Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It offers a detailed timeline of alcohol and drug use by encasing biomarkers within the structure of the hair as it grows. When obtained near the scalp, hair can reveal substance use history for up to about three months. Collecting hair is straightforward, relatively tamper-resistant, and conveniently transportable.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil) close to the scalp provides 100mg of hair, which is the standard amount for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, a sample of 150mg is advised. Utilize a jeweler’s scale for precise specimen weighing. If scalp hair is absent, an equivalent volume of body hair can be used. References to head hair pertain specifically to scalp hair. Body hair includes all other hair classifications (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory's system. This step involves confirming proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data not captured by an electronic chain of custody system.
Screening entails an initial swift evaluation for drug abuse indicators. This cost-effective approach can exclude drug usage for most samples; however, a positive screen necessitates confirmation to be valid in court. Samples that are presumptively positive in Screening require a subsequent confirmation step.
Upon a presumptive positive finding in Screening, more hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at lower concentrations than other methods (such as urine or oral fluid), highlighting why hair drug testing represents a challenging methodology.
Confirmation of positive results from Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The complete laboratory procedure from Accessioning to Confirmation is reviewed with adherence to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
