Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive history of substance use by encapsulating biomarkers within the strands as they grow. When clipped close to the scalp, hair can reveal usage history for up to around three months for alcohol and drugs. Its collection is straightforward, tampering is relatively challenging, and it is simple to send off for testing.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the diameter of a #2 pencil) from nearest the scalp provides 100mg, which is an ideal amount for both screening and confirmation analyses. For EtG screenings, add-ons, and/or tests exceeding a 10-panel assessment, a 150mg sample is advisable. It's suggested to measure the sample's weight with a jeweler's scale. If scalp hair cannot be obtained, body hair of the same volume may be used. "Head hair" pertains exclusively to scalp hair; "body hair" includes all other types (facial, underarm, etc.).
Process Overview
The laboratory examination of a drug test sample mainly involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of integrating a sample into a lab's system initially. This step involves checking that the sample is appropriately sealed and transported, assigning it a LAN (Laboratory Accessioning Number), and performing any additional data entry not covered by an electronic chain of custody mechanism.
Screening serves as a preliminary, swift inspection for drugs. This determines basic drug presence, offering cost-effective preliminary information. Any screening that indicates a potential drug presence requires further verification to be used legally. Thus, samples shown as possibly positive must undergo secondary confirmation.
In instances where a sample evidences a presumptive positive from Screening, additional hair is taken from the original specimen for the Extraction phase. Here, substances are separated from hair at notably lower concentrations compared to alternative methods (e.g., urine or oral fluid), enhancing the complexity of hair drug screening.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, each sample noted as presumed positive undergoes a washing procedure if necessary. The complete process from Accessioning to Confirmation undergoes scrutiny as per both CAP (College of American Pathologists) Hair designation criteria and ISO / IEC 17025 standard accreditation.
