Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged profile of substance use, encapsulating biomarkers within the hair shaft as it grows. Collected strands near the scalp can reveal an alcohol and drug detection period extending up to approximately three months. The collection process is straightforward, with minimal risk of tampering, and shipment is convenient.
Acquiring about a 1.5-inch sample of roughly 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for analysis and verification. For EtG, additional substances, and tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler's scale for weighing the specimen is advised. Should scalp hair be inaccessible, a comparable amount of body hair may be gathered. When specifying head hair, we refer exclusively to scalp hair. Conversely, body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample integration into a laboratory system, confirming proper sample sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any missing data entry not supplied by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drug abuse indications. Although Screening is an economical method to dismiss drug presence in most samples, confirming a positive result is necessary for legal admittance. Positive indications during Screening necessitate subsequent validation.
When a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drug residues are isolated from hair at relatively lower concentrations compared to other methodologies (e.g., urine or oral fluid), illustrating why hair drug testing is the most intricate method to execute.
Positive results from Screening are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before validation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes examination under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
