Hair testing is now considered a significant method for identifying the usage of drugs and alcohol. The hair captures long-term substance histories by enclosing markers within its growing strands. Collected near the scalp, hair can offer nearly a 3-month timeframe for detecting substances, including alcohol. Collecting hair is straightforward, with reduced chances of tampering, and is easily shipped.
A hair sample of 1.5 inches comprising roughly 200 strands (comparable to a #2 pencil) near the scalp yields 100mg, the optimal amount for initial and confirmatory tests. For EtG, additional tests, or more than 10-panel screenings, 150mg is advisable. Utilize a jeweler’s scale for weighing the specimen. If no scalp hair is available, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Meanwhile, body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary phases in a laboratory's analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sampling's initial submission into the laboratory's system, confirming the sample's correct sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and doing any additional required data entry when not furnished by an electronic chain of custody record.
Screening serves as a preliminary evaluation for substance misuse. While Screening is an economical means to eliminate drug usage in most samples, a positive screening must be validated for legal admissibility. Presumptive positive samples in Screening necessitate secondary confirmation.
When a sample tests presumptively positive in Screening, more hair is extracted from the primary sample for the Extraction phase. Here, drugs are pulled from hair at concentrations far lower than in other testing types (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.
The Confirmation of a positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All suspect positive samples undergo washing before confirmation if required. The laboratory process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.
