Hair analysis is increasingly recognized as an effective means for uncovering drug and alcohol consumption. Hair captures a history of alcohol and drug use by embedding biomarkers within the hair's fibers as it grows. If collected near the scalp, hair can indicate use over nearly a three-month period for alcohol and drugs. Hair is easy to gather, not easily tampered with, and convenient to transport.
A hair sample measuring 1.5 inches containing around 200 strands (approximately the diameter of a #2 pencil) nearest to the scalp delivers 100mg of hair, considered the optimal amount for analysis. When testing for EtG, additional analytes, or panels exceeding ten, a 150mg specimen is advisable. Utilizing a jeweler’s scale to measure the sample is recommended. If scalp hair is not available, the collection of a similar quantity of body hair is an option. It should be noted that head hair refers specifically to scalp hair. Body hair includes all other hair such as facial and axillary.
Process Overview
The primary laboratory steps in drug test analysis encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase where a sample is integrated into the lab's system. This step involves checking that the sample's seal and shipping were intact, issuing a unique LAN (Laboratory Accessioning Number), and completing any necessary manual data entry not captured by an electronic chain of custody.
Screening is a preliminary examination for drug presence. Although Screening is a cost-efficient approach to exclude drug use for many samples, a positive Screen result must be validated to ensure legal admissibility. Samples that test presumptively positive need further confirmation.
For samples that are presumptively positive during Screening, additional hair is extracted from the primary sample for the Extraction process. During this phase, drug substances are drawn from hair at significantly lower concentrations than methods like urine or saliva testing, making hair drug screening one of the most complex processes to conduct.
Positive screening results require validation through GC/MS, GC/MS/MS, or LC/MS/MS. Before proceeding to confirmation, presumptive positive samples are cleansed as appropriate. The full lab process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
