Recognized as an effective means for detecting drug and alcohol consumption, hair testing captures a lengthy history of substance use by embedding biomarkers within the fibers of the hair as it grows. If collected near the scalp, hair offers a detection timeframe of about 3 months for alcohol and other substances. Hair is easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch portion consisting of roughly 200 hairs (the approximate width of a #2 pencil) nearest the scalp provides 100mg of hair, the perfect sample for testing and verification. For EtG, additional tests, or analyses above 10 panels, 150mg of the specimen is advisable. It's best to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair can be collected. Referring to head hair indicates scalp hair exclusively. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample for the lab’s system. It involves confirming the sample's proper sealing and shipment, designating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.
Screening involves an initial swift assessment for drugs of abuse. Although Screening is an economical approach to exclude drug use for most samples, a positive screen must be confirmed for court admissibility. Samples presumptively positive in Screening necessitate a secondary confirmation.
For samples that test presumptively positive in Screening, further hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), underscoring why hair drug testing is the most challenging technique to execute.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
