Accredited Drug Testing offers comprehensive hair follicle drug testing in Butler, Wisconsin. Should you require a hair drug or alcohol test, Accredited Drug Testing is adept in hair testing, with centers nationwide equipped to conduct these tests. Ideally, 1.5 to 2 inches of hair on the scalp is required, though body hair might be used when necessary. Hair tests can detect drugs, alcohol/ETG, or tailored testing options.
Recently, the approach to drug testing has increasingly featured hair follicle tests. Numerous employers, courts, and Substance Abuse professionals now prefer hair drug tests over conventional urine tests. Hair follicle tests are employed by employers with strict drug policies, courts, and individuals on probation. They provide a longer window of detection for drug use, typically up to 90 days, are collected under observation, and are highly cheat-proof. However, if drug use within the past 5 days is in question, urine tests remain the most precise method.

Hair tests have gained recognition as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug use by embedding biomarkers within the strands of growing hair. When taken near the scalp, hair offers a detection window of up to roughly three months for alcohol and drugs. Hair collection is straightforward, moderately resistant to tampering, and easy to send.
A 1.5-inch sample comprising around 200 hair strands (roughly equivalent to the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, an equivalent amount of body hair may be used. “Head hair” specifically means scalp hair. “Body hair” encompasses all other hair types (facial, axillary, etc.).
Process Overview
The processing of a drug test result in the laboratory consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory step where a sample enters the laboratory system. This phase includes verifying that the sample was correctly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and doing any further data entry not covered by an electronic chain of custody system.
Screening involves an initial rapid test for drugs of abuse. While Screening is an economical way to exclude drug use in the majority of samples, a positive result from a screen needs confirmation to be legally valid. Any samples that screen presumptively positive require additional verification.
If a sample yields a presumptive positive result in Screening, additional hair is removed from the initial specimen and prepared for Extraction. In this stage, drugs are extracted from hair at a concentration significantly lower than in other testing modalities (e.g., urine or oral fluid), making hair drug tests the most complex to execute.
The Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.
