Hair analysis is now recognized as a robust method for detecting substance and alcohol consumption. Hair strands offer a comprehensive timeline of substance exposure by embedding biomarkers within the hair fiber during growth. When sourced near the scalp, hair can reveal a detection span of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, somewhat hard to tamper with, and convenient for transport.
A hair segment of 1.5 inches consisting of about 200 hairs (comparable to the width of a #2 pencil) closest to the scalp yields approximately 100mg, providing the optimal sample for analysis. For EtG, additional tests, or panels exceeding 10, a weight of 150mg is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair isn't available, an equivalent quantity of body hair may be retrieved. Head hair specifically denotes scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The drug test result processing in the lab consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample to the lab's workflow. This step ensures the sample was correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data entry not automated by an electronic chain of custody system.
Screening is a preliminary assessment for substance trace. While it's a cost-effective approach to eliminating most samples’ drug presence, a positive screening outcome must be confirmed for legal acceptance. Presumptive positive samples at this stage need further verification.
Should a sample test presumptively positive during Screening, additional hair is extracted from the initial batch for the Extraction stage. This phase isolates drugs in hair at much lower levels compared to other techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive screenings is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples yielding a presumptive positive result undergo a washing process before confirmation if needed. The complete lab procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair standard and compliance with ISO / IEC 17025 accreditation.
