Hair examinations are now regarded as an effective means for uncovering drug and alcohol consumption. The fibers of a growing hair strand encase biomarkers, offering a prolonged record of alcohol and drug presence. When gathered from near the scalp, hair offers a detection span of up to about three months for alcohol and drugs. Hair is easy to collect, somewhat resistive to tampering, and straightforward to transport.
A sample size of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil's girth) nearest the scalp yields 100mg of hair—ideal for preliminary and confirmatory assessments. For EtG, extra tests, or those exceeding 10 panels, a 150mg specimen is suggested. It is advisable to use a jeweler's scale for specimen weighing. If scalp hair isn't accessible, a corresponding quantity of body hair can be used. Scalp hair exclusively refers to head hair, while body hair spans all other types (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This process confirms the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and finalizes any data entry absent from an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of misuse. Although screening is cost-effective for eliminating drug use from most samples, any positive result requires confirmation for court acceptance. Samples flagged as presumptively positive need further confirmation.
Should a sample show presumptive positivity at the Screening stage, additional hair is drawn from the original sample for Extraction. This stage extracts drugs from hair at much lower concentrations than seen in other techniques (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening finding uses GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The entire lab process, from Accessioning to Confirmation, undergoes review by both the CAP (College of American Pathologists) Hair designation and the accreditation under ISO / IEC 17025 standards.
