Hair testing is recognized as an effective means for identifying drug and alcohol consumption. The fibers within growing hair strands capture biomarkers, offering a historical record of substance use. When hair is sampled near the scalp, it can provide detection for alcohol and drugs over a period of roughly three months. Collecting hair is straightforward, and the sample is relatively resistant to tampering and easy to transport.
A 1.5-inch sample of around 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or for tests exceeding 10 panels, a sample of 150mg is advised. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair is unavailable, an equivalent amount of body hair can be used. By head hair, we mean only scalp hair; body hair refers to other types (facial, axillary, etc.).
Process Overview
The laboratory processing steps crucial to obtaining a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is processed into the laboratory's system. Tasks include verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entry not provided by an electronic chain of custody system.
Screening acts as a preliminary, cost-effective method to identify possible substance use across most samples; however, any positive result must undergo confirmation for legal acceptability. Samples yielding presumptive positives in Screening undergo secondary confirmation.
Upon obtaining a presumptive positive at the Screening stage, additional hair is retrieved from the initial sample for the Extraction process. Here, drugs are isolated from the hair at much lower concentrations compared to alternatives like urine or saliva, highlighting the complexity of hair drug screening.
Confirmation of any positive result during screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are washed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
