Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair offers an extended timeline of substance usage by embedding biomarkers in the strands of growing hair. When hair is taken near the scalp, it can reveal up to around a 3-month period of drug and alcohol presence. The hair collection process is straightforward, making it less susceptible to tampering and easy to transport.
A sample measuring 1.5 inches from about 200 strands of hair (about as thick as a #2 pencil) next to the scalp yields 100mg, which is the recommended quantity for screening and verification. For EtG, additions, and/or tests exceeding 10 panels, 150mg is suggested. Utilizing a jeweler's scale for specimen measurement is advised. If scalp hair isn't present, an equivalent body hair sample should be taken. The term head hair exclusively denotes scalp hair, while body hair encompasses all other variations (facial, axillary, etc.).
Process Overview
The core stages in processing drug test results in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary registration of a sample within a lab's framework. It confirms secure shipping and sealing of the sample, allots a random LAN (Laboratory Accessioning Number), and handles any supplementary data input absent in an electronic custody documentation system.
Screening provides an expedient assessment for drugs. Despite Screening being a cost-efficient approach to detect drug usage in most samples, a positive outcome necessitates substantiation for judicial acceptability. Any samples indicating a presumptive positive in Screening need follow-up confirmation.
Presumptive positive samples from the Screening phase then have additional hair taken from the initial sample for Extraction. At this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which indicates why hair-based drug testing is particularly challenging.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed in accordance with both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 criteria.
