Hair analysis is now recognized as a robust method for identifying drug and alcohol intake. Through its fibers, hair captures long-term drug and alcohol history by preserving biomarkers in the hair's structure. With samples taken near the scalp, hair can offer an estimated 3-month timeframe for detecting these substances. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
An ideal sample requires a 1.5-inch section of about 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp, delivering 100mg of hair for effective screening and validation. For tests involving EtG, additional factors, and/or panels over 10, a sample size of 150mg is advisable. We suggest using a jeweler's scale to weigh the sample. If scalp hair cannot be gathered, a matching quantity of body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other types like facial or axillary hair.
Process Overview
The drug test processing in the lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning focuses on the initial sample processing within the lab's system. This step ensures the sample was sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry absent from the electronic chain of custody system.
Screening entails a quick initial scan for substances of abuse. Screening is cost-effective for excluding drug use in many samples; however, any positive results require verification to be court-eligible. Samples that test positive preliminarily need secondary confirmation.
When a sample is initially positive in the Screening phase, additional hair is extracted from the specimen for the Extraction process. This involves obtaining drugs from hair at much lower concentrations compared to other methods (like urine or oral fluid), explaining the complexity of hair drug screening.
Positive screening confirmations are performed through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive samples undergo a wash prior to confirmation if required. The comprehensive procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair directive and validates ISO / IEC 17025 accreditation.
