Over time, hair testing has gained recognition as a potent method to detect alcohol and drug use. The hair captures a prolonged record of alcohol and drug consumption by embedding biomarkers within the fibers of the growing hair strands. When hair is cut close to the scalp, it can reveal a detection range reaching up to three months for substances like alcohol and other drugs. Collecting hair samples is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil's width), near the scalp provides about 100mg of hair, which is ideal for initial screening and further confirmation. For EtG or expanded tests beyond 10 panels, a specimen weighing 150mg is advisable. Using a jeweler’s scale, it's best to weigh the hair sample. If scalp hair cannot be obtained, an equivalent portion of body hair may be used. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses other hair forms (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result mainly comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the sample's preliminary processing into the laboratory's system, verifying proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any pending data entries absent from an electronic chain of custody.
Screening entails an initial rapid assessment for drug abuse. Despite being a cost-efficient approach to eliminate drug use for most samples, positive screenings must be verified for legal credibility. Samples that test as preliminarily positive during Screening necessitate a follow-up confirmation.
When a sample tests preliminarily positive in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. During Extraction, drugs are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging procedure.
Positive screening results are verified using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are thoroughly washed before confirmation if needed. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under the supervision of both the CAP (College of American Pathologists) Hair certification and accreditation to ISO / IEC 17025 standards.
