Hair testing has been recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug ingestion by embedding biomarkers within the fibers of the developing hair shaft. When harvested near the scalp, hair can offer a detection period of up to around three months for both alcohol and drugs. Hair is easy to gather, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for evaluating and confirming. For EtG, supplementary assessments, and/or evaluations exceeding 10 panels, it is suggested that 150mg of the specimen be used. It is advised to measure the sample's weight using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be collected. In terms of head hair, this specifically means scalp hair. Body hair includes all other hair variations (facial, axillary, etc.).
Process Overview
The four fundamental stages involved in the lab processing of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of initially processing a sample into a lab's database. This encompasses confirming the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening comprises a preliminary swift examination for drugs of misuse. Even though Screening is a budget-friendly means to exclude drug usage for the majority of specimens, a positive result necessitates confirmation to be permissible in court. Any specimens that show a presumptive positive in Screening must undergo a subsequent confirmation.
If a specimen shows a presumptive positive in the Screening phase, more hair is taken from the initial sample and made ready for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than in other methodologies (e.g., urine or oral fluid), which is why hair drug screening ranks as the most challenging methodology to execute.
Any screening result that is positive is verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a cleansing before confirmation when necessary. The complete laboratory process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
