Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair encapsulates a record of drugs and alcohol by capturing biomarkers within the strands as the hair grows. Collected near the scalp, hair can offer an approximate 3-month window for detecting drugs and alcohol. The collection process for hair is straightforward, challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to a #2 pencil), nearest the scalp, equates to 100mg, serving as the optimal amount for both screening and further analysis. For tests involving EtG, add-ons, or exceeding 10 panels, around 150mg of hair specimen is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair cannot be provided, a comparable quantity of body hair can be collected. "Head hair" specifically pertains to scalp hair. Conversely, "Body hair" encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
The four critical stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase, where a sample is processed into the laboratory’s system. This involves ensuring the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry not captured by an electronic chain of custody system.
Screening involves a preliminary assessment for the presence of drugs of abuse. Though Screening provides a budget-friendly means of negating drug use for the majority of samples, a positive screen must be validated to be considered legally admissible. Samples with presumptive positive results in Screening necessitate secondary verification.
In cases where Screening yields a presumptive positive, more hair is extracted from the primary specimen and prepared for the Extraction phase. Here, the drugs are removed from the hair at notably lesser concentrations than those in other methods (e.g., urine or oral fluid), contributing to the complexity of performing hair drug screening.
Verification of a positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positives undergo a washing step prior to confirmation if required. The entire lab procedure, from Accessioning through Confirmation, is scrutinized following the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.
