows tentative positivity during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted in hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), which is why hair drug testing presents the most challenging execution.
All positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with tentative positivity are cleansed as necessary. The full laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair specification alongside ISO/IEC 17025 standards accreditation.
