Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-lasting record of drugs and alcohol by securing biomarkers within the strands of growing hair. Obtaining a sample from near the scalp can offer up to a 90-day detection timeframe for drugs and alcohol. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
Collecting a 1.5-inch section of around 200 strands of hair (roughly the width of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional components, or tests exceeding 10 panels, a sample of 150mg is advised. We suggest measuring the sample with a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair can be used. "Head hair" refers strictly to scalp hair. "Body hair" includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the first step of entering a sample into the laboratory system. This process includes validating that the sample is sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid check for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive screen requires confirmation to be court-admissible. Presumptively positive samples in Screening necessitate a secondary confirmation.
If Screening suggests positivity, additional hair is extracted from the initial sample and readied for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a complex methodology.
Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.
