Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by preserving biomarkers within the fibers of the developing hair strand. Collected near the scalp, hair can reveal a detection period of up to about three months for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) taken nearest to the scalp, will yield 100mg of hair, which is the preferred sample amount for evaluation and validation. For EtG, supplemental analyses, and examinations exceeding 10 panels, a 150mg specimen is suggested. Utilizing a jeweler’s scale for specimen weight is advisable. In the absence of scalp hair, a similar quantity of body hair can be gathered. Head hair pertains solely to scalp hair. Body hair includes all other forms of hair (like facial or underarm).
Process Overview
The laboratory processing for a drug test result encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial phase of sample integration into a laboratory’s infrastructure. This step involves ensuring the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and performing any supplementary data entry absent from an e-chain of custody framework.
Screening constitutes a preliminary rapid assessment for substance misuse. While it is a cost-efficient method to eliminate drug use in most samples, a positive Screening outcome necessitates confirmation for legal admissibility. Any samples that yield a presumptive positive in Screening mandate further confirmation.
If a presumptive positive arises in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are isolated from hair at lower concentrations than with other techniques (such as urine or saliva testing), which accounts for the complexity of hair drug screening.
Confirmation of any positive Screenings is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo pre-confirmation washing, as necessary. The complete laboratory protocol, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
