Hair tests are increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair captures long-term data of substance use by embedding biomarkers within its strands. When taken near the head, hair offers an approximate 3-month detection range for substances. Hair collection is straightforward, challenging to tamper with, and simple to mail.
A 1.5-inch segment comprising roughly 200 hair strands (about the width of a #2 pencil) closest to the scalp yields 100mg, which is the optimal sample for screening and validation. For EtG, additional tests, and tests exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weight accuracy. If scalp hair is unobtainable, a similar quantity of body hair is permissible. Head hair refers solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four principal phases in a lab's processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the lab’s database. This ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic chain of custody framework.
Screening entails a preliminary and rapid drug abuse check. While Screening is an economical procedure to establish drug non-usage on most samples, a positive result requires confirmation for court admissibility. Presumptive positive samples in Screening necessitate a follow-up confirmation.
Should a sample yield a presumptive positive in Screening, further hair is extracted from the original sample and readied for Extraction. This procedure extracts drugs from hair at lower concentrations than seen in other methods (e.g., urine or oral fluids), highlighting the complexity of conducting hair drug screening.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are rinsed before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
