Specializing in hair assessments, we feature testing sites in every city across the nation ready to conduct these tests. Generally, we require 1.5 to 2 inches of hair on the crown or body. Hair evaluations can identify drugs, alcohol/ETG, or other personalized testing options.
Recently, the favored approach for drug assessments increasingly involves hair follicle examinations. Employers, judicial systems, and Substance Abuse specialists are now opting for hair screenings over traditional urine tests. They’re indispensable for zero-tolerance workplaces, courts, and probationary monitoring. The principal advantage is its extended detection span of up to 90 days, observed during collection, making it nearly tamper-proof. Yet, for detecting recent usage within five days, urine tests remain unmatched.

The application of hair testing has emerged as an effective means for detecting drug and alcohol consumption. The hair serves as a record keeper for alcohol and drug exposure by encapsulating biomarkers within the growing hair strand's fibers. Collecting hair near the scalp can reveal exposure to alcohol and other substances for an approximate timeline of three months. The collection of hair is straightforward, relatively resistant to tampering, and simple to transport.
A hair sample measuring 1.5 inches, roughly 200 strands or the size of a #2 pencil, taken from the area nearest to the scalp, typically supplies 100mg of hair, which is the preferred quantity for analysis and confirmation. In cases involving EtG, additional testing, or more than a 10-panel screen, a specimen weighing 150mg is advised. We suggest using a jeweler's scale to measure the specimen's weight. Should scalp hair not be viable, an equivalent amount of body hair is an acceptable substitute. References to head hair specifically denote scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The comprehensive laboratory method for processing a drug test comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning step initiates the process by integrating a sample into the laboratory's system, ensuring proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and finalizing supplementary data entry absent from an electronic chain of custody system.
The Screening phase performs a preliminary examination for drug presence. While Screening is an economical approach to exclude drug use in most samples, any positive indication requires confirmation to uphold in judicial proceedings. Samples that screen positively at this stage necessitate a follow-up confirmation.
When a sample tests positive in the Screening stage, additional hair is sourced from the original specimen for Extraction. During this stage, drugs are separated from hair at significantly lower concentrations than other testing methods (e.g., urine or oral fluid), highlighting why hair drug screening remains the most intricate methodology.
Confirmation of any positive screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washing before confirmation. The entire laboratory process encompassing Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
