Accredited Drug Testing provides comprehensive hair follicle drug testing services in Green Valley, Illinois. Whether you're seeking a hair drug or alcohol test, our specialization in hair testing is well-suited to your needs, with testing centers available in cities nationwide. Generally, 1.5 to 2 inches of hair from your head, or body hair, is sufficient for testing. These tests can detect drugs, alcohol/ETG, or other specific substances.
Recently, the frequency of hair follicle drug testing has increased. This method is preferred by many employers, courts, and Substance Abuse professionals over standard urine tests. Zero-tolerance employers, courts, and probationary individuals find the longer detection window of hair follicle tests, one lasting up to 90 days, particularly beneficial. These tests are conducted in an observed setting, making it hard to tamper with. Still, urine tests remain the go-to option for detecting 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 has emerged as an effective method for identifying drug and alcohol consumption. Hair retains biomarkers in its growing fibers, offering a long-term record of alcohol and drug use. When sampled from near the scalp, hair can reveal alcohol and drug use for up to about three months. It's easy to gather, fairly resistant to tampering, and simple to transport.
A close-to-scalp 1.5-inch segment of roughly 200 hair strands (equivalent to a #2 pencil) yields 100mg, ideal for testing and confirmation. For EtG, supplemental tests, or tests exceeding 10 panels, a 150mg specimen is advised. Using a jeweler's scale for weighing the sample is suggested. If scalp hair is not available, an equivalent amount of body hair can be used. References to head hair pertain only to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of processing a sample into a lab’s system. This step ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening conducts a preliminary rapid assessment for drugs of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive screen mandates confirmation for court admissibility. Samples deemed presumptively positive during Screening require further confirmation.
If the Screening phase finds a sample presumptively positive, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are isolated from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug analysis the most challenging to perform.
Confirmation of any positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presupposed positive samples are adequately washed. Every step from Accessioning to Confirmation is reviewed following CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
