Accredited Drug Testing offers thorough hair follicle testing services in Dahlgren, Illinois. For those seeking hair drug or alcohol assessments, our expertise lies in hair evaluations, and we operate testing sites in every U.S. city, including options for hair analysis up to 2 inches from the head or body. These tests can screen for drugs, alcohol/ETG, or be tailored for other specific hair analyses.
In contemporary drug testing methods, hair follicle tests are becoming increasingly popular. Many firms, judicial systems, and addiction specialists prefer these over urine tests. Employers enforcing strict drug policies, judicial bodies, and probation personnel alike rely on these tests. The advantage of hair follicle examinations lies in their extensive drug detection timeline of up to 90 days, conducted under observation and exceedingly difficult to manipulate. However, detecting drug use within a recent 5-day window remains more precise with urine tests.

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair offers a prolonged timeline of substance use by capturing biomarkers within the growing hair strand. Collected near the scalp, hair samples can present up to a three-month detection range for substances. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp is ideal for a 100mg sample, suitable for screening and confirmation tests. For EtG, additional items, and/or tests exceeding 10 panels, a sample amounting to 150mg is advisable. A jeweler’s scale is suggested for weighing the sample. If scalp hair isn’t available, an equivalent quantity of body hair can be collected. References to head hair imply scalp hair exclusively, while body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result includes the four steps of Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the initial integration of a sample into the lab’s system occurs. This stage verifies the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry not covered by an electronic chain of custody system.
Screening provides a preliminary assessment for potential drug abuse. While this method is economical for excluding drug use in most samples, a positive result must undergo confirmation to be court-admissible. Presumptively positive Screening samples require secondary confirmation.
If a Screening stage sample tests presumptively positive, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are extracted at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is notably challenging.
Confirmation for positive screening results is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, any samples with presumptive positive results are washed as necessary. The laboratory process from Accessioning to Confirmation is reviewed both under the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.
