In Plymouth, Wisconsin, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If a hair drug or alcohol test is needed, Accredited Drug Testing specializes in such tests, with facilities in every major city across the nation capable of performing this test. Typically, 1.5 to 2 inches of hair is required, taken from the crown or other body parts. Such tests can be conducted for drugs, alcohol/ETG, or other bespoke options.
Recently, hair follicle drug testing has become a more common method for drug detection. Employers, courts, and Substance Abuse professionals increasingly opt for hair drug testing over the standard urine test. Organizations with zero-tolerance policies, courts, and probationary programs utilize this method. A significant advantage is its extended detection period of up to 90 days, with supervised collection and minimal risk of tampering. However, urine tests remain the most precise for detecting very recent drug use within the past 5 days.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of substance use by embedding biomarkers within the fibers of advancing strands. When acquired near the scalp, hair offers nearly a 3-month period of detection for alcohol and other substances. Hair collection is straightforward, less prone to tampering, and convenient for transport.
A segment measuring 1.5 inches, comprising roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest the scalp yields 100mg, which is the optimal quantity for testing and verification. For tests like EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent volume of body hair can be gathered. "Head hair" strictly denotes scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary).
Process Overview
Four principal stages are pivotal in the lab processing of a drug test result, known as Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample’s initial entry into a lab's system. This phase ensures the sample's proper sealing and dispatch, assigns a random LAN (Laboratory Accessioning Number), and completes any further data input absent from an electronic chain of custody record.
Screening constitutes a preliminary assessment for drug abuse substances. Although Screening is a cost-efficient strategy for eliminating drug use suspicion in most samples, any positive indication necessitates validation to be legally admissible. Sample positives identified in Screening must undergo further confirmation.
Should a sample appear positive during Screening, additional hair is drawn from the primary sample and readied for Extraction. In this phase, drugs are isolated from hair at concentrations much lower than in alternative methods (such as urine or oral fluid), underscoring the complexity of hair drug screening in execution.
Verification of positive screens is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Limitations:
Note: Despite the common term "hair follicle tests", the analysis scrutinizes the hair strand rather than the follicle beneath the scalp.
