Accredited Drug Testing provides thorough hair follicle drug screening in Williamson, Illinois. If you require hair drug or alcohol testing, our expertise in hair testing is supported by numerous centers across the nation offering these tests. Typically, a length of 1.5 to 2 inches of hair from the crown or body is needed. Hair analysis can test for drugs, alcohol/ETG, and other customized options.
The trend in drug testing has increasingly turned toward hair follicle analysis. It's become a requirement by many employers, courts, and substance abuse experts as it provides a preferred alternative to urine tests. Those with zero-tolerance policies use hair tests for their extended detection period—up to 90 days—and reliable collection method, reducing the likelihood of tampering. However, urine tests remain most effective for drug use within the last 5 days.

Hair analysis has become widely recognized as a robust method for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strand, hair analysis can reveal long-term drug and alcohol use. If collected near the scalp, hair can indicate substance use over a period of up to 3 months. Hair is easy to gather, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches and consisting of around 200 hair strands, akin to the thickness of a #2 pencil, results in 100mg of hair, which is the optimal amount for both screening and confirmation. For tests such as EtG and those exceeding 10 panels, 150mg of hair is advised. It is suggested to use a jeweler’s scale for accuracy. In cases where scalp hair is inaccessible, an equivalent quantity of body hair can be utilized. When mentioning head hair, we specifically mean scalp hair, while body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The key stages in laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample entry into a lab's system. This step ensures the sample is correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data recording not provided by an electronic chain of custody.
During Screening, an initial rapid test is done for drugs of abuse. While Screening is cost-efficient for ruling out drug use in most samples, a positive result must be verified for legal proceedings. Any presumptive positives in Screening must undergo secondary confirmation.
If a sample tests presumptively positive in Screening, additional hair is prepared for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methods like urine or oral fluid, making hair drug screening one of the most challenging techniques to execute.
Confirmation of a positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation as required. The laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp.

The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
