Utilizing hair analysis is now regarded as an effective means for identifying substance use. Hair strands preserve a long-term record of substances by encapsulating biomarkers within the strands. When sampled near the scalp, hair offers a detection window of up to about 90 days for various substances. The collection process is straightforward, the risk of tampering is minimal, and it is convenient for shipping.
A sample measuring 1.5 inches, comprising approximately 200 strands (around the width of a #2 pencil), secured closest to the scalp, will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG and tests exceeding 10 panels, a 150mg sample is advised. We suggest weighing the hair on a jeweler’s scale. If head hair is not available, an equivalent amount of body hair can be used. Note that 'head hair' refers specifically to scalp hair, whereas 'body hair' encompasses all other types (such as facial or axillary).
Process Overview
There are four primary steps in the lab analysis of a drug screening: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the primary intake process into the lab system. This step ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input absent from an electronic chain of custody record.
Screening is a preliminary rapid test for potential substance misuse. Although Screening is a cost-efficient method to detect drug use in a majority of samples, a positive result requires confirmation for legal acceptability. Presumptive positives in Screening necessitate further confirmation.
Samples that test presumptively positive during Screening are subject to additional hair extraction from the original sample for the Extraction phase. Here, the drugs are isolated at much lower concentrations compared to other techniques (e.g., urine or oral fluids), making it the most complex method to conduct.
Confirmation for any positive results after screening is done using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo washing before confirmation if required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests," these actually analyze hair strands rather than the follicle beneath the scalp.
