Hair testing is now perceived as a potent means of identifying drug and alcohol usage. Hair locks in biomarkers within the strands of hair in growth, offering a prolonged record of alcohol and drug consumption. When gathered directly at the scalp, hair can reveal drug and alcohol usage up to roughly a three-month period. Collection is straightforward, tampering is tricky, and shipping is convenient.
A sample of 1.5 inches containing approximately 200 strands, comparable to the size of a #2 pencil, cut near the scalp, yields around 100mg of hair, making it an optimal sample for screening and confirmation. For EtG, supplementary tests, or tests beyond 10 panels, a sample of 150mg is advisable. It's good practice to weigh the sample on a jeweler’s scale. When scalp hair is not present, a similar quantity of body hair might be used. In our context, head hair strictly refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
There are four core phases in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first handling of a sample within a laboratory setup. It entails ensuring the sample is sealed and shipped correctly, assigning it a random LAN (Laboratory Accessioning Number), and processing any supplementary data entry absent in the electronic chain of custody system.
Screening provides a preliminary assessment for substances of abuse. While it's a cost-efficient method to exclude drug usage for most samples, any positive screen obligates confirmation for court validity. Samples marked presumptive positive in Screening require further confirmation.
Should a sample be presumptive positive in the Screening phase, additional hair is retrieved from the initial sample for Extraction. In Extraction, drugs are isolated from hair at notably lower concentrations than other methodologies (such as urine or oral fluid), contributing to the complexity of performing hair drug screening.
Confirmation of a positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as required. The entire lab processing, from Accessioning to Confirmation, is validated under the CAP (College of American Pathologists) Hair designation and complies with the ISO / IEC 17025 accreditation.
