Accredited Drug Testing provides comprehensive hair follicle drug evaluations in International Falls, Minnesota. Specializing in hair drug and alcohol testing, we operate testing centers across all U.S. cities capable of handling hair tests. Typically, 1.5 to 2 inches of hair from the scalp or body can be used. Hair tests can assess for drugs, alcohol/ETG, and other tailored testing solutions.
More recently, drug testing practices have increasingly adopted hair follicle tests. Employers, courts, and Substance Abuse professionals are opting for hair drug tests over traditional urine tests. Those enforcing zero-tolerance drug policies, as well as probationers, use hair tests. The key advantage is their extended detection range of up to 90 days, gathered through observed collections, making detection foolproof. However, urine tests remain the precise metric for recent drug use within five days.

Hair testing is now recognized as an effective method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and other substances by capturing biomarkers within the fibers of the continuously growing hair strand. When taken near the scalp, hair can reveal a detection period of up to approximately three months for alcohol and other substances. Hair is easy to gather, relatively hard to tamper with, and convenient to transport.
A 1.5-inch piece of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For EtG add-ons, and/or evaluations over 10 panels, a specimen of 150mg is advised. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be collected. In regard to head hair, we mean scalp hair specifically. Body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The four core stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into a lab’s system. This process includes checking the correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening offers an initial rapid assessment for the presence of drugs of abuse. While Screening is an economical approach to ruling out drug use in most samples, a positive screen necessitates verification to be valid in court. Any samples showing a presumptive positive in Screening need a subsequent confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is taken from the primary specimen for Extraction. In this stage, drugs are extracted from hair at a significantly lower concentration than in other methodologies (e.g., urine or oral fluid), which makes hair drug evaluation the most complex methodology to execute.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the test actually examines the hair strand and not the hair follicle beneath the scalp.
In International Falls, MN, opting for hair follicle testing over urine analysis offers significant advantages. Hair tests provide superior accuracy in detecting a wider range of substances over an extended timeframe, making the method reliable for verifying long-term drug use. Due to its comprehensive detection capacity, employers gain from a broader understanding of substance history in employees or applicants.
Unlike traditional urine tests, which have a limited detection window, hair follicle testing covers up to 90 days of use, allowing for a more thorough evaluation. This comprehensive insight is vital for organizations committed to maintaining strict drug-free environments.
