Hair testing has evolved into a key method for identifying drug and alcohol consumption. It offers an extended historical record of substance use by capturing biomarkers within the fibers of hair as it grows. Hair samples taken near the scalp can reveal alcohol and drug use within a timeline of up to roughly three months. This method benefits from ease of collection, resistance to tampering, and straightforward shipping.
A sample consisting of 1.5 inches of approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp can yield 100mg of hair, the optimal sample mass for initial testing and verification. For tests focusing on EtG or exceeding 10 panels, a specimen of 150mg is advisable. Using a jeweler’s scale for measurement is recommended. In cases where scalp hair is unavailable, body hair may serve as an equivalent alternative. Mentioning head hair implies only scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
Laboratory drug test processing encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample enters a lab system, ensuring correct sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and completing data entry not covered by an electronic chain of custody.
Screening provides a swift preliminary examination of drug presence. Although cost-effective, positive screening outcomes require further confirmation for legal admissibility. Presumptive positive samples identified during Screening necessitate an additional confirmation process.
For samples deemed presumptively positive during Screening, additional hair is collected from the original sample for the Extraction phase. Here, drugs are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed before confirmation if necessary. The entire process, from Accessioning to Confirmation, is evaluated based on the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
