Accredited Drug Testing provides thorough hair follicle drug testing services in Deer Park, Illinois. Specializing in both drug and alcohol hair testing, we have facilities across all cities nationwide ready to conduct these tests. Typically, to perform these tests, clients need 1.5 to 2 inches of hair from the head or body. Our hair analyses can detect drugs, alcohol/ETG, or be customized for different testing needs.
In the past few years, there's been an increase in using hair follicle tests for drug detection. Many employers, legal systems, and Substance Abuse professionals now prefer hair drug tests over conventional urine tests. Hair follicle drug testing is favored by employers with strict drug policies, legal systems, and probationary bodies due to its extended detection capability—up to 90 days—through direct observation, making it nearly foolproof against tampering. However, urine tests remain the most precise for recent drug use, within a 5-day window.

Utilizing hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair naturally archives a prolonged history of alcohol and drug involvement by entrapping biomarkers within the strands as they develop. When sourced close to the scalp, hair can offer roughly a 3-month detection timeframe for detecting alcohol and drug use. Hair sampling is straightforward, relatively tamper-resistant, and convenient for mailing.
A 1.5-inch collection of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for analysis and confirmation. For EtG, extra tests, or analyses exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample using a jeweler’s scale. If head hair isn't available, an equivalent volume of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The principal phases in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a lab’s system. This involves ensuring the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any missing data entry not provided by an electronic chain of custody system.
Screening entails an initial, rapid evaluation for illicit drug use. While Screening is an economical method for dismissing drug use in most samples, a positive result must be confirmed for judicial use. Samples suspected to be positive during Screening necessitate further confirmation.
When a sample shows a presumptive positive in the Screening phase, additional hair is obtained from the initial sample and prepared for Extraction. During Extraction, drugs are withdrawn from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.
Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation as required. The complete lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
