Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands trap biomarkers over time, offering insight into long-term usage when samples are taken near the scalp, allowing for up to a three-month detection period for substances. Collection is straightforward, tampering is challenging, and shipping is efficient.
To conduct the screening and confirmation, a 1.5-inch sample consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields about 100mg, which is optimal. An amount of 150mg is advised for EtG, additional panels, and tests exceeding 10 panels. Utilizing a jeweler's scale for precise weight measurement is advisable. In the absence of scalp hair, collecting an equivalent amount of body hair is permitted. "Head hair" strictly refers to scalp hair, while "body hair" encompasses other types (such as facial and axillary).
Process Overview
The laboratory processing leading to a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample incorporation into a lab's system, confirming seal integrity and proper shipping, randomly assigning a LAN (Laboratory Accessioning Number), and completing any data not provided electronically via a chain of custody.
Screening provides a preliminary check for drug presence. Though economical for ruling out drug usage in most cases, a positive screen mandates further confirmation for legal admissibility. Positively indicated samples in Screening necessitate secondary validation.
Should a sample show presumptive positivity at the Screening stage, additional hair is extracted from the initial sample for the Extraction process. Here, drug compounds are isolated at lower concentrations than with alternative methods (like urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmation of any preliminary positive findings is done using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Required pre-confirmation washing is applied to all presumptive positive samples. The entire lab process from Accessioning to Confirmation adheres to the standards set by CAP (College of American Pathologists) under the Hair designation and ISO / IEC 17025 accreditation.
