Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair offers an extended history of substance use by encasing biomarkers within the growing hair's strands. When taken close to the scalp, hair can reveal up to a 3-month detection timeframe for alcohol and drugs. It's straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hairs (roughly the size of a #2 pencil) from near the scalp, will provide around 100mg, ideal for assessment and verification. For EtG, additional tests, and tests surpassing 10 panels, a 150mg specimen is advisable. We suggest using a jeweler's scale to weigh the specimen. Should scalp hair be lacking, a similar quantity of body hair can be used. When referencing head hair, we mean solely scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
Laboratory processing of drug test results involves four significant steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample within a lab's system. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry beyond what an electronic chain of custody system provides.
Screening consists of an initial rapid assessment for substances of misuse. While a cost-effective means to dismiss drug use in most samples, a positive screen must be validated for court admissibility. Samples that test presumptively positive require further confirmation.
For samples deemed presumptively positive during Screening, additional hair is taken from the initial sample for Extraction. In this step, drugs are extracted from hair at a far lower concentration than other methods (e.g., urine or oral fluid), hence hair drug screening being notably challenging to execute.
GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive screening results. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
