Hair tests have gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of these substances by encasing biomarkers in the hair strand's fibers as it grows. If taken near the scalp, it provides nearly a 3-month period for detecting drugs and alcohol. The process of hair collection is straightforward, relatively tamper-proof, and easy to transport.
A hair sample of 1.5 inches, comprising around 200 strands (similar in size to a #2 pencil) nearest the scalp, yields 100mg, which is the optimal sample size for analysis and verification. For tests involving EtG, additional assays, or those exceeding 10 panels, a 150mg sample is advisable. We suggest measuring the hair sample using a jeweler’s scale. Should scalp hair be absent, a comparable quantity of body hair may be used. In reference to head hair, this implies only the hair on the scalp. Body hair includes all other hair forms (facial, axillary, etc.).
Process Overview
There are four key stages in processing a laboratory drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a laboratory’s framework. This incorporates confirming the sample's proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any further data input not furnished by an electronic chain of custody system.
Screening consists of an initial swift evaluation for drugs of abuse. Although Screening is a budget-friendly method to eliminate drug usage on most samples, a successful screen must be validated for court acceptance. Any samples indicating a preliminary positive in Screening necessitate a secondary validation.
If a sample is initially flagged as positive in Screening, additional hair is extracted from the original sample to set the stage for Extraction. During this phase, drugs are separated from hair at significantly reduced concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening a highly challenging methodology to execute.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing as required before confirmation. The entire laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and holds accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly known as "hair follicle tests", the test examines the hair strand and not the hair follicle beneath the scalp.
