The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged timeline of alcohol and drug intake by embedding biomarkers within the strands as they grow. When hair is gathered close to the scalp, it can offer up to a three-month detection period for alcohol and drugs. Collecting hair is straightforward, difficult to tamper with, and easily transportable.
Obtaining a 1.5-inch segment comprising around 200 hair strands (roughly equivalent to a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, enhancements, and/or analyses exceeding 10 panels, a 150mg sample is advisable. For accurate measurement, we suggest using a jeweler's scale to weigh the specimen. In cases where scalp hair is inaccessible, the collection of a comparable amount of body hair is permissible. When we reference head hair, it exclusively implies scalp hair, whereas body hair denotes all other varieties (facial, armpit, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary procedure of incorporating a sample into a laboratory's framework. This step includes ensuring proper sealing and transportation of the sample, allocating a unique LAN (Laboratory Accessioning Number), and supplementing any ancillary data entry not supplied by an electronic chain of custody system.
Screening consists of an initial rapid assessment for drugs. Though Screening is a budget-friendly approach to exclude drug usage in the majority of samples, a positive result in screening necessitates confirmation for legal reliability. Presumptively positive samples from Screening must undergo further validation.
Should a sample yield a presumptive positive in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly minimized concentrations than in other methodologies (e.g., urine or oral fluids), rendering hair drug screening as one of the most intricate methodologies to execute.
Positive screening results undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive washing prior to confirmation if required. The entire laboratory process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
