Hair testing is increasingly recognized as an effective means for detecting drug and alcohol use. Hair captures a long-term record of substances by embedding biomarkers within the strands during hair growth. A sample taken near the scalp can reveal usage over an approximately 90-day period for both alcohol and drugs. Collecting hair samples is straightforward, somewhat resistant to tampering, and easy to mail.
A 1.5-inch segment containing roughly 200 strands (comparable in size to a #2 pencil) close to the scalp yields 100mg of hair, which is the ideal quantity for both screening and verification. For EtG analysis, additional options, or tests beyond ten panels, 150mg of hair is advised. Utilizing a jeweler’s scale is recommended to measure the sample. Should scalp hair be unavailable, equivalent body hair can be used. "Head hair" refers solely to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Process Overview
Laboratory processing of drug test results is comprehensive, involving four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the integration of a sample into the laboratory's system. This includes the proper sealing and shipping verification, allocation of a random LAN (Laboratory Accessioning Number), and completion of any supplementary data entry that is missing from an electronic chain of custody system.
Screening provides a preliminary rapid assessment for the presence of drugs. Although Screening is a cost-efficient method to exclude drug usage in most samples, a positive screen mandates confirmation for legal admissibility. Presumptive positive samples in Screening necessitate secondary confirmation.
Samples with presumptive positive results in Screening proceed to Extraction, where additional hair is utilized from the initial sample. During Extraction, drugs are isolated from hair at concentrations notably lower than those in alternative matrices (e.g., urine or oral fluid), accounting for the complexity of hair drug screening.
Confirmation of a positive screening is achieved through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Positive samples are washed before confirmation as necessary. The full laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
