Hair analysis is now recognized as an effective method for identifying alcohol and drug consumption. The hair strand, by embedding biomarkers within its fibers, offers an extended overview of alcohol and drug intake. When taken from the area near the scalp, hair can reveal a detection period of up to three months for alcohol and drugs. Hair is straightforward to obtain, hard to tamper, and simple to transport.
Collecting a 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, additional tests, and/or screenings beyond 10 panels, it is advisable to use a specimen of 150mg. It is advisable to weigh the sample using a jeweler's scale. If scalp hair is not available, the same quantity of body hair can be used. When mentioning head hair, we're specifically discussing scalp hair. Body hair refers to hair from other areas (facial, axillary, etc.).
Process Overview
The key stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary processing of a sample into the laboratory's system. This step ensures that the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and addresses any additional data entry missing from an electronic chain of custody system.
Screening performs an initial rapid check for drugs. Although Screening is an economical approach to exclude drug usage in most samples, positive findings must be confirmed to be accepted legally. Samples that are tentatively positive during Screening require subsequent confirmation.
For samples tentatively positive during Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are extracted from the hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug analysis is the most challenging method to execute.
Confirmation of any positive result from Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that are tentatively positive undergo washing before the confirmation process as needed. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.
