Accredited Drug Testing provides comprehensive hair follicle drug testing services in St. David, Illinois. If a hair drug or alcohol test is what you require, Accredited Drug Testing is your specialist, with testing centers nationwide available for conducting hair tests. Typically, 1.5 to 2 inches of hair from the crown or body is needed. Hair tests can detect drugs, alcohol/ETG, and offer customized options.
In recent times, hair follicle drug testing has become more prevalent for drug testing. Employers, courts, and substance abuse professionals often prefer it over standard urine tests. Hair follicle drug tests serve employers enforcing zero-tolerance policies, the courts, and individuals on probation. The main advantage is a longer drug detection period of up to 90 days, using a supervised collection, which is hard to manipulate. However, urine tests remain most precise for recent 5-day drug use screening.

The use of hair testing has become recognized as a significant method in identifying drug and alcohol consumption. Hair captures a prolonged history of substances by holding biomarkers within the strands as they grow. When obtained near the scalp, hair offers nearly a 3-month detection time frame for alcohol and various drugs. It is easy to gather, somewhat challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is the perfect amount for testing and verification. For EtG, extra panels, or tests beyond 10 panels, 150mg of the hair sample is advisable. We suggest using a jeweler’s scale to measure the sample. If scalp hair is missing, an equivalent quantity of body hair could be used. When we mention head hair, we mean scalp hair only. Body hair refers to any other type (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a lab's system. This procedure confirms that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any further data processing not included in an electronic chain of custody system.
Screening is an initial rapid examination for drug presence. While Screening is economical for excluding drug use in most cases, a positive result needs further confirmation to be valid in legal proceedings. Samples showing a presumptive positive in Screening need a secondary confirmation.
Should a sample show a presumptive positive during Screening, additional hair is taken from the original sample and readied for Extraction. In Extraction, the hair releases drugs at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most complex technique to conduct.
Confirmation for any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are washed before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and in line with ISO / IEC 17025 standards.
