Hair testing is increasingly recognized as a valuable method for identifying drug and alcohol use. By embedding biomarkers within the strands, hair can capture a prolonged history of substance consumption. When obtained near the scalp, hair can exhibit a detection span of up to three months for both alcohol and drugs. The collection process is straightforward, tamper-resistant, and convenient for shipping.
A 1.5-inch hair portion, consisting of roughly 200 strands (similar to the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, which is the ideal quantity for both screening and confirmation tests. For EtG, additional analyses, or comprehensive tests beyond 10 panels, 150mg of the sample is advisable. It is beneficial to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent mass of body hair can be used. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types (like facial or axillary hair).
Process Overview
The laboratory procedure for processing a drug test result comprises four critical phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase, incorporating the sample into the laboratory framework. This step verifies the proper sealing and shipment of the sample, allocation of a random LAN (Laboratory Accessioning Number), and completion of any supplementary data entry absent in an electronic chain of custody setup.
Screening conducts an initial rapid evaluation for substances of abuse. Though Screening is an efficient method for dismissing drug use in most cases, a confirmed positive result is requisite for legal admissibility. Samples with presumptive positive results in Screening necessitate further confirmation.
Upon presumptive positivity in Screening, additional hair is utilized from the original sample for preparation in the Extraction phase. Here, drugs are extracted at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), underpinning the complexity of hair drug screening procedures.
GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to verify any positive screening outcomes. All presumptive positive samples undergo washing pre-confirmation as deemed necessary. The entire laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny influenced by CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests", the assessment evaluates the hair strand, not the follicle beneath the scalp.
