Hair assessments have increasingly been recognized as an effective means for identifying drug and alcohol intake. Hair can offer an extended historical record of substance use by embedding biomarkers within the strands as they grow. When taken near the scalp, hair samples can reveal substance use within roughly a three-month timeframe. Collecting hair is straightforward, not easy to tamper with, and convenient to transport.
For an optimal sample size, a 1.5-inch segment of about 200 hair strands (approximating the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For testing that incorporates EtG, additional parameters, and/or exceeds 10 panels, it is advised to collect 150mg. Utilizing a jeweler's scale to weigh the sample is advisable. If no scalp hair is available, an equivalent quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair (facial, axillary, etc.).
Process Overview
The drug testing procedure in the lab consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is first introduced into the laboratory system. It involves ensuring the sample is correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and adding any supplementary details not entered digitally via a chain of custody system.
Screening entails a preliminary, rapid assessment for substance misuse. Although cost-effective, a positive screening result must be validated to be legally defensible. Samples that yield a presumptive positive in Screening must undergo a secondary verification.
Should a sample appear presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are extracted from hair in much lower concentrations than other methods (like urine or oral fluid), which is why hair drug testing is the most challenging technique.
Confirmation of any screening positives is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if needed. The full lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair directive and the accreditation with ISO / IEC 17025 standards.
