Hair testing has emerged as a robust method for detecting drug and alcohol usage. Hair strands capture a long-term record of alcohol and drug presence by locking biomarkers within their growing fibers. When gathered close to the scalp, hair offers a detection window of up to roughly 3 months for drugs and alcohol. This method is easy to collect, offers high resistance to tampering, and is straightforward to transport.
A 1.5-inch segment of about 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is the ideal amount for detailed screening and confirmation. For EtG, specified add-ons, and evaluations exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair isn’t available, an equivalent quantity of body hair is acceptable. The term "head hair" specifically denotes scalp hair. "Body hair" includes all other hair variations (facial, axillary, etc.).
Process Overview
The drug test result processing in a lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial incorporation of a sample into a lab’s system. It includes verifying proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid check for drugs of abuse. Although it is a cost-effective means of ruling out drug use in most samples, a positive result from Screening necessitates confirmation to be legally permissible. Samples that are presumptively positive in Screening require further confirmation.
For samples that test presumptively positive in Screening, additional hair is extracted from the original sample for Preparation for Extraction. During Extraction, drugs are isolated at lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology to execute.
Confirmation of any positive Screening outcome is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as needed. The complete process from Accessioning to Confirmation is evaluated under the guidance of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
