Hair testing is perceived as an effective method for identifying drug and alcohol presence. The fibers of a hair strand in growth capture biomarkers, offering an extended timeline of alcohol and drug history. When taken close to the scalp, hair can reveal usage of alcohol and drugs up to roughly three months back. Hair is straightforward to gather, less prone to tampering, and convenient to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil diameter) from near the scalp provides 100mg, which is ideal for screening and confirmation. For EtG, additional panels, and tests exceeding 10 panels, 150mg is suggested. Utilizing a jeweler's scale for specimen weighing is advised. If scalp hair isn't available, an equal quantity of body hair might be collected. By head hair, we mean solely scalp hair. Conversely, body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase whereby a sample enters the laboratory system. It includes verifying the integrity and proper shipment of the sample, generating a LAN (Laboratory Accessioning Number) randomly, and finalizing any outstanding data entry absent from an electronic chain of custody system.
Screening serves as a preliminary examination for drug presence. While Screening is a budget-friendly approach to exclude drug use in most samples, a favorable screen requires a confirmation for court validity. Samples that test presumptive positive in Screening undergo further confirmation.
Presumptive positives in Screening necessitate additional hair extraction from the initial specimen for further Extraction. During this phase, drugs are isolated from the hair at a considerably lower concentration than alternative methods (like urine or oral fluid), illustrating why hair testing is among the most challenging methodologies.
Positive screening results are substantiated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens are cleaned before confirmation if necessary. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
