Accredited Drug Testing provides comprehensive hair follicle testing for drugs in Winnetka, Illinois. If you're seeking a hair drug or alcohol test, Accredited Drug Testing is a specialist in hair analyses, with locations throughout the nation that can conduct a hair exam. Ideally, 1.5 to 2 inches of hair on the crown or body is required for most cases. Hair tests are analyzable for drugs, alcohol/ETG, or other specific testing needs.
Recently, hair follicle testing has become a more common approach in drug assessments. Many employers, judicial systems, and substance abuse experts mandate hair drug analysis instead of the typical urine exam. This method is preferred by employers enforcing zero-tolerance policies, courts, and probation officers. Its main advantage is an extensive drug detection window of approximately 90 days. The process is closely monitored and nearly unhackable. Nevertheless, urine tests still provide superior accuracy for detecting drugs within the previous 5 days.

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. It offers a prolonged record of substances by capturing biomarkers within the strands of hair as they grow. When collected near the scalp, hair can present around a three-month detection timeframe for alcohol and other substances. The collection process is straightforward, tampering is relatively challenging, and the samples are easily transportable.
Taking a 1.5-inch sample consisting of about 200 hair strands (approximately the width of a #2 pencil) from nearest the scalp provides 100mg, the optimum sample size for both screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for accurate measurement. In instances where scalp hair isn’t available, an equivalent amount of body hair can be obtained. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The four primary stages in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial intake of a sample into the laboratory system. This process includes checking that the sample has been sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any needed data entry not performed by an electronic chain of custody system.
In the Screening phase, an initial rapid assessment for drugs of abuse is conducted. Screening is a cost-efficient method to eliminate drug use across most samples. However, for court admissibility, a positive screen requires confirmation. Samples with a presumptive positive in Screening necessitate further confirmation.
For samples with a presumptive positive in the Screening phase, more hair is extracted from the initial sample 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 analysis one of the most challenging methodologies.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed prior to confirmation as necessary. The full process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.
