Hair analysis is now regarded as an effective method for detecting alcohol and drug use. Hair captures biomarkers within the fibers of the growing strand, providing a long-term history of substance use. When collected near the scalp, hair can offer a detection window of roughly 3 months for various substances. It is easy to collect, resistant to tampering, and convenient for shipping.
A 1.5-inch sample containing approximately 200 hair strands, about the thickness of a #2 pencil, closest to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. We recommend weighing the sample using a jeweler’s scale. If scalp hair is not obtainable, an equivalent amount of body hair can be used. 'Head hair' references scalp hair exclusively, whereas 'body hair' includes all other hair types, such as facial and axillary hair.
Process Overview
The drug test result processing in the lab involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory's system. This consists of verifying the integrity of the sample's seal and shipping, assigning a unique LAN (Laboratory Accessioning Number), and performing any extra data input omitted by an electronic chain of custody system.
Screening is a preliminary and swift evaluation for drug presence. It is an economical method to rule out drug use for most samples; however, a positive result here must be confirmed for legal admissibility. All samples deemed presumptively positive during Screening require a follow-up confirmation.
Upon a presumptive positive from Screening, additional hair is extracted from the original specimen for the Extraction stage. At this point, drugs are extracted at much lower concentrations compared to other tests (e.g., urine or oral fluid), making hair drug tests notably challenging to execute.
Any positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. As necessary, presumptive positive samples are washed before confirmation. The entirety of the laboratory process, from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 standards accreditation.
