Hair analysis is recognized as an effective means for identifying substance use involving drugs and alcohol. Hair secures long-term drug and alcohol records by embedding biomarkers within the strands as they develop. When trimmed close to the scalp, hair offers an approximate 90-day window for alcohol and drug detection. Hair collection is straightforward, challenging to tamper with, and convenient for transport.
Collecting a 1.5-inch hair strip consisting of roughly 200 filaments (comparable to a #2 pencil's diameter) closely situated to the scalp yields 100mg of hair, forming the perfect sample for preliminary testing and verification. For EtG, supplementary tests, and/or testing beyond 10 panels, 150mg of hair is advisable. It's recommended to measure the sample weight with a jeweler's scale. In the absence of scalp hair, equivalent body hair can be gathered. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses every other hair kind (facial, axillary, etc.).
Process Overview
The key stages in laboratory evaluation of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the primary input of a sample into the lab's system. This step involves ensuring the sample's seal and shipment were conducted appropriately, generating a unique LAN (Laboratory Accessioning Number), and finalizing any remaining data input not addressed by an electronic chain of custody system.
Screening serves as a preliminary rapid evaluation for potential substance abuse. Although Screening serves as an economical approach to negate drug usage in the bulk of samples, a positive result in Screening must be confirmed for legal proceedings. Samples presumed positive through Screening necessitate a subsequent verification.
Should Screening imply a positive result, further hair from the original sample is utilized for the Extraction phase. During this phase, drugs are separated from hair in significantly lesser concentrations than other methods (e.g., urine or saliva), rendering hair drug analysis as the most challenging approach to execute.
Every positive outcome from Screening undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleaned prior to Confirmation, as necessary. The comprehensive lab workflow from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
