Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair can chronicle long-term substance use by embedding biomarkers within the strands as they grow. When the hair is clipped near the scalp, it allows for the detection of drugs and alcohol for up to three months. The collection process for hair is straightforward, challenging to tamper with, and easily transportable.
Collecting a 1.5-inch section of roughly 200 hair strands (about a pencil’s thickness) next to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For tests involving EtG, additional panels, or more than 10 panels, 150mg is the preferable specimen amount. It's advisable to use a jeweler's scale for precise measurement. If scalp hair can't be obtained, an equivalent amount of body hair may be used. "Head hair" specifies scalp hair exclusively, whereas "body hair" encompasses all other hair varieties (such as facial or axillary hair).
Process Overview
The primary steps in the laboratory analysis of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, where a sample is processed into a lab’s system. This involves confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening is a preliminary rapid assessment for drug abuse markers. Although it serves as a cost-effective method for omitting drug use from most samples, a positive result requires confirmation for legal admissibility. Any samples with a probable positive result in Screening need a follow-up confirmation.
In cases of presumptive positive results during Screening, additional hair is extracted from the initial sample for the Extraction phase. At this point, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or saliva), which accounts for hair drug screening being the most intricate procedure to execute.
Confirmation of any positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples undergo washing as necessary. The full laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
