Accredited Drug Testing offers full hair follicle drug testing in Red River, Wisconsin. If a hair or alcohol test is needed, our centers nationwide, including Red River, are equipped to conduct them. Typically, 1.5 to 2 inches of hair from the head or body is required. Our hair tests can detect drugs, alcohol/ETG, and offer personalized testing options.
The trend toward hair follicle drug tests has increased over the years. Employers, courts, and substance abuse experts often favor these tests over urine tests. They suit zero-tolerance policies held by employers and aid court and probation requirements. Their advantage lies in the longer detection window for substances, usually up to 90 days, and tests are nearly impossible to tamper with. For recent drug use (within 5 days), urine tests remain the gold standard.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It captures a prolonged history of substances by embedding biomarkers within the fibers of the hair as it grows. When hair is sampled close to the scalp, it offers a detection period of up to roughly three months for alcohol and other substances. The collection process is straightforward, with hair being relatively tamper-resistant and easy to transport.
Collecting a 1.5-inch segment of approximately 200 hair strands (equivalent in size to a #2 pencil) near the scalp provides about 100mg, an optimal quantity for both initial screening and verification. For tests involving EtG, additional panels, or tests surpassing 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to weigh the sample precisely. In the absence of scalp hair, an equivalent volume of body hair may be gathered. When discussing head hair, it specifically refers to scalp hair, while body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary stages in analyzing a drug test result at the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample entering the lab’s system. This process verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entries not captured by an electronic chain of custody system.
Screening includes an initial rapid assessment for abused substances. Although Screening is a cost-efficient method to rule out drug use in most samples, a positive screen must be confirmed for legal validity. Any sample flagged as presumptive positive during Screening mandates further confirmation.
When a sample is flagged as presumptively positive during Screening, additional hair from the original sample is utilized for Extraction. Here, drugs are isolated from the hair at significantly lower concentrations compared to other methods (such as urine or oral fluid). This makes hair drug screening one of the most complex methodologies to execute.
The Confirmation of any positive result from Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked as presumptive positive are cleaned before Confirmation as required. The entirety of the lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards accreditation.
