Based in Olivette, Missouri, Accredited Drug Testing offers comprehensive hair follicle drug testing. For those requiring drug or alcohol hair testing, we specialize in these services and our centers are present in cities throughout the nation equipped to conduct hair tests. In most scenarios, 1.5 to 2 inches of hair from the head or body can be used. Various drugs, alcohol/ETG, or other tailored testing can be analyzed via hair samples.
The use of hair follicle drug tests has become increasingly prevalent in recent years for drug testing purposes. Employers, legal systems, and Substance Abuse specialists often now prefer this method over traditional urine tests. Those advocating zero-tolerance on drugs, courts, and probation clients favor hair testing because it covers a more extended detection timeframe, up to 90 days, is collected under supervision, and is notoriously difficult to deceive. However, urine tests remain unmatched in accuracy for drug use within the past five days.

The use of hair testing has gained recognition as an effective method for identifying alcohol and drug consumption. By capturing biomarkers within the strands of hair, it provides a lengthy history of alcohol and drug intake. Hair gathered near the scalp can offer a detection period of up to roughly three months for alcohol and drugs. This method of collection is straightforward, challenging to tamper with, and convenient to transport.
Collecting a 1.5-inch section containing around 200 hair strands (approximately the thickness of a #2 pencil), nearest to the scalp, results in a 100mg sample, which is ideal for screening and validation. For EtG, additional testing, and/or evaluations exceeding 10 panels, a specimen amount of 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Summary
The laboratory processing of a drug test result comprises four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab’s system. This step involves confirming the sample was sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry that isn't featured in an electronic chain of custody system.
The Screening step is a preliminary assessment for drugs of abuse. Although it is a cost-efficient technique for eliminating drug use in most samples, a positive screen must be confirmed for use in legal proceedings. Samples that test presumptively positive in Screening require further confirmation.
If a sample is positive in Screening, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are separated from the hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), explaining the complexity of hair drug screening.
Confirmation of any positive results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process prior to confirmation if necessary. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated per the CAP (College of American Pathologists) Hair program and ISO / IEC 17025 certification standards.
Benefits of hair drug testing:
Disadvantages:
Keep in mind, although often termed "hair follicle tests," the analysis is conducted on the hair strand and not the follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
