Hair analysis has emerged as an influential means for identifying drug and alcohol consumption. Hair retains a long-term record of substance use, capturing biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can offer a detection range for substances spanning up to about 3 months. Collecting hair is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the optimal sample size for testing and verification. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, the equivalent amount of body hair can be used. Scalp hair specifically denotes hair from the head, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into a laboratory’s system. This phase involves confirming the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and finalizing any necessary data entry not covered by an electronic chain of custody system.
Screening provides an initial rapid assessment for drug use. While Screening is an economical method to exclude drug use in most specimens, a positive result must be validated for admissibility in court. Samples that test presumptively positive during Screening need a subsequent confirmation.
If the Screening stage results in a presumptively positive finding, additional hair is extracted from the initial specimen for the Extraction process. This phase involves isolating drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a more complex procedure.
Verification of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed before validation as required. The entire lab workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
