Recently, there has been a rise in using the hair follicle drug test for substance screening. Employers, courts, and Substance Abuse professionals now often opt for hair drug testing over traditional urine tests. These tests are chosen by employers with zero-tolerance policies, courts, and for individuals on probation. Hair follicle tests offer the advantage of detecting drug use over a prolonged period, up to 90 days, with nearly impossible test tampering and observation during collection. However, urine tests remain most precise for detecting recent drug use within five days.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair strands offer a comprehensive timeline of substance use by encapsulating biomarkers within the growing fiber structure. When sampled close to the scalp, hair can reflect substance use within an approximate three-month window. The simplicity of collection, resistance to tampering, and convenience of shipping make hair samples advantageous.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp provides approximately 100mg of hair, which is optimal for both preliminary screening and confirmation. For EtG testing, additional panels beyond 10, or special add-ons, a sample of 150mg is preferred. Utilizing a jeweler’s scale is advised for weighing the sample. If scalp hair is not available, an equivalent volume of body hair is acceptable. Note that head hair refers solely to scalp hair, whereas body hair encompasses all other types such as facial and axillary hair.
Procedure Overview
The laboratory assessment of a drug test consists of four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates initial sample handling within laboratory systems, ensuring the sample's integrity in terms of proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and entering all requisite information not covered by automated custody systems.
Screening involves a preliminary evaluation for drug substances. Although cost-effective, Screening serves as a quick method to exclude drug use in most samples, a positive outcome necessitates subsequent verification to stand in legal settings. Samples indicating positive results in Screening must undergo further confirmation.
In cases where a sample shows presumptive positivity during Screening, additional hair is extracted from the initial sample for the Extraction phase. In this process, drug elements are isolated from hair, albeit at much lower concentrations compared to methods like urine or oral fluid testing, underscoring the complexity of hair drug testing procedures.
Validation of any positive screening outcomes occurs through GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples flagged as presumptive positives undergo washing before confirmation when needed. From Accessioning to Confirmation, every phase of laboratory processing is rigorously evaluated under the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
