Hair analysis is recognized as an effective method for identifying substance use, with hair fibers retaining biomarkers over time. When sampled near the scalp, hair can reveal drug and alcohol use within a roughly 3-month frame. Hair sampling is straightforward, challenging to tamper with, and convenient for transport.
Extracting a 1.5-inch piece consisting of around 200 strands (approximately the thickness of a #2 pencil) from the scalp yields 100mg, perfect for initial testing and verification. For EtG, additional panels, or tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing is suggested. When scalp hair isn't available, equivalent body hair can be used. Head hair refers solely to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the sample's introduction into the lab system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data not covered by electronic chain of custody systems.
Screening offers an initial, rapid drug presence check. Though Screening is an economical method for excluding drug use in most samples, a confirmed positive screen is essential for legal validity. Positive screenings necessitate secondary confirmation.
In cases of presumptive positivity during Screening, additional hair is extracted from the original specimen for further Extraction. This phase isolates drugs from the hair at concentrations lower than those in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmation of positive screens is through GC/MS, GC/MS/MS, or LC/MS/MS. Positive samples undergo appropriate washing before confirmation. The entire process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
