Hair analysis is recognized as a highly effective method for identifying drug and alcohol consumption. It offers an extended overview of substance use by capturing biomarkers within the strands. When collected near the scalp, hair samples can reveal up to a 3-month period of drug and alcohol use. The collection process is straightforward, reducing the likelihood of tampering and simplifying shipping.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) is sufficient for analysis, providing 100mg of hair, which is optimal for both screening and confirmation tests. For EtG tests, additional panels beyond 10, or add-ons, it is advised to gather 150mg. We suggest using a jeweler’s scale to verify specimen weight. If scalp hair is not available, a comparable volume of body hair may be used. The term "head hair" refers exclusively to scalp hair, while "body hair" encompasses other types (such as facial or axillary).
Process Overview
The laboratory processing to determine drug test results encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample's entry into the lab system is handled, including ensuring correct sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any necessary additional data that is missing from an electronic chain of custody.
Screening provides a preliminary assessment for drug presence. Although it is a cost-efficient method for most samples, a positive screening outcome necessitates further confirmation to be legally acceptable. Samples flagged as positive in Screening undergo secondary verification.
If Screening yields a presumptive positive, additional hair is extracted from the sample for the Extraction step. This phase isolates drugs from hair at a considerably diluted concentration compared to techniques like urine or oral fluid analysis, underscoring the complexity of performing hair drug testing.
Positive Screening results are confirmed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, samples marked presumptive positive undergo required cleaning. Every step from Accessioning through Confirmation is conducted in compliance with CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.
