Recognized as an effective method, hair testing excels in detecting drugs and alcohol. By capturing biomarkers in the fibers, hair offers a prolonged history of alcohol and drug presence. Sourced near the scalp, it reveals substance use over an approximate three-month period. Collection is straightforward, challenging to tamper with, and hassle-free to transport.
Securing a 1.5-inch sample comprising roughly 200 hair strands (about the thickness of a #2 pencil) from the scalp yields 100mg of hair, the ideal quantity for screening and confirmation. For EtG, additional analyses, and/or extensive tests over 10 panels, a 150mg specimen is advisable. It is prudent to weigh the specimen using a jeweler’s scale. If scalp hair is inaccessible, a similar volume of body hair may be utilized. "Head hair" pertains strictly to scalp hair exclusively. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test result entails four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates a sample into a laboratory’s system. This entails confirming proper sealing and shipment of the sample, assigning a distinct LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening involves a preliminary prompt assessment for drugs of abuse. Although Screening is an economical approach for excluding drug use in most samples, a positive screening necessitates validation for legal admissibility. Any Screening samples that are presumptively positive require further confirmation.
In the event of a presumptive positive during Screening, additional hair is extracted and readied for Extraction. Here, drugs are drawn from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.
GC/MS, GC/MS/MS, or LC/MS/MS execute Confirmation of any positive screening outcome. All presumptive positive samples are cleansed before confirmation where applicable. The complete laboratory process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
