Hair analysis is now recognized as a potent method for detecting substances like drugs and alcohol. With the ability to preserve a historical record of substances by embedding biomarkers in the hair fibers, hair provides an extensive timeline of use. When gathered near the scalp, hair offers a detection period stretching to about three months for both alcohol and drugs. The collection process is straightforward, though tampering is challenging, and it is convenient for transport.
Securing a 1.5-inch section of around 200 hair strands (comparable to a #2 pencil thickness) nearest to the scalp yields 100mg of hair, which is ideal for evaluation and verification. For EtG, additional assessments, or tests exceeding 10 panels, it is advised to use 150mg of the sample. It's advisable to weigh the sample using a jeweler's scale. If head hair is inaccessible, a similar amount of body hair may be substituted. When discussing head hair, we mean solely scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of drug test outcomes consists of four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where the sample is integrated into the laboratory system. This step involves confirming the sample was appropriately sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody mechanism.
Screening provides an initial inspection for illicit substances. Although it is a cost-efficient procedure to eliminate drug presence in most samples, any positive screening must be verified for legal acceptance. Samples showing presumptive positives during Screening necessitate additional confirmation.
When a sample is assumed positive at the Screening phase, more hair is drawn from the primary specimen for the Extraction process. Here, substances are extracted from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), thus, hair drug screening is the most intricate method to conduct.
Confirmation of any positive screen is carried out utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing prior to confirmation as needed. The complete laboratory procedure, from Accessioning to Confirmation, is overseen following both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
