Seen as a robust instrument, hair testing effectively identifies drug and alcohol consumption. Hair offers a long-standing record of substance use by capturing biomarkers within the growth of the hair itself. When taken from near the scalp, hair samples can reveal substance use for up to three months. It's easy to collect hair, challenging to tamper with, and convenient to transport.
A sample sized at 1.5 inches of 200 hair strands (comparable to a #2 pencil's width) near the scalp is required to gather 100mg, the desired quantity for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, a 150mg sample is ideal. Using a jeweler’s scale for measurement is advised. Should scalp hair not be obtainable, a comparable quantity of body hair may be acquired. Only scalp hair is meant when referencing head hair. All other types of body hair (beard, underarm, etc.) fall under body hair.
Process Overview
The laboratory processing of a drug test result includes four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample initially undergoes processing within the lab's system. This ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and addresses any data entry gaps not handled by the electronic chain of custody.
Screening provides a preliminary analysis for substances. While cost-effective, a positive screen must undergo Confirmation to hold legal merit. Any presumptive positives in Screening necessitate further confirmation.
For samples testing positive in Screening, additional hair is retrieved from the initial amount and readied for Extraction. Drugs are then drawn from hair at notably low concentrations compared to other tests (e.g., urine or saliva), making hair drug screening complex.
Confirmation of positive screenings occurs using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are cleansed before confirmation if necessary. The complete lab workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
