Hair testing is widely acknowledged as an effective method for identifying drug and alcohol use. Hair captures a long-term history of substances, retaining biomarkers within the strands as they grow. When taken near the scalp, hair offers up to a roughly 3-month detection period for alcohol and drugs. Obtaining hair is straightforward, difficult to tamper with, and simple to transport.
A hair sample of 1.5 inches, comprising about 200 strands (akin to the thickness of a #2 pencil) nearest the scalp, yields 100mg, the optimal quantity for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, it is advised to collect 150mg. Using a jeweler's scale for precise weighing is recommended. If scalp hair isn't available, an equal quantity of body hair is an alternative. Head hair specifically denotes scalp hair. Body hair includes all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of drug test outcomes encompasses four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the introduction of a sample into the lab's system. This encompasses ensuring that samples remain sealed and sent correctly, assigning a LAN (Laboratory Accessioning Number) randomly, and finalizing any extra data input absent from an electronic chain of custody system.
Screening conducts an initial rapid assessment of drug use. While Screening offers a cost-efficient means to rule out drug involvement for most samples, a positive screen necessitates confirmation to stand in legal proceedings. Presumptive positives require secondary verification.
When a sample is marked presumptively positive during Screening, additional hair is extracted from the initial sample for Preparation. In Extraction, drugs are isolated at much lower rates compared to methods like urine or oral fluid, thus making hair drug screening a challenging process.
Confirmation of positive screening results uses GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all presumptively positive samples are cleansed as necessary. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.
