Hair testing is recognized as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of a hair strand as it grows, hair offers a comprehensive history of substance use. When samples are taken near the scalp, they can reveal drug and alcohol usage for up to about three months. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.
A 1.5-inch segment comprising roughly 200 hairs (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional tests, or screenings over 10 panels, it is advised to collect 150mg of the sample. Using a jeweler's scale for weighing the specimen is suggested. In instances where scalp hair is not available, an equivalent amount of body hair can be used instead. When mentioning head hair, it specifically refers to scalp hair. Conversely, body hair includes other types of hair (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's database. This phase confirms proper sealing and shipment of the sample, allocates a unique LAN (Laboratory Accessioning Number), and fulfills any supplementary data requirements absent from an electronic chain of custody process.
Screening provides an initial rapid evaluation for substances of abuse. While Screening serves as a budget-friendly method to exclude drug usage for the majority of cases, a positive screen must be validated for legal considerations. Samples that yield a preliminary positive in Screening necessitate further confirmation.
Should the Screening step indicate a presumptive positive, additional hair is extracted from the original sample and prepared for Extraction. This phase involves obtaining drugs from hair at a significantly reduced concentration compared to other methodologies (such as urine or oral fluid), which underscores the complexity of performing hair drug screening.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positivism undergo washing prior to confirmation when necessary. The entire laboratory procedure, spanning from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
