Hair examinations have emerged as a potent means for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and other substances by enclosing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair offers up to roughly a three-month timeframe for detecting alcohol and other substances. Hair collection is straightforward, somewhat hard to tamper with, and easy to transport.
A hair sample measuring 1.5 inches, comprising about 200 hair strands (roughly equivalent to the diameter of a number 2 pencil) closest to the scalp, yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or assessments with more than 10 panels, it is advised to collect 150mg of the sample. We suggest using a jeweler’s scale for determining the specimen’s weight. If scalp hair cannot be obtained, an equivalent quantity of body hair is acceptable. References to head hair denote only scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The primary phases in the laboratory analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a specimen into a lab’s system. This step includes ensuring the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and filling in any additional information that was not part of the electronic chain of custody system.
Screening is an initial rapid assessment for abusive substances. Although Screening serves as a cost-efficient method to exclude substance usage in most cases, a positive screening outcome necessitates confirmation for it to be legally valid. Samples yielding presumptive positive results during Screening require a follow-up confirmation.
Should a sample turn up presumptive positive during the Screening stage, further hair is extracted from the original sample for the Extraction process. In this phase, drugs are isolated from hair at significantly lower concentrations than other approaches (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to execute.
The Confirmation of any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo cleansing prior to confirmation as appropriate. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 certification standards.
