The utilization of hair testing is increasingly acknowledged as an effective method for detecting drug and alcohol consumption. Hair delivers a longitudinal overview by capturing biomarkers within the strands as they develop. When obtained near the scalp, hair offers an approximate detection period of up to three months for alcohol and drugs. The collection process is straightforward, tampering is relatively challenging, and shipping is convenient.
A hair sample measuring 1.5 inches, with around 200 strands (similar in thickness to a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal quantity for analysis and validation. For EtG tests, add-ons, or when exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to ascertain the specimen's weight using a jeweler’s scale. If scalp hair is absent, equivalent body hair may be utilized. When discussing head hair, it pertains solely to scalp hair. Body hair pertains to all other types (e.g., facial, axillary).
Process Overview
There are four principal steps in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is processed into the lab's system. It includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any missing details absent from an electronic chain of custody.
Screening serves as a preliminary assessment for drug abuse. Screening is economical for excluding drug use in most samples, yet a positive outcome necessitates confirmation for legal admissibility. Samples presumed positive during Screening require further confirmation.
For samples presumed positive in the Screening phase, additional hair is extracted from the original sample for Extraction. Here, drugs are extracted from hair at much lower concentrations compared to other methodologies (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of positive screening results is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
