Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair records a prolonged history of substance use by preserving biomarkers within the hair strands' fibers as they grow. When obtained near the scalp, hair samples can reveal up to roughly a 3-month period of drug and alcohol usage. The collection process for hair is straightforward, somewhat resistant to tampering, and easily transportable.
Gathering a 1.5-inch portion of roughly 200 hair strands from the scalp (comparable in size to a #2 pencil) yields 100mg of hair, which is the optimal sample for both screening and confirmation. When testing for EtG, additional substances, or more than 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair is not available, an equivalent volume of body hair can be substituted. It's important to note that 'head hair' specifically refers to scalp hair, whereas 'body hair' includes all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result primarily involves four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the initial introduction of a sample into a laboratory's database. This process includes ensuring the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing any additional data entry omitted by an electronic chain of custody system.
Screening performs an initial rapid assessment for drug use. While a cost-friendly approach to dismiss drug use in most cases, a positive Screening result requires validation for legal admissibility. Any presumptively positive samples found during Screening necessitate a follow-up confirmation.
Should a sample yield a presumptive positive in Screening, additional hair is retrieved from the original sample and readied for Extraction. At this juncture, drugs are isolated from hair at significantly lower concentrations than in other methods (such as urine or oral fluids), highlighting the complexity of hair drug screening.
Confirmation of any positive screening findings is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire laboratory processing from Accessioning to Confirmation is thoroughly reviewed under both the College of American Pathologists (CAP) Hair designation and the ISO / IEC 17025 accreditation standards.
