Recognized as an effective means for identifying drug and alcohol consumption, hair testing captures long-term biomarkers within its fibers as the hair strand develops. When harvested near the scalp, hair is capable of identifying alcohol and drug presence up to roughly a quarter-year period. The collection process for hair is straightforward, not easily compromised, and facilitates simple transport.
A portion of hair measuring 1.5 inches and comprising roughly 200 strands (comparable to a #2 pencil's width) that is located nearest the scalp equates to 100mg, the optimal quantity for both screening and verification. For EtG additions and/or tests exceeding 10 panels, a 150mg sample is preferred. We advocate for the sample to be weighed using a jeweler's scale. If scalp hair cannot be obtained, the equivalent quantity of body hair is an option. When mentioning head hair, we are specifically indicating scalp hair. Body hair encompasses all remaining hair types (facial, axillary, etc.).
Process Overview
The principal phases in the laboratory processing of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's workflows. This process includes the validation of proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any pending data input absent from an electronic custody chain system.
Screening provides a preliminary rapid assessment for drugs of abuse. Although Screening is an economical strategy to negate drug use in most samples, a positive result must be validated to be permissible in judicial proceedings. Any samples flagged as potentially positive during Screening mandate a secondary verification.
Should a sample appear positive during the Screening process, additional hair is retrieved from the original specimen and readied for Extraction, where drugs are extracted at notably lower concentrations than in alternative techniques (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screenings.
Confirmatory analysis for any positive screening outcomes is executed using GC/MS, GC/MS/MS or LC/MS/MS methodologies. All samples marked as presumptively positive undergo washing ahead of confirmation as dictated. The entire laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair specifications and certification to ISO / IEC 17025 standards.
