Hair testing has gained recognition as a robust method for detecting drug and alcohol consumption. The growth of hair fibers encapsulates biomarkers, thus providing a prolonged timeline of alcohol and drug presence. When sampled near the scalp, hair can reveal drug and alcohol use over a window of roughly three months. The collection process is straightforward, with minimal risk of tampering, and shipping is easy.
A 1.5-inch hair sample consisting of roughly 200 strands (about the circumference of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for thorough analysis. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. Utilizing a jeweler's scale for specimen weighing is recommended. In the absence of scalp hair, a comparable quantity of body hair may be used. The term "head hair" specifically refers to scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the sample into the laboratory’s workflow. This phase includes verifying the integrity and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data not entered electronically.
Screening conducts an initial rapid assessment for illicit substances. Although a cost-effective strategy to dismiss drug use in most cases, a positive screen requires confirmation to be legally valid. All presumptive positives in Screening necessitate a follow-up confirmation.
In instances of presumptive positivity during Screening, additional hair is extracted from the initial sample and subjected to Extraction. Here, drugs are isolated from hair at a significantly lower concentration compared to other techniques (such as urine or oral fluids), highlighting the complexity of hair drug testing.
Confirmation of any positive screen results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples flagged as presumptive positives undergo washing prior to confirmation as needed. The complete laboratory workflow, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair designation protocols and the ISO / IEC 17025 accreditation standards.
