Hair testing is now recognized as an effective instrument for detecting drug and alcohol consumption. Hair captures long-term records of alcohol and drug use by embedding biomarkers within the fibers of the strand. When taken near the scalp, hair offers an approximately 3-month detection window for alcohol and substances. Collection is straightforward, tampering is not easy, and shipment is convenient.
A 1.5-inch lock of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp gives 100mg of hair, which is the ideal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to weigh the sample on a jeweler’s scale. If scalp hair is not accessible, an equivalent weight of body hair can be taken. Reference to head hair implies scalp hair exclusively. Body hair signifies any other type (facial, axillary, etc.).
Process Overview
The four primary stages in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initial handling of a sample into the laboratory's system. This process checks that the sample was sealed and shipped correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any data entry not done by an electronic chain of custody system.
Screening performs a swift preliminary test for drugs of abuse. Although Screening is economical for eliminating drug use in most samples, positive screenings must be confirmed to be valid in court. Samples that are presumptively positive during Screening require further confirmation.
For samples presumptively positive in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at a much lower concentration than other methodologies (like urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation for any positive screening result is conducted via GC/MS, GC/MS/MS or LC/MS/MS. Every presumptive positive sample is washed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation criteria.
