Accredited Drug Testing offers comprehensive hair follicle drug testing services in Shorewood, Wisconsin. If you need a hair-based drug or alcohol test, our centers nationwide, including Shorewood, specialize in these tests. Generally, 1.5 to 2 inches of hair from the scalp or body can be used. Hair testing detects drugs, alcohol/ETG, or offers other customizable options.
Recently, hair follicle drug tests have become more prevalent in drug screening. More employers, courts, and substance abuse professionals now prefer hair tests over traditional urine tests. Employers with zero-tolerance drug policies, courts, and probation officers use hair tests because they provide a longer detection period—up to 90 days. While urine tests are still best for recent use, hair tests are nearly impossible to cheat due to observed collection.

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. The hair locks in biomarkers within its strands, offering a prolonged record of substance use. When collected from near the scalp, hair can reveal substance use over roughly a three-month span. Its ease of collection, difficulty to tamper with, and straightforward shipment add to its appeal.
A 1.5-inch section comprising around 200 hair strands (about the diameter of a #2 pencil) near the scalp yields 100mg, which is an optimal amount for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is suggested. A jeweler's scale is advisable for weighing the specimen. Should scalp hair be unavailable, the same quantity of body hair can be used. When discussing head hair, it refers solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test outcome include four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the procedure of incorporating a sample into the laboratory's system. This stage involves affirming that the sample’s seal and shipment were intact, assigning a LAN (Laboratory Accessioning Number) at random, and completing any remaining data entry absent from an electronic chain of custody system.
Screening provides an initial, expeditious assessment for substances of abuse. While Screening is a cost-efficient method to exclude drug use for most samples, a positive screen necessitates confirmation for legal admissibility. Positive samples in Screening require further confirmation.
Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. Drugs are isolated from the hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples get washed before confirmation as needed. From Accessioning through Confirmation, the entire laboratory process aligns with the standards set by the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
