When seeking drug or alcohol testing using hair samples, our expertise ensures accurate results, with centers available nationwide to perform these tests. A required hair length of 1.5 to 2 inches is sufficient for analysis, whether from the head or body, to test for drugs, alcohol/ETG, or other tailored testing needs.
Hair follicle drug tests have become increasingly popular for drug testing in recent years. Many employers, judicial systems, and substance abuse experts prefer hair drug testing over urine samples. Employers with a strict anti-drug policy, courts, and individuals on probation rely on this test. The key advantage is its extended detection timeframe of up to 90 days, with an observed collection process, making it highly reliable. Despite this, urine tests remain accurate for detecting recent drug use within the last five days.

Hair testing has evolved into a robust method for identifying drug and alcohol consumption. Hair acts as a long-term record of alcohol and drug use by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair offers up to a roughly 3-month detection window for alcohol and drug analysis. Hair is straightforward to collect, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch segment comprising about 200 hair strands (approximately the width of a #2 pencil) near the scalp provides 100mg of hair, considered optimal for screening and confirmation tests. For EtG assessments, add-ons, and/or beyond 10-panel tests, a sample of 150mg is advisable. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be obtained. When referencing head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial intake of a sample into the lab’s system. This process ensures that the sample is properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry not provided by an electronic chain of custody system.
Screening provides an initial cursory check for drugs of abuse. Although Screening offers a cost-efficient way to rule out drug presence in most samples, any positive findings require confirmation for legal admissibility. Samples showing presumptive positives in Screening necessitate further confirmation.
Upon a presumptive positive result from the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In Extraction, drugs are drawn from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most complex technique to execute.
Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing as necessary before confirmation. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standard accreditation.
