Hair analysis is now deemed an influential method for identifying drug and alcohol consumption. Hair captures a lengthy history of these substances by encapsulating biomarkers within the hair's elongating fibers. When cut near the scalp, it can reveal up to roughly a 3-month timeframe for detecting these substances. It’s straightforward to gather, resistant to tampering, and convenient to transport.
A 1.5-inch segment comprising about 200 hair strands (approximately the dimensions of a #2 pencil) nearest the scalp ensures 100mg of hair, the optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. It’s best to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair is an acceptable substitute. When discussing head hair, it exclusively pertains to scalp hair. Body hair refers to all other types (facial, axillary, etc.).
Process Overview
The primary four stages in laboratory drug test analysis include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a specimen into a lab’s system. This process ensures the sample’s proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fulfills any supplementary data entry absent from an electronic chain of custody system.
Screening serves as an initial assessment for drug presence. Although Screening is economical for eliminating drug detection in most samples, a positive result must be validated for legal admissibility. Samples preliminarily positive during Screening necessitate secondary confirmation.
If the Screening phase indicates a sample is preliminarily positive, more hair is extracted from the initial lot for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), justifying why hair testing is notably challenging.
Confirmation for any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating potential positivity undergo a cleansing before confirmation, as required. The complete laboratory procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 compliance standards.
