The use of hair testing has evolved into a robust means for detecting the consumption of drugs and alcohol. The hair captures biomarkers within the strands of growing hair, offering a prolonged history of substance use. When taken close to the scalp, it can reveal alcohol and drug usage over an approximately three-month period. Hair is easy to gather, challenging to tamper with, and straightforward to send.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar in size to a #2 pencil) from the area nearest to the scalp, yields 100mg, which is ideal for screening and confirmation tests. For EtG, additional requests, and/or tests exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is absent, an equivalent amount of body hair may be utilized. References to head hair specifically indicate scalp hair. Body hair encompasses all other hair types (such as facial and axillary).
Process Overview
Laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase where a sample is processed into a lab's system. This step involves verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not handled by an electronic chain of custody system.
Screening executes an initial rapid assessment for substances of abuse. Though Screening is an economical method for ruling out drug use in most samples, any positive result in this stage needs confirmation for legal admissibility. Presumptively positive Screening samples must undergo a secondary confirmation.
Upon a presumptive positive result during Screening, additional hair is extracted from the initial sample for the Extraction process. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening execution.
Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are presumptively positive are laundered as necessary before confirmation. The entire lab process, spanning from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
