Accredited Drug Testing offers comprehensive hair follicle drug tests in Prestbury, Illinois. If a hair drug or alcohol test is required, we specialize in hair tests, available at our centers in all cities nationwide. Approximately 1.5 to 2 inches of hair from the head or body is typically needed. Hair testing can detect drugs, alcohol/ETG, or other specific substances.
Recently, hair follicle drug tests have become more common in drug testing practices. Employers, courts, and substance abuse professionals prefer hair tests over standard urine tests. These tests are ideal for zero-tolerance employers, courts, and probation cases. The main advantage includes a longer detection window up to 90 days, difficult to tamper with collection, although urine tests remain accurate for recent drug use within 5 days.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair analysis is perceived as an influential method for identifying drug and alcohol usage. Hair holds a prolonged record of alcohol and drug presence by embedding biomarkers in the strands’ fibers. If gathered near the scalp, it presents up to a 3-month detection period for alcohol and drugs. Hair collection is straightforward, reasonably hard to tamper with, and convenient to send.
A 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, the perfect sample for analysis and validation. For EtG, additional tests, or panels over 10, 150mg of hair is advisable. We suggest measuring the sample with a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be used. "Head hair" refers exclusively to scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The drug testing lab process includes these main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial integration of a sample into the laboratory system. This step involves confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from the electronic custody chain.
Screening performs a swift preliminary assessment for substance abuse. It provides a cost-efficient means to eliminate drug usage in most samples, but a positive screen requires confirmation for legal admissibility. Samples showing positivity in Screening mandate a secondary verification.
In cases of provisional positivity during the Screening phase, additional hair is extracted from the primary specimen for the Extraction phase. Here, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing technically challenging.
Verification of positive screening outcomes is executed by GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation if required. The entire lab operation, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being called "hair follicle tests," the analysis targets the hair strand itself, not the follicle below the scalp.
