In Bristol, Vermont, Accredited Drug Testing offers thorough hair follicle drug screening. If a hair drug or alcohol analysis is required, our focus on hair testing stands out with centers across cities nationwide. Typically, 1.5 to 2 inches of hair from either the crown or body are needed. We can check for drugs, alcohol/ETG, and provide other custom testing solutions.
More recently, drug testing methods frequently incorporate hair follicle analysis. Many firms, courts, and substance abuse experts opt for hair tests over traditional urine analyses. Hair tests cater to employers with strict drug-free environments, judicial requirements, and probation needs. Their main advantage is the extended detection window, usually up to 90 days, coupled with a supervised process, making cheating nearly unfeasible. However, urine tests remain optimal for detecting recent drug use within 5 days.

Hair analysis has gained recognition as an effective means for detecting drug and alcohol consumption. The hair captures a long-term record of substance use by trapping markers in the strands as they grow. When collected near the scalp, it can reveal alcohol and drug use within a 90-day window. Hair collection is simple, tampering is challenging, and transportation is straightforward.
A sample measuring 1.5 inches and containing around 200 hair strands (approximating the thickness of a #2 pencil) near the scalp yields 100mg, which is the optimal quantity for analysis. For EtG, add-ons, or evaluations exceeding 10 panels, it's advisable to have 150mg of the hair. A jeweler's scale is recommended for weighing the sample. In the absence of scalp hair, a similar amount of body hair can be utilized. References to head hair specifically indicate scalp hair, whereas body hair encompasses alternative types (e.g., facial, axillary).
Process Overview
The drug test analysis in a laboratory involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory processing phase where a sample is logged into the lab's system. This step includes verifying the proper sealing and shipping of the sample, issuing a random Laboratory Accessioning Number (LAN), and inputting any additional data omitted from an electronic custody system.
Screening functions as an initial rapid assessment for substance abuse. Although cost-efficient for excluding drug use across multiple samples, a Screening result must undergo validation for court acceptance. Samples flagged as positive during Screening necessitate further confirmation.
In the event of a positive result at the Screening level, additional hair is extracted from the original specimen for Extraction. At this stage, substances are extracted at concentrations lower than those in alternative methods (e.g., urine or oral fluid), establishing hair testing as the most intricate method.
Verification of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as required before confirmation. The complete laboratory workflow from Accessioning to Confirmation is audited according to both the College of American Pathologists (CAP) Hair designation standards and ISO / IEC 17025 accreditation.
