Accredited Drug Testing provides comprehensive hair follicle drug tests in Northfield, Minnesota. If you're in need of a test for drugs or alcohol, ATD excels in hair testing, with centers across the nation, including all cities. Typically, hair on your head of 1.5 to 2 inches is needed, or body hair can be used. Hair tests analyze for various substances including drugs, alcohol/ETG, or other personalized testing options.
Hair follicle drug tests have become a favored method in recent years. Employers, courts, and Substance Abuse experts often prefer it over regular urine tests. This testing method is a go-to for employers who enforce strict drug-free policies and for court-mandated and probationary needs. A main advantage is their extended detection period reaching up to 90 days, with tests conducted under observation, making them very challenging to compromise. However, for detecting substance use within the recent 5 days, urine tests remain the superior choice.

Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair samples offer a long-term overview of substance use by capturing biomarkers within the fibers of the developing hair strand. When obtained close to the scalp, hair allows for nearly a 3-month detection period for substances. Collecting hair is straightforward, challenging to alter, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hairs (comparable to a #2 pencil), closest to the scalp will yield 100mg of hair, which is the optimal quantity for testing and validation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advisable. It is advised to weigh the sample on a jeweler’s scale. If scalp hair is not available, a similar amount of body hair can be collected. When speaking of head hair, we refer exclusively to scalp hair. Body hair includes all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result encompasses four principal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of the sample into a lab's system. This step ensures that the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and concludes any supplementary data entry not covered by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient means to exclude drug use in most samples, a positive screening outcome requires confirmation for legal admissibility. Any samples deemed presumptive positive in Screening must undergo a secondary verification.
If a sample shows a presumptive positive outcome during Screening, additional hair is drawn from the initial specimen and readied for Extraction. In this phase, substances are removed from hair at concentrations much lower than in other techniques (e.g., urine or oral fluids), making hair drug testing one of the most challenging methods to execute.
Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as needed. The full lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
