Hair examination is now acknowledged as an effective method for identifying the usage of drugs and alcohol. Hair retains a long-lasting record of drug and alcohol intake by embedding biomarkers within the fibers of the growing strand. When gathered close to the scalp, hair yields up to a three-month detection period for substances. Collecting hair is straightforward, relatively hard to alter, and simple to transport.
A 1.5-inch segment comprising roughly 200 hair strands (equivalent to the size of a #2 pencil) close to the scalp will equate to 100mg, the optimal amount for testing and validation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is suggested. We recommend using a jeweler’s scale to measure the specimen. If scalp hair cannot be obtained, a similar quantity of body hair might be taken. Referring to head hair specifically means scalp hair. Body hair includes all other types, such as facial and axillary hair.
Process Overview
The laboratory procedure for processing drug test results includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory process of entering a sample into a laboratory’s system. This step includes verifying proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input absent from an electronic custody chain system.
Screening performs an initial rapid scan for drugs. Although Screening is a cost-efficient approach to dismiss drug usage in most samples, a positive screen necessitates confirmation to be court-admissible. Any samples with presumed positive results during Screening must undergo a secondary confirmation.
If a sample tests presumptively positive in Screening, additional hair is extracted from the initial specimen and readied for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than from other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.
Confirmation of a positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are washed before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
