Hair analysis is increasingly recognized as an effective means of identifying drug and alcohol consumption. The continuous growth of hair strands encases biomarkers, offering an extended timeline for assessing drug use, usually up to around three months when the hair is sampled from near the scalp. This method is easy to collect, challenging to manipulate, and convenient to transport.
A 1.5-inch segment, approximately the thickness of a #2 pencil, of 200 hair strands nearest the scalp is optimal, yielding about 100mg of hair for testing purposes. For EtG add-ons or tests exceeding 10 panels, 150mg is the advised sample size. Utilizing a jeweler’s scale to weigh the sample is recommended. Should scalp hair be unavailable, a comparable amount of body hair can be collected. By head hair, we mean solely scalp hair; by body hair, we denote all other hair types (such as facial and axillary).
Process Overview
The key stages in lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is initially processed within the lab's framework. This step involves ensuring proper sealing and shipment of the sample, issuing a unique LAN (Laboratory Accessioning Number), and inputting any missing data not covered by an electronic chain of custody framework.
Screening provides a preliminary, rapid assessment for drug presence. Although cost-effective for identifying drug absence in most samples, any positive screening results must undergo verification for courtroom validity. Any samples that present a presumptive positive result during Screening require additional confirmation.
Given a presumptive positive during Screening, further hair is extracted from the original sample for the Extraction phase, where drugs are isolated from the hair, albeit at lower concentrations compared to other methods such as urine or oral fluid testing. Due to these complexities, hair drug screening ranks as a more complicated method.
Confirmation of positive screenings employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positives are cleansed as necessary before confirmation. This entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation protocols.
