Specializing in hair drug and alcohol tests, we have nationwide centers ready to perform these tests. Typically, 1.5 to 2 inches of head or body hair is required. Hair screenings can detect drugs, alcohol/ETG, or can be tailor-fitted to specific testing needs.
Hair follicle drug tests have gained popularity over the past few years as the preferred method for drug screening. Many organizations, including employers, courts, and substance abuse experts, now prefer hair tests over traditional urine tests. Hair tests are favored because of their ability to detect drug use over an extended period, up to 90 days, and they are difficult to tamper with. However, urine tests remain effective for spotting recent drug use within the past 5 days.

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. Hair offers a comprehensive timeline of drug and alcohol intake by encapsulating biomarkers within the fibers of the hair as it grows. When gathered close to the scalp, hair can present a detection period of up to around 3 months for both alcohol and drugs. Hair is straightforward to collect, less prone to tampering, and convenient to transport.
A 1.5-inch section of roughly 200 strands of hair (about the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is perfect for analysis and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. It is suggested to weigh the sample with a jeweler's scale. If scalp hair isn't accessible, a comparable quantity of body hair can be used. References to head hair specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, initial handling of a sample into a lab's system takes place. This process includes confirming the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing any remaining data entry not covered by an electronic chain of custody system.
Screening entails a preliminary quick analysis for substances of abuse. While Screening is an economical method to exclude drug use in most samples, a positive screen requires confirmation to be legal in court. Samples that test presumptively positive in Screening necessitate further confirmation.
Should a sample test presumptively positive during Screening, additional hair is taken from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging methodology to execute.
Confirmation of any positive screening results is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
