Typically, a length of 1.5 to 2 inches of hair from the head or body is necessary for the procedure. Hair analyses can screen for drugs, alcohol/ETG, or other tailored options.
Lately, hair follicle drug tests have become a more common approach in drug screening. Employers, courts, and Substance Abuse professionals favor them over typical urine tests. Hair follicle drug tests suit employers maintaining strict no-drug policies, courts, and probation individuals. A key advantage is the extended detection span, covering up to 90 days, collected under observation, making it nearly foolproof. However, for recent drug use within 5 days, urine tests retain the highest accuracy.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. The hair captures long-term evidence of such substances by embedding markers within its fibers as it grows. When collected near the scalp, hair can reveal a detection period of up to around three months for drugs and alcohol. The collection of hair is straightforward, moderately resistant to tampering, and simple to transport.
A 1.5-inch segment comprising approximately 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal sample size for both screening and confirmation. For performing EtG testing, additional tests, or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for accurate specimen measurement. If scalp hair is not accessible, a similar quantity of body hair can be utilized. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The lab processing for a drug test outcome comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a laboratory's system. It ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and finishes any additional entries not covered by an electronic chain of custody system.
Screening entails an initial rapid assessment for drug abuse. Although Screening is economical for excluding drug use in most cases, a positive outcome mandates confirmation for legal acceptability. All samples that test positive in Screening necessitate further confirmation.
When a sample tests positive during Screening, additional hair is drawn from the original specimen and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than in alternative methods (such as urine or oral fluid), underscoring the complexity of conducting hair drug screenings.
Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as required. The complete lab procedure, from Accessioning through to Confirmation, is thoroughly reviewed under the CAP (College of American Pathologists) Hair designation and accreditation compliant with ISO/IEC 17025 standards.
