Hair analysis has become recognized as an effective means for identifying the use of substances such as drugs and alcohol. Hair serves as a long-term record of substance use by capturing biomarkers in the hair's growing fibers. When obtained from near the scalp, hair can reveal usage of drugs and alcohol within roughly a 3-month timeframe. Its collection is straightforward, moderately resistant to tampering, and convenient for shipping.
A 1.5-inch segment of approximately 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG tests, additional panels, and tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing the sample. In cases where scalp hair is unavailable, a comparable amount of body hair can be gathered. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome encompasses four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample within a laboratory’s system. This process entails verifying the sample’s proper sealing and shipment, issuing a unique LAN (Laboratory Accessioning Number), and completing any related data entry not covered by an electronic chain of custody system.
Screening carries out an initial check for substances typically abused. Although Screening offers an economical method for ruling out drug usage across the majority of samples, a positive result necessitates confirmation for legal admissibility. Samples showing presumptive positivity in Screening require additional confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair in significantly lower concentrations compared to other methods (such as urine or oral fluid), marking hair drug screening as a relatively complex method.
Confirmation for any positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples presumed positive undergo necessary washing before confirmation. The complete laboratory continuum from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
