Hair analysis has gained prominence as an effective method for identifying consumption of illicit substances and alcohol. Hair retains a comprehensive record of substance usage by embedding biomarkers within the strands of hair as it grows. By collecting hair proximal to the scalp, one can expect a detection duration of up to roughly three months for alcohol and drugs. Hair collection is straightforward, reasonably difficult to tamper with, and uncomplicated to transport.
A sample measuring 1.5 inches comprising approximately 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp can yield 100mg of hair, ideal for examining via screening and confirmation. For EtG, additional panels, or tests surpassing 10 panels, a specimen weighing 150mg is advisable. It is suggested to use a jeweler’s scale to weigh the sample. If scalp hair is not available, equivalent amounts of body hair can be used. When referencing head hair, this pertains solely to scalp hair. Body hair includes all alternative types (facial, axillary, etc.).
Process Workflow
The laboratory procedure for processing a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample processing into a lab's system. This consists of confirming proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any additional data entry omitted by an electronic chain of custody system.
Screening serves as a preliminary examination for abuse substances. Although Screening is an economical method to exclude drug usage for a majority of samples, confirmed results are necessary for legal admissibility. Samples testing positive in Screening necessitate secondary confirmation.
When a sample emerges presumptively positive during Screening, further hair is harvested from the original specimen for Extraction preparation. In Extraction, drug compounds are extracted from hair, reflecting a significantly lower concentration than alternative methods (e.g., urine or oral fluid), showcasing why hair drug testing is among the most challenging to execute.
Confirmation of any positive result identified during Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing prior to confirmation as required. The entire process, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair distinction and ISO/IEC 17025 accreditation standards.
