Hair examination is recognized as an effective means for identifying drug and alcohol consumption. Hair maintains a prolonged timeline of alcohol and drug usage by embedding biomarkers within the strands of hair as they grow. When collected near the scalp, hair can supply up to a three-month period of detection for alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and convenient to transport.
A hair sample measuring 1.5 inches and comprising around 200 strands (comparable to the width of a #2 pencil) near the scalp will produce 100mg, ideal for both screening and confirmation. For EtG, additional testing, and tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for weighing the sample is recommended. If scalp hair is unusable, a similar volume of body hair is acceptable. "Head hair" specifically denotes scalp hair. "Body hair" pertains to all other types, such as facial and axillary hair.
Process Overview
The processing stages in the lab for a drug test include Accessioning, Screening, Extraction, and Verification.
Accessioning involves introducing a specimen into the lab's system. Verification of proper sealing and shipping, allocation of a random LAN (Laboratory Accessioning Number), and handling of any pending data entry from the electronic chain of custody system are part of this step.
Screening performs an initial rapid analysis for substances of abuse. While cost-efficient to eliminate drug use in most specimens, a positive preliminary finding in Screening demands confirmation for legal acceptance. Presumptive positive screens necessitate further authentication.
In the event of a preliminary positive result during the Screening phase, additional hair is extracted from the main sample and processed for Extraction. This phase involves retrieving drugs from hair at concentrations much lower than other methods (e.g., urine or oral fluid), making hair drug screening a challenging process.
Confirmation for any positive result in Screening employs GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive hair samples are cleansed as necessary. The complete procedure from Accessioning to Confirmation undergoes both CAP (College of American Pathologists) Hair review and ISO/IEC 17025 accreditation.
